It depends on how comfortable you will be. Now there are a lot of fillers, it is necessary to have an idea about some, about their quality, quality factor, how much furniture with such a filler can serve.

Types of fillers for upholstered furniture

Furniture manufacturers more often use polyurethane foam - PUF as a filling. Many sofas with spring unit. Buyers are sometimes lost, which is better - a spring or PPU and can not make a choice.

How does it work

Filler - polyurethane foam for orthopedic mattresses and upholstered furniture

Before choosing a sofa, we learn what PPU is. This is a synthetic porous substance consisting of cells filled with air. In its manufacture, the liquid composition foams, then solidifies. Polyurethane foam is 90% air, has thermal insulation properties. PPU - the same foam rubber, is used almost everywhere - as a filler for furniture, from it toys for children, sponges for dishes, washcloths and much more are made.

Foam sheet for softness

As a filler, it is widely used due to compaction, this property gives softness and elasticity to the product. It is produced in the form of small sheets - this is foam rubber, and also in the form of rather strong and massive plates - these are polyurethane foam. If the material is of poor quality, it will quickly become unusable and will crumble. Then it needs to be replaced.

Advantages and disadvantages

Elastic polyurethane foam is used in the furniture and automotive industries

Polyurethane foam has pros and cons. Consider the positive properties.

1. The main quality is that dust does not accumulate in it, it is completely hypoallergenic. This ability is important for those who are prone to allergies.
2. In the manufacture of it is treated with antibacterial and antifungal agents, so it does not harm health.
3. It can last a long time, has wear resistance.
4. It has good breathability.
5. Thanks to elasticity instantly restores its original shape.

There are also negative properties

1. PPUs of poor quality often come across - it will lose its original shape in a short time, and the furniture will quickly sag.
2. The material does not tolerate direct sunlight, begins to deform. In the manufacture of using upholstery made of lightproof materials.
3. Polyurethane foam - a highly flammable substance, emits toxic substances when burned.
4. For many, the high density of PUFs may seem solid.
5. Excessive softness of the material can cause back problems, and in children - curvature of the spine, so they are better off sleeping on a hard surface.

Polyurethane foam or spring block? What is the best filler for a sofa?

Upholstered furniture based on an independent spring block

Enough time has passed, when spring blocks were replaced by materials that are used as a filler for upholstered furniture - these are latex, holofiber, polyurethane foam, synthetic winterizer. But what is better - a spring block or polyurethane foam?

No one will answer the question "What is better?" Each filler has advantages and disadvantages. What you prefer is up to you.

The best springless synthetic fillers

• Many furniture manufacturers prefer to use polyurethane foam, as it is an affordable material and is easy to work with. There are two types - cast and block. In the first case, special forms are filled with the necessary composition, similar in thickness to sour cream. After it hardens, the desired shape will be obtained. In the second case, the sheets are cut into layers of the required thickness and size and glued together.

• Synthetic fluff. The spiral-shaped fiber made of silicone restores its former shape after compression in a matter of minutes. It has properties such as quality factor, reliability. It is mainly used for stuffing pillows for furniture, as a filler for backs and armrests.

Synthetic fluff - the artificial material of the future

• Synthetic winterizer. Non-woven, very lightweight material made from polyester fibers. The substance is hypoallergenic, therefore furniture with a synthetic winterizer as a filler is used in children's rooms, suitable for people prone to allergies. They are also stuffed with pillows, used in the manufacture of clothes. Eco-friendly material, does not wear out for a long time, is resistant to various fungi, has a water-repellent property, is safe.

Sintepon - a material suitable for people with allergies

• Periotek. It looks like weightless chubby felt, safe for allergy sufferers, and may contain fibers of wool or cotton. The density of such furniture can be ordinary or high.

The best springless natural fillers

Any filler that is used in the manufacture of upholstered furniture or mattresses has its own properties.

• Natural latex. It is made from rubber tree juice using individual technology. It is foamed, as a result of which cells are formed, therefore it “breathes”. Excellent heat and moisture conductivity, solid material, very high quality. Shelf life is approximately 10 years. Instantly takes its former shape after heavy loads. There is only one drawback - a very high price.

