Hello! Welcome to Furniture & Textiles. This article is about modern sofa fillers. Remember the fairy tale about the princess and the pea? Indeed, the young lady was a connoisseur of high-quality fillers for sofas. You, too, will not interfere with such skill. After all, sleeping or sitting on an uncomfortable couch is not a rewarding task. In order not to spend sleepless nights, like a princess from a fairy tale, let's figure out what affects the comfort of the sofa.

Types of sofa fillers

The smaller the diameter of the springs, and the greater their density per square meter, the better the orthopedic effect of the spring block. In such spring blocks, the springs can be covered with additional layers special materials: coconut coir, horse hair, polyurethane foam. The different density of each layer allows you to create more rigid or, conversely, softer seats and backs.

The spring block, reinforced with a steel frame-frame, keeps its shape better and longer.

It consists of barrel-shaped springs, each of which is packed in a fabric cover and act independently of each other. Such a block does not sag and does not create unnecessary vibrations when changing positions., it is also silent, because the springs do not touch each other. The springs have a diameter of 5-6 cm and a density of about 250 pieces per square meter, which allows them to compress-unclench under each part of the body separately and create a comfortable position for sleeping and sitting. This type of box spring is more commonly used in bed mattresses than in sofas.

Fillers without spring blocks

Fillers without springs can be divided into two groups. Hard fillers and soft fillers.

Fillers made of polyurethane foam (PPU)

There are two types of polyurethane foam.

Block PPU

Block PPU is sometimes called a "sandwich" because of the way it is produced. Represents thick sheets of polyurethane foam big size, different densities.

In production, sofa parts of the desired shape and thickness are cut from such sheets. The result is a sofa back or seat glued together from sheets of different densities (layers, like a sandwich) - from stiffer to softer.

Cast polyurethane foam

Initially has liquid state. It is poured into a mold, the future part of the sofa, and hardening occurs under the influence of pressure and temperature. The result is a block exactly the size and shape of a sofa cushion or seat.

The disadvantage of cast polyurethane foam is the "crust" formed on the surface of the foam, as a result of baking, such a crust does not pass air well and can create the greenhouse effect. The advantage is that cast products have smooth, comfortable shapes

PPU products are afraid of exposure to light. With constant exposure to light, they can crumble and collapse. Therefore, PPU parts are hidden in opaque fabric covers.

The quality of the finished product made of PUF is affected by the density of PUF, measured in kg / m?. Usually, polyurethane foam with a density of 30 to 40 kg / m? is used in furniture. The higher this value, the more durable the furniture will be. PPU with a density less than 25 kg/m? only suitable for decorative pillows. The density of polyurethane foam in a particular model of furniture is usually indicated in the model passport

Interesting! There are pillows that are filled with memory foam foam. They "remember" and keep the shape of the person sitting, adapt to the curves of the body. But as soon as you rise, the pillow takes its original state.

Polystyrene balls

An intermediate view between PPU and soft fillers. Reminds in appearance, balls of crumbled foam. They are usually used to make

bean bags. Furniture from such balls very comfortable and comfortable to sit on.

The disadvantage of this filler, is its rapid compaction. Because of what it is required to periodically top up the filler.

Soft fillers for sofas

First group soft fillers These are synthetic fillers..

Sintepon

Synthetic material produced in the form of a non-woven fabric. The material for its production is polyester fibers. The synthetic winterizer refers to heaters and fillers. In everyday life it is used to warm clothes and give it shape, it is applicable for filling soft toys, blankets and pillows.

In furniture, synthetic winterizer is used for filling sofa cushions, armchairs, chairs and sofa armrests. Often a synthetic winterizer is used as an additional layer in combination with another filler, usually it is the last one before the finishing upholstery.

Advantages of a synthetic winterizer low price,

disadvantages The synthetic winterizer does not hold its shape very well under significant loads, it can wrinkle. The production of synthetic winterizer has no common standard as a result, you can get to products with poor quality and with unhealthy additives that can result from the use of recycled raw materials in the production.

Sintepukh

Obtained by combing, winding polyester fibers. As a result of fleece, a material is formed that looks similar to natural down The combed fibers are treated with silicone and connected. The material has good volume and softness. Interestingly, synthetic down has more high performance in terms of heat saving and maintaining the shape of the product than its natural counterpart. For this, it is often used to make outer warm clothing.

In sofas, sintepuh is used to fill pillows and armrests.

To the virtues synthetic down can be attributed to the fact that it keeps its shape well and prevents the formation of fungi inside the sofa.

