Quality sleep is a guarantee of health, vitality and ability to work, so you need to choose a bed carefully, carefully and responsibly. This is the piece of furniture that is not customary to change often, because a solid bed can last for decades.
How to choose a bed for a bedroom, choose a mattress, what design features you should pay attention to, will be discussed in this article.
Comfortable sleep directly depends on how the size of the bed corresponds to the anthropometric data of its owner. How to choose the right bed for the bedroom will be described below.
When choosing a bed, you should pay attention to the following:
- If the bed is chosen for a married couple, then its length should be oriented towards a higher family member. The optimal value would be the height of a person, plus 10-15 cm for a margin;
- To check whether the dimensions of the bed are suitable, it is necessary empirically - you need to lie on the bed with your arms thrown over your head and elbows straightened. It is necessary to do this with two people to make sure that there is enough space for both;
Advice. You can measure the required width at home, lying on the floor in the indicated position.
- The traditional shape of the bed is rectangular. This is the most optimal and convenient option in placement in space. If the area allows, then you can choose a bed of a non-standard shape. It can be a round, oval or arched bed;
Important! When choosing a bed of a non-standard shape, it must be taken into account that the bedspread on it will have to be made to order.
- It is recommended to pay attention to models with additional drawers - under the bed or at the head, which can be used to store bedding.
Main Models
Depending on the design features, beds are divided into the following types:
- With supporting backs, when there is a headboard and, sometimes, a footboard. These elements are interconnected with the help of side panels, which are called tsargs;
- In the form of a rectangle when 4 interconnected panels form a kind of podium;
- The structure with legs consists of 4 panels and hinged headboard and footboard;
- or other arbitrary form.
Price
Of course, the price of a bed will directly depend on its manufacturer:
- Foreign furniture will always be more expensive, material - furniture, which consists of solid or exotic natural wood species, is expensive. This also applies to design developments - custom-made furniture will also be an order of magnitude more expensive than standard furniture.
- If we talk about the manufacturer, then most people now purchase imported goods, hoping for better material from which furniture is made abroad. But, the problem is that the price of a really high-quality imported product is very high.
- The average price of a bed, which consists of such materials, is $ 1100 - $ 1700. Cheap bed imports mean savings on all materials and quality indicators. It makes sense to turn your attention to a not so expensive, but sometimes better category, these are domestic manufacturers, the price will be about $ 500 - $ 1000.
- Now, according to the materials, chipboard will be the most economical option here. The bed, which consists of chipboard, is quite similar in appearance to wood, but it will last much less. Wear is already visible after 3 - 4 years after purchase.
- Beds that are made of wrought iron or wood will last a very long time. Wooden ones can last for a long time, and these are decades, and metal ones - about a hundred years, only over time they will darken a little, but this will give them color.
Attention: there are quite expensive materials, for example, leather beds for the bedroom will be quite expensive. Therefore, before buying it is worth considering. How much material do you need.
How to choose a frame
The frame is not visible, but it plays a crucial role in the design of the bed. The service life of the product depends on its quality, and the comfort of its intended use.
The frame is the basis, which must be strong, durable and reliable.
There are several rules when choosing a bed frame:
- When choosing a frame, take into account the design of the product, the materials from which it is made and the dimensions relative to the size of the mattress;
- It is important that the maximum match between the dimensions of the frame and the mattress is achieved, so that the latter remains in a fixed position and does not move out, otherwise it will be uncomfortable to sleep on such a bed, and the frame will quickly become unusable;
- At the stage of purchasing a bed, it is necessary to verify the strength of the frame by evaluating the number of stiffening ribs in the form of jumpers and gratings, which should be optimal depending on the size of the structure. The number of fasteners directly depends on the size of the bed - the larger it is, the more stiffeners should be;
- It's not worth saving when buying a bed. The price of a reliable frame is higher, but such a bed will last longer;
- The most durable are frames made of ash, oak and beech;
- An important criterion for choosing a frame is its height. The traditional model is above the floor at a height of 50 cm.
Modern models with an oriental character are characterized by the location of the frame much lower.
The beds that can be found in modern interiors of American bedrooms, on the contrary, have a too high frame - up to 90 cm.
Such a model is not suitable for every person - except perhaps for those with growth above average.
