High-grade sofa cushions should use high-elastic foam sponges with a density of 30kg/m 3 or more, and high-elastic foam sponges with a density of 25 kg/m 3 or more should be used for the back cushions.
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 cushions, so that the sofa has higher resilience and anti-aging properties.
Under normal circumstances, it is best to have a sofa cushion of about 10 cm after sitting down. Finally, if the sofa has foam, it must be filled with cotton or polyester to ensure comfort and no deformation.