Comfortel

Synthetic small balls are made of polyester fibers. Used to fill sofa cushions, chairs, ottomans and bean bags.

Durafil

Synthetic material obtained by heat treatment and bonding the fibers to the base. At the same time, the fibers "grow" from the base like grass vertically. Due to this, the material has good performance elasticity and shape retention.

Advantages does not absorb moisture good stability flammable, has antibacterial properties

It is a canvas with a large volume. It can be made both from natural fibers - cotton or wool, and from synthetic polyester.

Visually, the material resembles a lush blanket. The material can have a different density, due to which sofas with periotec can have different stiffness

Development of Russian scientists. Appeared in 2004. Hollofiber is registered as trademark. Thanks to their unique properties and at an affordable price, holofiber is gradually replacing other synthetic fillers from the market.

The material is obtained by twisting and "splicing" synthetic fibers. As a result, a spiral filler is formed which has many internal air pores. At the same time, the material has a homogeneous structure, due to which it keeps its shape well and retains heat.

In the furniture industry, it is used to fill sofa cushions. and sofa seats.

Advantages:Does not absorb moisture, Does not break down in the sun Does not absorb odors. Prevents fungus from spreading. Environmentally friendly Has properties of self-healing - takes the primary form after removal of the load.

Struttofiber

Struttofiber is a relatively young product. It was born in 2012 thanks to the invention of the engineers of the Podolsk factory of nonwoven materials. The birth of this filler was facilitated by the desire to replace obsolete foam rubber. Struttofiber entered the market as an inexpensive alternative and substitute for foam rubber.

The name of the filler is compound and comes from the words Strutto (Italian) - vertically located and Fiber (English) fiber. The name speaks for itself. The material consists of vertical fibers. Due to this arrangement, it has good elasticity and density.

Polyester is used in the production of fibers, which makes the material inexpensive. Strutofiber is used both in mattresses and for filling upholstered furniture.

Advantages:

• long term services
• moisture resistant
• not combustible
• does not allow microorganisms and mites to multiply in their environment
• elastic and comfortable when sitting and lying

Disadvantages::

despite the long service life, the material still shrinks and, with prolonged load in one place, deflections may form over time.

Foam fillers

Foam rubber is one of the old and budget types of fillers. Foam rubber can be used in the form of small pieces that fill the frame of the sofa or in the form of sheets when the foam sheet is equal to the size of the sofa element.

Filling with pieces quickly rolls down and begins to sag. Therefore, it is better to take a sofa with sheet foam rubber.

Foam rubber is more often used as an additional layer in the construction of sofas.

General lack of foam rubber short service life, during operation, the foam rubber loses its shape, sags.

To dignity can be attributed low price.

Let me summarize the synthetic soft fillers. The materials are worthy of choice. They have good strength and performance characteristics and relatively low price. When choosing this group, you should pay attention to the density and thickness.

The second group of soft fillers are fillers made of synthetic materials..

natural latex

Latex is obtained from the sap of the rubber tree. During vulcanization, latex forms a cellular structure with millions of cells, which are responsible for hygroscopicity and air exchange.

Latex is very durable and durable material does not cause allergies.

The main disadvantage is the high price. Therefore, latex is usually used in the production of expensive furniture.

Felt

Felt is both natural and artificial origin. Natural felt is produced from wool through the process of influence. Felt is used in sofa fillers as an additional layer. As a rule, felt is placed directly under the upholstery of the sofa. Due to its low thermal conductivity, felt creates a cozy and warm sofa seat. The thickness of sofa felt is from 0.5 to 2 cm.

Dignity felt naturalness and excellent heat-insulating characteristics

Coir filler

Fiber filler coconut trees Also called coconut tow. The raw materials for the production of this filler are the fibers of the trunks and fruits of coconut palms. The fibers are like dense threads. Coconut fibers are compacted by pressing. The result is a dense air-penetrating structure. In sofas, coconut tow is rarely used. It is mainly used in children's mattresses. The material breathes well and passes water well and does not retain water. So, even if the baby had an embarrassment, he will not have to sleep on the wet ..

Advantages good water and air permeability, low price, good rigidity and durability

seaweed filler

Algae filler is used in sofas as additional material. Seagrass is mainly used for stuffing pillows and blankets. It can also be used to fill sofa cushions. The material is very comfortable to sit on.

disadvantage is a low density and because of this, the pillows can fall off.

Advantages comfort, natural material, in contact with the heat of the human body, algae are able to emit the smell of the sea - in fact, the smell of iodine.

horsehair filler

Horsehair is almost never used as a filler for sofas. Unless in exclusive models. Manufacturing process very laborious and therefore filler from horse hair has a very high price. But in the end it turns out very durable and comfortable material. The hair is breathable and does not absorb moisture.