Housing materials
Frames are considered the most durable and reliable, the material of which is solid wood or metal (see). One of the most reliable and aesthetically attractive is a wrought iron bed.
A bed made of natural wood is aesthetically attractive and environmentally friendly. Due to microcirculation in the pores of the wood, the material retains its natural qualities for a long time.
A wooden bed in the interior of the bedroom makes it warm and homely, and noble shades of wood create an atmosphere of sophistication and well-being.
A bed made of metal with elements of artistic forging, combines strength and external lightness of the structure. Openwork graceful laces allow the bed to look light and weightless.
For the manufacture of modern models of beds, veneered products from MDF and laminated chipboard are used. From these materials, you can create models with concise forms and fresh bright designs. Laminated chipboard can imitate the surface of many artificial and natural materials.
How to choose a bed base
The base rests on the frame, and serves as a plane on which the mattress is laid. In the people, this structural element of the bed is called a lattice or frame.
Three types of bases are common:
- The rack (wooden) base is a frame made of wood or metal, on which a certain number of bent or straight rails are fixed, located relative to each other with a small gap. For the manufacture of wooden poles, beech or birch is more often used.
The positive qualities of the slatted base include the presence of air circulation between the slats and the affordable cost of a bed with such a design.
Of the negative aspects of such a base, it is necessary to note the inevitable deformation of the mattress, which occurs over time, and a short service life due to the fact that the original shape and elasticity are lost.
- The metal base looks like a mesh, which is distinguished by a long service life (over 20 years), high orthopedic qualities and affordable cost. The disadvantage is the rigidity of the structure;
- The base made of plastic springs has sufficient strength, good orthopedic properties, long service life (over 15 years) and ease of use. The disadvantages include the high cost and little air circulation under the bed.
Important! If we compare the orthopedic properties of the bases, then the wooden bases are of the highest quality. It is also important that the base is well ventilated, so having drawers for linen should not be a priority when choosing a bed.
- The base with transformable orthopedic bars is the most perfect type of supports. They are equipped with a mechanism for individual adjustment of the head and foot of the bed by means of an electric drive and remote control. As additional options, it is possible to adjust the rigidity of the base and the function of vibration massage.
How to choose a mattress
Useful orthopedic qualities depend on the level of mattress rigidity, which should be at an average level. A mattress that is too hard does not contribute to the uniform maintenance of parts of the human body.
A mattress that is too soft deprives the human body of support, and leads to a curvature of the spine. The firmness of the mattress depends on its internal filler. There are spring and springless mattresses.
The quality of a spring mattress is determined by the level of spring fixation stiffness: the higher it is, the less comfortable the mattress is.
Springless mattresses are made on the basis of latex foam, which is a hypoallergenic, durable, environmentally friendly and well-ventilated material.
Important! To extend the life of the mattress, it must be turned over to the other side a week after purchase - and so on for 3 months. Then you can turn over once a year.
Choosing a double bed
For a long time, a bed can serve its owner not only as a place to relax, but also as an additional storage space. Do not waste meters of your free space under the mattress, it is better to find another use for that area.
Moreover, this will not affect the comfort of your stay. This is what lifts and drawers are designed for.
A drawer is a retractable device, which consists of wood, lies at the base of the bed and is pulled out with the help of slats. This is a very convenient way to store winter things, bedspreads and more, it is also a good option for small bedrooms, as it will not take up much space in the room.
Attention: But, nevertheless, for very small rooms it is better to pick up something without drawers, because you will have to leave space free for these drawers to leave.
So:
- The bed, which has a lifting mechanism, has special shock absorbers, with their use, the upper part of the bed is easily lifted and then fixed in a closed (upper or lower) position, which resembles the hood of a car. This is a fairly simple mechanism, even a child can do this work himself.
- Under the bed, along with a lifting mechanism, there is a place to store things. The look of this bed is suitable for small bedrooms, because you do not need to leave space for drawers and here you do not need free space on the sides.
Beds-transformers
Sometimes the area of the room does not allow you to put a full double bed due to the fact that the free space must be used during the daytime. It can be a small bedroom with several functional areas or a studio apartment. The requirements for a sleeping place in such conditions are maximum functionality and mobility.
A novelty is the wardrobe-bed, which, when assembled, stows away in a niche and looks like a wardrobe that occupies a minimum area in space. At night, the transformation mechanism turns it into a full-fledged sleeping place.
