Seat cotton generally use 25~28kg/m5, the other uses 20~22kg/m3 density. A fireproof sponge material is sponge, sponge foam, add fire retardant materials, such as chlorine and bromine to sponge fire can produce fire smoke, the fire retardant effect.

This material by setting cotton: cotton polyurethane material, the foaming agent and other additives, pressure agent into simple mold heating can form different shapes of the sponge, it is suitable for chairs, sofa cushion, cotton back, a small handrail is made of cotton with stereotypes. At present, the density of materials used for 55#~60#, its elasticity is more in line with national standards.