Advantages durability, comfort, naturalness

Flaw high price

What filler for upholstered furniture is better?

You can answer this question by comparing fillers according to certain criteria. And already within each of the selected criteria to find a leader.

The best filler in terms of service life

If in the production of the filler were used quality materials, then there is no clear leader. Spring blocks and PPU will also serve well. Foam rubber noticeably lags behind

Usually service life

• Spring blocks 7-10 years.
• PPU 5-8 years.
• Hollofiber 5-10 years
• Foam rubber 3-5 years

When buying a sofa, always find out the density of the filler. The higher the density, the better. The durability of the sofa depends on the density.

The best fillers depending on the purpose of the sofa

The choice of filler depends on the main purpose of the sofa.

• If the sofa is going to be used for sleeping, it is better to choose models filled with independent spring blocks. It will be good to sleep on latex.
• Sofas for heavy seating- the filler is suitable both from spring blocks and from polyurethane foam and holofiber
• Sofas with light load and occasional use. all the described fillers will cope with this task. Therefore, you can save.

Now, you are ready to choose the filler of the sofa and I think that you can even teach the sellers in furniture stores)))

Buyers are looking for furniture "by clothes". Whereas internal organization(filler for furniture) has where greater value. After all, it is the filler that sets the rigidity and softness of the seat; the life of the sofa largely depends on it. Approach the choice of "stuffing" wisely. Otherwise, after a couple of years, you run the risk of getting a seated chair in beautiful upholstery.

So that characteristic dents "from the fifth point" do not remain on the armchair and sofa, it is important to choose a model with the right filler.

Furniture filler: classification

Two designs of upholstered furniture seat filler are common: with a spring block and without springs. In the first case, continuous weaving springs are “wrapped” with several layers of covering materials: coconut coir, horsehair, polyurethane foam (PUF), etc. The different density of each layer allows you to create more rigid or, conversely, softer seat and back cushions. In the case of springless fillers, a block of cast polyurethane foam acts as the "core".

Where is your cover? Pay attention to the presence or absence of a technical cover under the upholstery, especially if the latter can be removed. The fact is that under the influence of light, PPU is destroyed, begins to turn yellow and crumble. If the pillows are “in the air” even for a short time while the cover is being washed, upholstered furniture will not last even a couple of years. A priori, a technical cover is available in all “multilayer” pillows made of block PU foam. They also make it in seats with molded polyurethane foam, which is complemented by a layer of comfort.

The second type is cast PPU. It is made directly to furniture factory: with a composition resembling sour cream in consistency, fill the workpiece. Begins chemical reaction, and PPU hardens under pressure. And at the output we have a block exactly the size and shape of a sofa cushion: no scraps and waste! But cast PPU also has a drawback: a characteristic “crust” is formed on the surface of the block, which breathes poorly.

Cast polyurethane foam is cast strictly according to the shape of the product or its individual parts - for each new chair or pillow they make their own blank (in which a chemical reaction takes place). Products of a bizarre shape otherwise simply cannot be made. This significantly increases the cost of a sofa or chair.

An example of a cast foam: the blank completely repeats the contour of the future chair.

PPU density. The density of polyurethane foam is decisive. The average range is from 30 to 40 kg / m³: the higher this figure, the harder and, therefore, more durable upholstered furniture will be. The most delicate polyurethane foam for furniture (less than 25 kg / m³) is only suitable for decorative pillows. The "contents" of the seat of an armchair or sofa can be specified by the model passport. Many manufacturers offer several options to choose from or allow you to replace the basic hard components with softer ones. Filling from layers of block polyurethane foam for furniture is cheaper than cast.

Trademarks of polyurethane

The composition of PPU is not the same. The Russian generalized name "polyurethane foam" corresponds to many foreign analogues: lokfoam, vibrofoam, baltex, technolat, foamex (USA), moltopren (Germany), allofoam (Canada). Some pillows are filled with memory foam. They know how to keep their shape and literally envelop the person sitting, adjusting to the curves of the body. But as soon as you rise, the filling quickly “straightens”, taking its original position.

An alternative to furniture foam

There are two alternatives polyurethane foam filler. Firstly, these are polystyrene balls (reminiscent of crushed polystyrene in appearance). On their basis, most bean bags are made. The balls sit out quite quickly, periodically they have to be filled up to the desired volume: get ready for regular additional expenses.

Loose filler literally envelops the body. Sitting in this chair is incredibly comfortable.