The sofa bed will be a good choice for a small apartment. It takes up little space and has built-in drawers for linen. During the day it can be used as a place to relax and decorate the room, and at night the sofa transforms into a spacious bed.
Ways to place a bed in a room
How to choose the right bed for the bedroom was described above - now you should decide on its placement in the room. The instruction is simple. Depending on the area and configuration of the room, there are several ways to position the bed in space.
There are also several rules for decorating a room with a bed:
- It is not recommended to install the foot of the bed to the doorway and the headboard to the window; it is also undesirable to place the bed along the line passing from the doorway to the window opening;
- For psychological comfort, massive structures in the form of beams and other elements should not be placed above the headboard;
- It will be uncomfortable if a mirror hangs opposite the bed;
- The location of the bed will be successful, in which the headboard will be located against a blank northern wall with a diagonal arrangement of the doorway;
- It is important to consider that there should be enough free space on both sides of the bed, so the wall-mounted location of the bed is only allowed for one sleeping person;
- The bed can be placed diagonally if the bedroom is narrow;
- Using dark furniture with light decoration of the walls of the bedroom, you can visually lower the height of the room;
- To make the room seem more spacious and lighter, you can choose the material of the bed to match the walls;
- To visually increase the height of the room, you can use a podium bed.
With the help of a competent selection of curtains, bedspreads, pillows and furniture upholstery, you can visually unify the interior and create a harmonious space. With plain walls of the bedroom, bright textiles and decorative elements are used to give it expressiveness.
Today we are talking about how to equip a dream bed: what sizes and mattresses to give preference to, how to choose with a lifting mechanism, what models are currently offered by manufacturers, we analyze the subtleties of materials, upholstery. We explain the features of the frame and many more parameters that are important to know in order to make a deliberate purchase.
Before you go to the store to inspect the assortment, take measurements of the room. This data will help with the choice - to cut off too small or large models. And also to understand exactly where to install a sleeping place.
1 What are the bed sizes?
The first item that is important to decide is the width, length and height. It should be comfortable for a person to sleep, lie in a free position during rest, or, for example, put a child next to him and at the same time feel comfortable -.
So, let's begin. Allocate standard dimensions for the width of the bed.
- One and a half - 140 cm.
- Double bed - 160 cm.
- Enlarged (known name - king size) - 180 cm.
- There are two-meter models, but less often.
It is worth noting that the parameters refer to a sleeping place - the frame can be as wide as you like. based on these indicators.
How to determine the width?
Lorries are suitable for children and teenagers - those who will sleep alone. For a married couple to sleep, double furniture of at least 160 cm is needed. If the family has a small child who often lies down with their parents, a width of more than 180 cm, and preferably 200 cm, is acceptable.
To choose the length, add 20 cm to the height of a person. If you sleep on a large pillow, then 30 cm. For people taller than 190 cm, individual measurements are needed - as a rule, the production of such costs 10% more. Do not neglect this point - after all, sleeping with legs hanging down is uncomfortable. It is better to overpay once, but then.
Height dimensions
There is more variety here, since depending on the style of the model there may be different heights. For example, high-tech beds have no legs at all, they stand on the floor.
The standard is 50 cm. It is believed that this is the most comfortable indicator for a person.
The choice is determined by the age, complexion and wishes of the future owner. So, for older people, low options are not suitable - it is more difficult to get up and lie down from them. If the height is sufficient, bed linen is made inside - retractable or ordinary.
And low ones are suitable only for certain interior styles.
2 About frame types
Before choosing, it is important to decide on the design. As a standard, it consists of three elements:, sidewalls and legs, which perform the function of a support. Since there are now a huge number of designs, the appearance of the frame varies, but the elements will be the same everywhere. Sometimes the legs are not visible, and the sidewalls play the role of supports.
To make a choice, consider the following rules.
- The legs make the overall structure visually lighter - it seems to “float” above the floor. It is recommended to choose for small rooms.
- Those models where there are no legs, but only "solid" walls - look more massive, besides, dirt is impossible under them. They are not advised to be placed in bedrooms for allergy sufferers or those who prefer a visually light interior.
How to choose frame material?