Latex mattress - high quality, comfortable and safe

• Horsehair. Great filler. Horse mane is treated with latex. This is done so that the material is elastic and lasts for a long time, moisture resistant, breathable. High quality filler, but expensive. Not suitable for people prone to allergies.

Horse hair for upholstered furniture and mattresses

• Coconut Coir. They produce fibers from the inter-fruit of coconut; they, like horse hair, undergo latex treatment so that they are elastic and strong. In addition, they also have antibacterial properties, are hypoallergenic, environmentally friendly, not subject to decay, breathing material. Furniture with such a filler is perfect even for young children.

• Sea grass. The most environmentally friendly filler. In the manufacture of raw materials combined with jute. Furniture has sufficient rigidity, which is favorable for the back and maintaining the health of the spine. In addition, such a filler strengthens the immune system, normalizes sleep, as it contains iodine and various minerals.

How to choose the right PPU filler. What is it on the couch

High-quality and durable PPU fillers

Not every PPU is of good quality. Only excellent polyurethane foam has the necessary properties. Do not make the difference between foam rubber and PPU - these are materials identical to each other. The difference is in function, cost, properties, category. Before choosing furniture, be sure to check its density - it should be from 30 kg / m3. Accordingly, the higher the density, the higher the quality and cost.

Sofa with PPU filling on the frame

Do not lose sight of the thickness of the material. The normal rate is four centimeters. It happens that in order to save money they use a filler 3 or 2 cm thick. It is better to ignore furniture with a filler of this thickness. How elastic and hard the sofa is depends on your personal preferences. The choice is always yours.

What is it: classification of fillers

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

In the first case, several layers of natural or artificial coating material — coconut coir, latex, foam rubber, felt, etc. — are laid on cylindrical springs or the base of a spring “snake”. Different densities of this or that coating and many options for springs make it possible to create fillings of different degrees of rigidity.

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

Spring snake

Simple and inexpensive spring base

The spring block snake is also a type of filler. It is often used in the furniture manufacturing industry, including for sofas. It is used in soft elements, mainly in the seat, back.

Springs made of galvanized metal and fastened in the transverse direction to the wooden base of the sofa with hinged slats or clips. Their number depends on the size and purpose of the product. The base of the structure is composed of these springs. The top is then covered with a layer of felt, batting or foam.

A spring snake lets air through well, therefore possible moisture will evaporate and the product will dry quickly.

The seat is obtained with a spring effect, quite soft. It is not resistant to heavy loads. After a short time begins to bend. This is a big minus for sofas with such a filler, which not recommended for frequent use and not suitable for sleeping.

Natural latex

Ideal for all sleep products.

Natural latex is made from rubber of natural origin. Rubber in its pure form is very moody, so it is supplemented with an inhibitor.

The material is widely used in furniture filling. The share of rubber in such fillers should be in the range of 45-65% so that it possesses the necessary qualities:

• elasticity
• elasticity
• wear resistance

Natural latex is one of the best fillers. It has unique properties.

• Due to the high level of elasticity, it supports the body well, eliminating unnecessary swaying and vibrations. Recovers very quickly
• The structure of latex gradually adapts to the contours of the body, reacts even to light pressure. This makes it very comfortable, allowing you to support those parts of the body that need it: neck, head, lower and upper back, spine
• The porous structure passes air well, which does not allow moisture to accumulate in the filler itself
• It has good thermoregulation: in winter it keeps warm, in summer it gives coolness
• The high quality and durability of latex makes the filler durable in operation, little prone to deformation.
• The material is hygienic and hypoallergenic.
• Filler is absolutely silent to use.

• The disadvantage is the high cost of this filler

There is artificial latex - highly elastic polyurethane foam. The main differences of the natural filler: a grayish tint and to the touch it seems greasy.

Synthetic winterizer

Creates extra softness and firmness.

It is an intermediate material. Sinteponom covers the top of the filler. They are also filled with cushions.

Available in various densities. Necessary density indicators for different furniture elements:

• backrest, armrests - 300 g / sq.m
• sitting - not less than 400 g / sq.m
• pillows - more than 300 g / sq.m

It is necessary to strictly observe these indicators. Then the sofa will be soft, outwardly attractive. Will delight with its coziness and comfort.

This material is popular for its properties.