Secondly, it is natural latex - it is used in expensive upholstered furniture. When a discerning client fundamentally does not want to deal with synthetic materials. Latex is obtained from the sap of the rubber tree, or hevea. When foaming, millions of cells are formed in its structure, which are responsible for hygroscopicity and air exchange. One of the advantages of the material is its durability: the service life of latex is over 10 years, while the traditional PPU block is designed for only five years (a maximum of eight in expensive furniture). Another important quality of latex is hypoallergenicity. However, the cost of a product based on latex is quite high.

Latex is considered to be the best filler for upholstered furniture. The only drawback is the high price of the finished product.

You can answer this question by comparing fillers according to certain criteria. And already within each of the selected criteria to find a leader.

"Snake" (zigzag springs) is a type of springs used in furniture production. Zigzag springs, work in tension, they are usually used in bases soft elements, as a rule, these are soft elements of furniture - seats.

The springs are attached to the frame of the sofa in the transverse direction. The number of springs in the seats of upholstered furniture depends on the size and purpose of the product. Zigzag springs are used in mattresses, beds, couches and sofa beds. Also, "snake" springs are also installed in the backs of soft furniture elements in the form of ready-made spring structures.

Exist various ways fastening springs "snake" to wooden and metal frames. The simplest kind fastenings - steel brackets made of sheet steel or wire.
The frame of the product with a base of "snake" springs is stable and does not wobble. Springs of this type provide a weak orthopedic effect. The main advantage of using "Snake" springs is the evenness of the base of the sofa and its noiselessness during operation.

Spring block "Bonnel".

Spring blocks consist of Bonnell type springs fastened together with a spiral of high-carbon steel spring wire.

The spiral is fixed with "locks" on the first and last turn, which eliminates spontaneous twisting.

An important difference between Bonnel spring blocks and a block of independent springs is as follows:

The Bonnell spring block is without a doubt the most popular and recognizable type of spring block in the world. High reliability, simplicity and affordable price products are the main reasons for its mass and widespread use.

Advantages of Bonnel spring blocks.

• Spring block Bonnel (Bonnel) withstands heavy loads. People with a lot of weight - more than 110 kg are recommended to use springs of this particular series.
• Long service life (durability) - spring block Bonnel retains its elastic properties for a long time.
• Since the double-conical Bonnel spring block creates a large volume of air in the mattress, such a mattress has a good moisture exchange.
• Low price - its production is relatively inexpensive.

Disadvantages of Bonnel spring blocks.

• Due to the connections of individual springs with each other, surface elasticity is obtained (you press one spring, the neighboring ones also work). Therefore, the ability to take the form of a human body in such springs is not optimal.
• Currently, the use of Bonnel spring blocks is declining. However, among great variety are produced and sufficient good mattresses and furniture with reinforced springs - such products are quite high quality.

Block of independent springs

Block of independent springs- this is a block in which each spring is enclosed in a separate case made of spunbond or fibertex non-woven material. The springs are not bonded to each other, each spring is compressed separately as much as the pressure is applied to it, regardless of the load on adjacent springs.

Independent springs are sewn into separate textile covers (pockets). B The block of independent springs is glued with spunbond at the top and bottom, which makes it possible to accurately maintain the geometric dimensions of the block.

Cases with independent springs are interconnected. These connections must be fundamentally concentric so that each spring can show its elastic properties (point elasticity), i.e., without involving neighboring springs, distribute the load pointwise. This allows you to achieve an anatomical effect: the mattress follows the contours of the person lying on it, the spine remains straight, the back muscles are relaxed, which reduces the risk of back pain and diseases of the musculoskeletal system.

Advantages of the block of independent springs

How often do you choose upholstered furniture in appearance without thinking about what is inside it? But internal filling is of no less importance. The reliability and durability of the seat, back and armrests, as well as the comfort and convenience of landing, directly depend on the filler for sofas. Therefore, it is necessary to approach his choice no less carefully than to choose the color of the upholstery or the shape of the sofa.

Which is better - springs or highly elastic polyurethane foam (PPU)? We talk about the most popular materials and help you decide which sofa filler is better to choose in order to get a comfortable and durable place to relax for many years.

What is hidden inside: a general classification of fillers

There are two large groups of upholstered furniture fillers: with springs and without springs.

In the first case, on the springs cylindrical shape or the base of the spring "snake" several layers of natural or artificial cover material are laid - coconut coir, latex, foam rubber, felt, etc. Different density of this or that coating and many options for springs allow you to create fillings different degrees rigidity.

Springless fillers are based on highly elastic polyurethane foam (PPU, furniture foam rubber) - an inexpensive, but durable and resilient artificial material.

