When people sit on auditorium chairs, they are entirely supported by the seat cushion, which is mainly made of sponge. Today, we will learn about the knowledge of auditorium chair seat cushions from three aspects: the common problems of auditorium chair seat cushions, the production process of seat cushion sponges and the structure of seat cushions!

1. Common problems with auditorium chair seat cushions:

A common problem with auditorium chair seat cushions is that the seat cushions collapse. After you sit down, the seat cushions will dent and will not automatically recover. Many people think that this is damage to the seat cushions caused by spring fatigue. In fact, it is not. Most of the real reasons are: seat After long-term pressure, the elasticity of the cushion sponge is weak. This is partly because the quality of the foam is too poor. It easily loses elasticity and cannot provide effective support pressure.

2. The production process of sponge for auditorium chair seat cushions:

First, what is a sponge? Sponge is made by mixing an appropriate amount of polyurethane and foaming agent. It is put into a closed mold and the foaming agent causes a reaction, causing the resin to expand and fill the mold cavity. After the reaction is completed, it is taken out to become a sponge. The production of the sponge will determine the final quality of the sponge. The sponge has high density, better elasticity, long-lasting pressure resistance, and softness that can fit closely and comfortably with the body.

3. Structure of auditorium chair seat cushion:

The first layer is silk cotton, which can isolate the moisture and moisture transmitted from the fabric, preventing moisture from damaging the base sponge. The second layer is soft high-density sponge, providing the rider with a comfortable and fitting feeling. The third layer is hard high-density sponge, which is elastic and firm.
