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 freezes. Polyurethane foam for 90% consists of air, has thermal insulation properties. PPU is the same foam rubber, it is used almost everywhere - as a filler for furniture, toys for children, sponges for dishes, sponges and much more are made of it.
Foam sheet to give softness to the products
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 - it is foam rubber, and also in the form of rather strong and massive slabs - these are PU 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 industry.

Polyurethane foam or spring block? Which filler for the sofa is "better"?
Upholstered furniture based on independent spring block
Enough time has passed, when materials that are used as a filler for upholstered furniture replaced the spring blocks - these are latex, holofiber, PPU, and synthetic winterizer. But what is better - a spring block or polyurethane foam?
Filling a sofa-accordion on a metal frame
| Comfort | This property is important for any furniture, no matter what function it performs. It is important when you lie so that the pits do not appear, then it’s definitely not a rest, and instead of a restful sleep you will look for a comfortable position. The load must be distributed equally on all bases. What can be said about PPU? It keeps its shape well, is distinguished by excellent elasticity, it adapts to the contour of the human body. Maintains a lot of weight, instantly takes the original look. If the material is of sufficient quality, it will serve for a long time. |
| Spring blocks | There are dependent and independent. In the first embodiment, the springs are interlaced with each other and have long been out of use. On such a basis it is simply unbearable to lie, if you press on one spring, it will pull all the others. The second option allows you to relax perfectly, in such blocks each individual spring is packed in a bag, the load in this case is evenly distributed. |
| Thoroughness. | Undoubtedly, PPU is a durable material. It does not accumulate dust, excellent breathability, it is harmless. Furniture with such a filler will serve more than one year, if you use it for its intended purpose. But if you often jump on such a sofa, which children especially like to do, then it will quickly lose elasticity.
The same applies to the spring blocks, not everyone can withstand such loads, especially an inexpensive option. The economy class furniture will creak, and the springs will come out through the upholstery. In high-quality sofas between the spring block and upholstery put a sufficient number of intermediate layers, so the springs always remain in place. |
| Price. | Furniture with spring blocks is more expensive than with polyurethane foam. But it all depends on the quality of the material. So think carefully before you buy a sofa cheaper, otherwise the joy of buying will result in big problems. Be sure to ask the seller what kind of filler inside, what quality. After all, it depends on how long the furniture can last for you, whether it will be comfortable, comfortable to sit or sleep on it, so that the original look remains the same as long as possible. |

Not every PPU has good quality. Only excellent polyurethane foam has the necessary properties. You should not make a difference between foam rubber and PU foam - these are identical materials. The difference lies in the function, cost, properties, categories.Before choosing furniture, be sure to ask about its density - it should be from 30 kg / m3. Accordingly, the higher the compaction, the higher the quality and cost.