If you look at the sectional image of the sofa, you will see that all its internal content is stacked on top of each other in layers. This method of laying is commonly called a “layer cake”: alternating different materialsallows sofas and armchairs to be hard or soft, gives the surface elastic resilience, airiness and relief, which contributes to comfortable rest and relieves stress on the spine.

Springs

The spring block is of two types: with dependent (of the "Bonnel" type) and independent springs. Both options are very durable, provided that there are a sufficient number of intermediate layers between the block itself and the outer upholstery.

The multilayer coating is prerequisite any high-quality sofa with a spring block.

Dependent spring block

A classic, time-tested option. Here, all the springs are interconnected by a continuous helical steel wire. If you press one spring, the rest will immediately connect to it, thereby distributing the load on the entire base. The structure is attached along the perimeter to the edging frame and is covered with an intermediate layer of non-woven material.

Furniture filled with dependent springs is cheaper, but it should be remembered that the orthopedic properties of a dependent spring block are lower than those of an independent one.. In this case, the springs do not individually adjust to the load, so if another person sits or lies on the sofa (especially with more weight than you) - you can feel how the whole structure sags (the so-called"hammock effect").

Independent spring block

In this type of block, each spring lives its own life and is independent of the neighboring ones, which gives the surface a high point elasticity and allows it to better adapt to the contours of the body.

Placed in separate fabric covers, steel springs do not creak, do not rub, and in case of breakage are not able to break through upper layer filler and cover.

spring snake

Attached to a wooden or metal base with a hinged bar or steel cleats, the serpentine is a simple and inexpensive spring base. And although it is not a full-fledged filler - a layer of polyurethane foam is always laid on top - it is able to withstand heavy loads, does not deform and is very durable.

PPU

Polyurethane foam (PPU or furniture foam rubber) is an inexpensive and highly elastic furniture filler. Provides a comfortable fit, has good elasticity and is environmentally friendly.

For the basis of a sofa with such filling, as a rule, block furniture foam is used, cut and twisted in a certain way. Some models require special blanks molded polyurethane foam, which is also used as a filler for pillows - the material allows you to keep any shape given to it.

The filling of sofas with PUF can be of various brands - standard, PU foam of increased comfort, PU foam with memory effect, etc. The higher the properties of the material, the more expensive the sofa will cost to manufacture.

If you love comfort as much as economy- pay attention to the filler of the sofa - high-comfort polyurethane foam (artificial latex). Its basis is polyurethane foam of especially high elasticity.

Viscoelastic polyurethane foam is a separate type of polyurethane foam that has a unique orthopedic "shape memory" effect. A mattress or pillow stuffed with such material reacts to pressure and heat, remembering the shape of your body. Press down on the surface with your palm and release - the dent will disappear very slowly.

Before buying a sofa or mattress, be sure to find out the density level of PPU- a seat with an indicator of 28-30 kg / cubic meter will provide not only convenience, but also the durability of soft furniture elements. At the backdensity must be at least22-25 kg/cu.m., and armrests- 20-22 kg/cu.m.

Other materials

Furniture fillers are not limited to foam rubber and springs - other materials are used as additional layers for filling.

natural latex

The basis of natural latex is often used in expensive upholstered furniture - the material has high elasticity, instantly restores its original shape, is non-toxic, hypoallergenic and has a long service life.

Sintepon

The most inexpensive, but very resistant artificial filler. It creates extra softness and elasticity. Also, the material is not susceptible to the formation of fungus. The main disadvantage is that with regular use it does not keep its shape, characteristic dents and irregularities appear on the surface. When permanent use this material should be considered in combination with polyurethane foam as a flooring layer - its share in the filling is small, but one way or another it is able to improve the cushioning properties of the seat.

Holcon (strutoplast)

Modern nonwoven fabric, consisting of an intermediate layer of vertically laid synthetic polyester fiber and two covering layers of dense reinforcing ribbed surfaces. This way of laying allows the mattress or pillow to sag only in places of pressure and quickly restore its shape.

Holcon is easy to care for, retains heat well, has increased elasticity, is environmentally friendly and does not absorb moisture and odors.

An unambiguous answer to the question, which better filler for the sofa, does not exist, but you can protect yourself from inconvenience and disappointment by choosing the "stuffing" for the purpose of the future sofa. Yes, for bed it is better to consider a filler with a more rigid and flexible base (highly elastic polyurethane foam, independent spring block, natural latex), because. regular rest on an overly soft or crumpled bed can have a bad effect on the spine. But the guest option provides for any content.