What types of fillers for sofas exist

By the type of filler, all modern upholstered furniture can be divided into two groups - spring and springless. Inside the first type of products, a spring block is installed.Despite the fact that the technology is considered obsolete, spring furniture is still in demand. Springless fillers are blocks of modern synthetic or natural materials with different densities. Such furniture is also popular, as it gives future owners a huge scope in choosing the rigidity of the seat.

Spring fillers for sofas

Spring structures are most often found in antique upholstered furniture and inexpensive modern products. The best filler of this type is an independent spring unit. It is a structure consisting of cylindrical vertically arranged springs. The average diameter of the springs is 5-6 cm. The number of elements per 1 square. m. - 250 pieces. Each spring is placed in a fabric cover, not in contact with other structural elements. To give softness to the seat, the spring block is lined on both sides with soft materials - polyurethane, batting, felt or coconut coir.

Furniture with an independent spring unit is durable and quiet. Often, such a filler is installed in the mattresses of classic beds, since during sleep a comfortable body position is ensured. Independent spring blocks are also equipped with upholstered furniture - sofas, couches, armchairs-beds, which are installed in the children's room, bedroom, living room.

Springless Fillers

Manufacturers also use springless fillers in the manufacture of furniture. Most often, preference is given to polyurethane foam - bulk porous mass, which is obtained by mixing several types of polymers. Most of the volume of the material - up to 98% - is air, so the seats of upholstered furniture are elastic, keep their shape well. The rigidity of the filler varies depending on the type and proportions of the blended polymers. For example, foam is also polyurethane foam, but with a low density. That is why the material is quite soft and supple.

In the furniture industry, cast and block polyurethane foam (PUF) is used. Molded polyurethane foam is also called molded, since in the manufacture of the structure the polymer mixture is poured into a special blank. In size and shape, it corresponds to certain elements of future furniture - seats, back or pillows.

The second name of the block PPU is sheet. When creating the filler, the sheets of material are cut into pieces of the desired thickness and size. After that, the block polyurethane foam is glued together, forming the design of future furniture. Sometimes manufacturers use up to 5-6 sheets of material of different densities when creating upholstered furniture.

Armchairs and sofas are also stuffed with natural latex. The material is foamed juice of the rubber tree of hevea, which grows in tropical countries. Latex has a porous structure, is environmentally friendly and hypoallergenic material. Upholstered furniture filled with latex will last at least 10 years, while maintaining the elasticity of the seats. The only minus of the products is the high price.

Furniture manufacturers also use other soft sofas for sofas to create added comfort and shape individual elements. Most often, preference is given to:

• synthetic winterizer - lightweight non-woven fabric with straight fibers,
• syntepuhu - a natural filler treated with silicone emulsion,
• holofiber - a synthetic fiber in the form of elastic balls that quickly restore shape after crushing.

Sintepon more often stuffed backs of sofas and armchairs. The material provides a soft design and gives a feeling of comfort during rest. Layers of holofiber and sintepuha are placed on top of the polyurethane foam seat, installed in the armrests. Soft fillers of this type are also used in the manufacture of decorative pillows.

What are the pros and cons of fillers worth knowing

Before you buy a sofa in the living room or bedroom, you need to study the advantages and disadvantages of different types of fillers. If this is not done, then after 1-3 years it will be necessary to change furniture due to squeezed seats that have lost the shape of armrests and backs. And this is a strong blow to the family budget and unnecessary nerves.

The advantages of furniture made using Bonnel technology or equipped with an independent spring unit include:

• long service life
• resistance to heavy loads,
• orthopedic effect
• free air and moisture exchange.

Cons sofas also have spring sofas. The first thing that pushes some buyers away is the high price. The second is the creaking of the springs, which may appear after a couple of years of operation. Do not forget about the possible expenses for furniture restoration - replacing the filler in the sofa can result in a decent amount.

Furniture with PPU filler has many times more positive properties. The advantages of polyurethane foam include:

• durability,
• reliability,
• the ability to choose stiffness,
• safety and hypoallergenicity,
• resistance to fungi and mold,
• low cost.

There is only one drawback of such furniture - cheap models with low-quality filler, which quickly loses shape due to low density and is squeezed.

