Sofa Filler
Aug 08, 2017

There are three main types of sofa fillers:

A, soft polyurethane foam (commonly known as sponge): The sponge used for sofa filling is mainly divided into three categories: conventional sponge is a conventional polyether and TDI for the main production of sponges. The characteristic is has the good resilience, the softness, the air permeability; high rebound sponge is a kind of active phosphorus and TDI as the main body of the sponge, its characteristics have excellent mechanical properties, good elasticity. Large compression load, flame resistance, good air permeability; porous sponge is a kind of internal pores by the size of natural seaweed similar to a sponge, its characteristics are good elasticity, compression, rebound with excellent cushioning.

B, down filler: down do sofa filler, comfortable sitting, long use deformation small, the disadvantage is rebound slow, cost is high. Generally in the advanced sofa with the use of sponges, or suitable for cushion use.

C, man-made sponge filler: man-made cotton sofa filler, soft excellent, comfortable sitting, but poor mechanical performance, compression load small, only suitable for cushion.  Sofa Filler Selection point: Depending on the type of filler, there is a big difference in the use. In general, fabric sofa cushion filler should use 30 kg/cubic meters above the high rebound sponge is more appropriate, in the form of most of the whole sponge filled by the way, the best way is to use 30 kg/cubic meters of high rebound sponge and hole sponge combined with feather or artificial cotton overlay to increase the comfort and service life. Choose to ask the type of filler, if the filler is a sponge to understand the density of the sponge used, using gravity to feel the rebound effect of cushion, sitting on the feeling of comfort and so on.

General use sponge cushion, national standard 25KG/M3, International standard 35KG/M3. The bottom structure, the high elastic snake spring structure is superior to the bandage structure, the high-quality bandage is better than the inferior bandage structure, after the long time compression can still rebound quickly, restores intact, does not deform, does not collapse.
