Foam sponge

- Feb 20, 2019-

High-grade sofa cushions should use high-elastic foam sponges with a density of 30 kg/m3 or more. The back cushions should use high-elastic foam sponges with a density of 25 kg/m3 or more. In order to improve the comfort of sitting and lying, some foams are soft-treated under the premise of ensuring no reduction in density, and some are provided with vertical springs in the seat cushion, so that the sofa has higher resilience and anti-aging properties. Under normal circumstances, it is best to have a sofa cushion with a depression of about 10 cm after sitting down.