Wood
Natural breeds have always been used in production. The price depends on the type of wood - for example, teak or wenge will cost a lot to the future owner. But pine or birch are more budgetary. As a rule, they are ennobled: they are tinted under valuable breeds or veneered. Wooden frames are environmentally friendly, and even natural breeds age slowly. Even after serving for many years, wooden furniture will remain aesthetic, with all the cracks.
Metal
Premium options are found in copper and bronze, but are most commonly made from steel and aluminum. After that, the surface is coated with paint, nickel-plated and chrome-plated.
The steel structure is almost impossible to budge, it is heavy. The option is definitely not for single women or the elderly. Aluminum frames are lighter but more expensive.
Goods in the mass market are often made from rolled steel - this is the cheapest option.
Metal models are chosen by those for whom strength and durability are the main parameters. They are not afraid of mechanical shocks, scratches or other damage. This is a great option for families with. Durable material is the most practical choice in such cases.
wood boards
In the furniture industry, beds are often made from artificial fabrics such as MDF, chipboard and fiberboard. They are not environmentally friendly, but safe for health, as they are covered with large layers of varnish. Among these models there are "cellular" - when the structures inside are hollow. They are not only much cheaper, but also much lighter than standard options.
About foundation
It is bought separately from the frame. Previously, plywood or wood board was laid instead of the base - some unscrupulous manufacturers are doing this now.
A good base is rack. Reiki can be wooden or metal. If comfort is important or there are back problems, it is better to choose orthopedic bars. The more slats, the better - they bend more and allow the mattress to do the same - this has a positive effect on the condition of the back of the sleeper. By the way, the bending base lasts longer and is more practical than a wooden sheet.
3 How to choose the right bed : upholstery options
Premium class
Arpatek- one of the latest materials that feels like velvet skin to the touch. The composition of the fabric includes natural fibers. The upholstery is thin, but very durable and strong - the manufacturers promise that arpatek does not wear out over time, like leather. Today it is the most popular type of upholstery, but expensive.
Relax- very durable fabric, which is also easy to clean. She is recommended to choose or pet owners - in such families, furniture is "at risk".
Budget segment
Jacquard- a material with a pattern that is applied using thermal printing or weaving. This is a tough kind of fabric, but durable. Furniture upholstered in jacquard and aesthetically pleasing. There are different subspecies of the material, but we will not delve into their characteristics.
chenille- soft and pleasant to the touch upholstery, half synthetic. Very durable fabric that rarely wrinkles. Among the fabrics of the budget segment, they are the most popular. Their quality is lower compared to relax and arpatek, but the average user will not notice this if he does not expose the upholstery to some kind - specially dirty, set hot, and so on.
Flock- non-woven material. It is made from a sticky base and synthetic pile. Unpretentious, but not expensive.
Velours- fluffy fabric. It wears out quickly, and for a sleeping place it is not practical - especially, because there is constant contact with the head and back.
Tapestry- perhaps the most durable fabric from the entire list of budget options. It is difficult to cut it even with scissors - therefore, durability is ensured.
eco-leather- easy to clean. Such furniture is relevant for certain interior styles - for example, or industrial.
4 Additional features and storage systems
Before choosing the right bed for the bedroom, let's also decide on additional features. They can be a lifting mechanism and built-in storage.
For such structures, the base with the mattress rises - additional storage systems are often made under them. You can fold seasonal items or bedding sets. There are also designs with a lifting mechanism that help clean the bed, for example, in a closet.
There are three types.
Manual. The mechanism of work is as follows - a person makes an effort, the mattress with the base rises. Definitely not suitable for those who do not have stable physical strength: the elderly, teenagers. But such a modification is inexpensive, and besides, it certainly will not break.
Spring. The lift of such mechanisms is equipped with springs, they take on part of the load and facilitate the procedure. However, users of such structures note their fragility - the springs wear out over time, and they have to be changed.
with gas lift. The design works with the help of a shock absorber - a cylinder filled with nitrogen gas and a piston. The gas lift compresses under the pressure of the mattress with the base and takes on the entire load. You don’t have to make efforts to raise and lower such a structure - they are suitable for any person. Minus - the price. Much more expensive than manual modifications and spring ones.
5 Mattress
Hard or soft? Latex, polyurethane or mixed? Decide on your budget and requirements.
Universal - a mattress of average rigidity. A soft one is suitable for people with a healthy back, and it can be difficult to fall asleep on a hard one.