Soft couch fillers also have pros and cons. For example, a synthetic winterizer is rightfully considered one of the cheapest, soft and lightweight materials. It does not cause allergic reactions, does not absorb moisture and is resistant to fungi. Sofas with synthetic winterizer can be installed on the balcony or summer terrace in the children's room.

The only drawback is that over time, the material begins to get lumpy, which negatively affects the appearance of the furniture.

Hollofiber boasts the best performance. The filler will last quite a while, retaining its original shape and elasticity. Sofas and armchairs with such a padding can even be put in the kitchen, as the material does not absorb odors. On upholstered furniture filled with holofiber, it has orthopedic properties, so it is comfortable to sit and sleep on it. The material has no significant minuses.

Sintepuh soft, lightweight and hypoallergenic material. It does not get lumpy during operation, does not absorb moisture, and tolerates washing and dry cleaning. A sofa with such a filler is installed in the kitchen, in the children's room, in the living room.

How to choose the best filler for the sofa

In addition to the type, pluses and minuses of the filler for the sofa, you must take into account such a property as density. Carefully study this option should be before buying furniture with PPU. Most often, sofas and armchairs are filled with polyurethane foam with a density of 30–40 kg / cu. m. If the density of the material is higher, then the seats will be tougher, and the tendency to deformation is less. Furniture with such a filler will last at least 5-7 years. Therefore, after evaluating the appearance of the sofa, you should definitely look into the product passport, where the density of the filler is indicated.

It is generally accepted that furniture equipped with a spring block is durable and reliable. Its average life is 10 years. Spring-filled sofas are installed in the living room or bedroom. Models have orthopedic properties - they provide uniform support for the body over the entire area, they do not creak or push through. After sleep, you will feel rested and full of energy. However, do not forget about the ratio of quality and price - products with such a filler are often very expensive.

High-density polyurethane foam is almost as good as furniture with a spring unit, but it is cheaper. The filler retains its properties for 6–8 years, so it is suitable for daily sleep and rest. Pricing is influenced by brand awareness, as well as the brand and density of PPU. The better and stiffer the filler, the more expensive the sofa will be.

The most expensive soft fillers for sofas are holofiber and sintepuh. Usually they fill decorative pillows, less often - the main structural elements. If in the manufacture of furniture natural materials were used, for example, coconut coir, then the cost of the product will be higher.

The cheapest material is foam rubber. Furniture with such a filler is installed in the kitchen, taken to equip the cottage. The average life of the products is from 3 to 5 years.

Any furniture eventually deteriorates, so do not forget about the need to replace the filler in the sofa. It is better to choose products with removable covers. Such models are easier to care for, and repairs will result in a smaller amount. You can restore furniture yourself, however, it is more advisable to contact specialists.

In order not to waste money, first decide on the purpose of the furniture. Then select a filler that suits the price and quality, evaluate the dimensions, colors of the finishes and decorative elements. This is the only way to buy the perfect sofa that will delight you and your loved ones for a long time, and also will not make a hole in the family budget.

Anderssen factory craftsmen use high-quality fillers in the manufacture of upholstered furniture - polyurethane foam (PUF) and independent spring blocks. Thanks to such materials, sofas and couches acquire orthopedic properties. And soft fillers - hard, bathrobe, synthetic winterizer and periatek - make furniture comfortable. Products from the Anderssen factory will last at least 15 years, turning every minute of relaxation into a true pleasure.

Dependent spring unit

Classic, time-tested option. Here, all the springs are connected by a continuous spiral steel wire. If you click on one spring, the rest will immediately connect to it, thereby distributing the load on the entire base. The structure is attached around the perimeter to the edging frame and is closed by an intermediate layer of non-woven material.

Holkon (Strutoplast)

A modern non-woven fabric consisting of an intermediate layer of vertically laid synthetic polyester fiber and two cover layers of dense reinforcing ribbed surfaces. This way of laying allows the mattress or pillow to slip only at the places of pressing and quickly restore shape.

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

There is no single answer to the question which filler is better for the sofa, but you can protect yourself from inconvenience and disappointment by choosing the “filling” for the purpose of the future sofa. So, for a berth, it is better to consider a filler with a more rigid and flexible base (highly elastic PPU, independent spring block, natural latex), because regular rest in an overly soft or swept bed can adversely affect the spine. But the guest option provides for any content.
