Which is better, the mesh cushion or the sponge cushion of the ergonomic chair?

What dimension does this come from.
For example, 1. When we eat some indigestible food, it is inevitable that some gas will be produced in the body. When it is released from the bottom, it will be reflected whether the mesh cushion or the sponge cushion is better. For mesh cushions, the gas quickly diffuses downward through the mesh and then slowly disappears; while for sponge cushions, the released gas cannot penetrate, and can only spread around or even upward. When your colleagues pass by, there may be embarrassing scenes.
2. The mesh cushion is very breathable and not easy to breed bacteria; while the sponge is not breathable, once sweating, bacteria are very easy to breed.
Overall, I'm still very much leaning toward mesh cushions.
Of course, when choosing an ergonomic chair, the mesh cushion is only one of the references for choosing an ergonomic chair. In addition to the quality of the mesh cushion and the curvature of the spine, it depends on whether the back design of the chair can better protect our body. Waist, including whether you can lie down on a chair to rest and relieve fatigue.
Whether we often sit in the office for a long time, or sit in front of the computer at home and play games for a long time, a good ergonomic chair is really important. Sitting in the wrong posture for a long time will cause great damage to the spine, cervical spine, and shoulder spine.·