Natural filler materials are not the best option. And polyurethane or latex are suitable. They support a person of any weight well. More about mattresses in the video.
6 Style and design
Tips for choosing the appearance of furniture are always individual - it depends on the style of the room, decoration, wishes of the owners. But there are trends that we can observe in the design of bedrooms.
Professional designers often choose fabric upholstery for beds on projects. As a rule, this is a soft back with perforation - for example, a carriage tie or straight ties.

Currently, almost everyone has the opportunity to choose and buy a double bed that best fits into the existing interior, will be quite spacious and as comfortable as possible.
A double bed with a lifting mechanism and a box for the bed, allows you to abandon the furniture for storing bed linen.
If you are also going to buy new furniture, you first need to figure out how not to waste money.
Diagram of the overall dimensions of the base of the double bed.
Understanding how to choose a bed, you need to pay special attention to the frame.
This is the basis of the product, which is usually hidden from prying eyes, but the reliability and durability of the bed depends on it.
When choosing a bed in the bedroom, you need to pay attention to the following characteristics of the frame:
- compliance with the dimensions of the mattress;
- material of manufacture;
- external data.
The dimensions of the mattress and bed must exactly match each other.
When choosing a double bed, pay attention to how many lattices and lintels its frame has. The larger its dimensions, the more they should be.
You don't need to save too much. It is better to buy a high-quality and expensive double bed than a cheap one that will fail in 1-2 years.
Diagram of a longitudinal section of the bed.
The best quality frames are made of beech, ash and oak.
If you want to choose a bed with a frame made of natural wood, be careful. Some dubious manufacturing companies pass off various “wood-like” materials as a natural product.
This can be determined by the following factors:
- If the bed in the bedroom is painted, then the frame may not be made of natural wood. The color of the natural material is almost identical to the color of human skin.
- Run your fingernail along the frame with light pressure. If a small scratch or even a depression remains on the surface, then this is natural wood. However, this statement is true only for soft rocks.

Material selection
Scheme and instructions for assembling a double bed.
It is very important that the double bed is made of safe and high-quality material. Some companies use in the production of beds not only materials of inadequate quality, but also treat them with impregnations that can seriously harm health.
Frames are made from the following materials:
- natural wood;
- natural wood veneer;
- solid wood;
- various materials "under the tree".
It is best to buy a double bed, the frame of which is made of natural wood. This material will not poison you with harmful secretions. On the contrary, natural materials additionally purify the air.
If you're on a tight budget, look no further than wood-framed furniture. In most cases, this is a laminated chipboard (LDSP). This material is very easy to manufacture and is much cheaper than natural wood.
Metal can also be attributed to the number of environmentally friendly materials. For the manufacture of frames for double beds, as a rule, aluminum and titanium are used. Metal bed frames are inexpensive, look beautiful and last a long time. Discreet, but at the same time, attractive appearance allows you to fit such a bed into any interior.

Reliable design and ease of use
Example 1: double bed construction diagram.
Beech, various conifers, birch, oak are considered the most reliable and durable materials.
However, it must be remembered that beds made of these materials are quite expensive. There are reliable, safer and less expensive alternatives on the market today.
You can opt for a frame made of plywood or chipboard. However, in this case, you need to be very careful, because. there is a high probability of buying a product of inadequate quality.
To warn yourself against various surprises, carefully study the structure of the frame.
See if the veneer is crumbling, how tight the fasteners are, etc.
It is highly desirable that the material be impregnated with special antifungal agents.
Metal structures are superior in their characteristics to plywood, wood-like materials, and sometimes even natural wood.
Such frames will serve 20 years or more. The only drawback of this material is that it does not tolerate moisture well. However, today manufacturers use special paints and varnishes that provide reliable protection against corrosion.
Example 2: diagram of the design and individual components of a double bed.
It is important that the bed in the bedroom is not only reliable, but also easy to use. There is one important characteristic that many buyers do not even pay attention to.
It is very important that the height of the bed frame is comfortable for the person who will sleep on it. So, for example, a standard European-style bed frame has a height of about 50 cm, while an oriental-style bed will be located almost at floor level.
It must be remembered: the older the user of the bed, the more difficult it will be for him to get up from a low bed.
However, you don’t need to go to extremes either, as some people who buy beds with a frame about 1 m high do. Such a bed only looks beautiful, and sleeping on it is in most cases quite uncomfortable.

