A Filler For A Sofa

- Sep 27, 2017-

There are three main kinds of padding for sofa:

A, soft polyurethane foam (commonly known as sponge): sponge used for sofa filling, mainly divided into three categories: conventional sponge is a regular polyether and TDI as the main body of the sponge. The utility model has the advantages of good resilience, softness and breathability; the high resilience sponge is a sponge generated by active phosphorus accumulating and TDI as the main body, and has the advantages of excellent mechanical property and good elasticity. The utility model has the advantages of large compression load, good combustion resistance and good air permeability; the irregular hole sponge is an inner hole with different sizes of natural algae similar to a sponge, and is characterized by good elasticity, excellent cushioning property when compressed and rebound.

B, down filling: down to do sofa filling, comfortable sitting, long-term use of small deformation, drawback is slow rebound, high cost. Generally used in conjunction with the sponge in the advanced sofa, or suitable for cushion use.

C, artificial padding: artificial cotton sofa filling, soft and comfortable, comfortable seat, but poor mechanical performance, compression load is small, only cushion. Sofa filling point of choice: depending on the type of filler, there is a big difference in the use. In general, sofa cushion filling should be 30 kg / m3 high rebound sponge is appropriate, in the form of most of the sponge filling mode is the best form of 30 kg / m3 high rebound sponge and sponge down with chaos or artificial cotton with increasing comfort and the use of superposition life. When choosing, ask the type of filling. If the filler is a sponge, you should know the density of the sponge used, feel the cushion effect of the cushion with gravity, and sit on the comfort of the feeling of sitting and so on.

General use of sponge cushion, national standard 25KG/M3, international standard 35KG/M3. The structure of the high elasticity snake spring is better than the bandage structure, and the quality bandage is better than the inferior bandage structure, and can rebound rapidly after a long time compression, and the original shape is restored without deformation or collapse.