When choosing a mattress for a double bed, you first need to find the right base. It acts as a mattress support and is attached to the bed frame. Sometimes it is called a frame or a lattice. There are different types of bases. One of the most common options is a wooden base, also known as a slatted base.
The scheme of fastening the rollers to the base of the bed.
A rack frame is a base assembled from wood or metal. Straight or bent-glued slats are attached to it with a certain step. In most cases, such bases are made of birch and beech. The first option is considered more budgetary.
Among the main advantages of wooden bases are the following:
- relatively low cost;
- good ventilation properties.
The main disadvantages of rack frames:
- due to the fact that there is no support between the slats, after some time of use the mattress becomes wavy;
- relatively low service life - the mattress quickly loses its original elasticity and shape.
An equally popular material used to make mattress bases is plastic. Such frames are made using plastic spring elements.
Among their positive characteristics are:
- service life of more than 15 years;
- good orthopedic properties;
- ease of use;
- high strength.
The main disadvantages of plastic bases:
- the bottom of the mattress is not well ventilated;
- relatively high price.
One of the oldest and personally known to almost every person base options is a metal mesh. This basis has a number of advantages, namely:
- service life - over 25 years;
- excellent orthopedic performance;
- more affordable price compared to previously considered options.
But the network also has its drawbacks. Chief among them is that sometimes it can be extremely difficult to choose a good metal base bed, because. its assembly requires certain skills and knowledge, which are currently owned by very few specialists.
Many people believe that a mattress should be very firm. In reality, they are mistaken. A mattress that is too hard will not "adjust" to the user's body. However, it is also better to refuse a mattress that is too soft, because. it can cause curvature of the spine. The best option is an orthopedic mattress of medium hardness.
The firmness of a mattress is determined by its base. The mattress can be spring and springless. In most cases, orthopedic properties depend on how many springs are installed - the more there are, the higher the effect. However, it is important that the mounting of the springs is not too rigid. This is not only inconvenient, but also harmful.
Springless mattresses are based on latex foam. This material does not cause allergies, is characterized by a long service life, good ventilation and environmental friendliness.
Thus, when choosing a bed in the bedroom, it is necessary to take into account many important points. However, you can be sure that in this case you will definitely be satisfied with the purchase!
The seller is obliged to provide detailed information on the product: equipment, dimensions and what size mattress is required. Check that the price includes all the necessary items.
Comfortable size for two
The optimal width of the bed, when both spouses are comfortable, is 160 cm, this is the standard. There is enough space for everyone to sit comfortably and not interfere with the other. Slender and young spouses can be limited to one and a half (140 cm), and for full ones it is better to take a wider model (from 180 cm).
Foundation Reliability
It depends on how long the bed will last. Champion in strength and durability - orthopedic base. This is a metal frame with transverse slats, which are also called armor, lamellas or latoflexes. There is no risk of breakage of the frame itself, and failed lamellas are easily changed. The design maintains big loadings from 200 kg on a berth. An additional plus: the lattice provides the necessary ventilation of the mattress and increases its service life.
In the interior of any home, the bed plays an important role. According to statistics, a person spends almost a third of his life in a dream. Good sleep is the key to performance and well-being. And if you want to buy a new bed for your house, then you need to approach this issue more than seriously, because along with the bed you choose your future health. Qualified specialists say that almost all diseases that are associated with the back arise just because of poor-quality beds. Let's figure out how to choose the perfect bed for your bedroom.
frame
The main thing you should pay attention to is the frame of the sleeping bed itself, the duration of the service life depends on it. If the design is flimsy, then it is better not to buy such a bed, in a short time it can easily fail. The frame can rest on the backs or on the legs. It is believed that the bed is stronger if the support goes to the backs, but this also largely depends on the manufacturer. In principle, it does not matter which design you choose if it is expensive furniture. A bed is exactly that thing, the cost of which increases in proportion to the quality. A good bed cannot be cheap. Carved wooden beds, wrought iron beds are very popular not only because of their presentable appearance, but also because of their durability. But beds made of chipboard, chipboard, MDF are no longer so strong, although again it all depends on the design and manufacturer. In addition, it should be borne in mind that the mattress will be laid on the frame in the future, which means that its size must match the size of the mattress.
