The softness of the seat surface is suitable to make the ischium support about 60% of the human body weight, so the hardness of the seat surface should be moderate, not too hard or too soft.

Hard chair surface, the ischium directly contacts the chair surface, which will soon lead to ischium pain. You can imagine sitting on a wooden stool.

The whole hip of the soft chair surface has a large contact area with the chair surface, so it is very comfortable to sit at first. Even if you sit sideways, it will easily cause scoliosis after a long time, which requires special attention. In addition, if the chair surface is too soft, it is easy to sink in, and the mesh will hold you back, and then the front end of the cushion will press the thigh and hinder blood circulation. After a long time, it is easy to cause insufficient blood supply to the legs and numbness in the legs.

Therefore, you need a good ergonomic chair that can provide reasonable support for your hips. For example, Paglis's PH-08BH ergonomic chair is made of a flame-proof mesh fabric made of integrated pressed cotton, which has moderate hardness, good resilience and is not easy to collapse. It is not only soft and comfortable to sit on, but also breathable and stuffy. The seat cushion is still an ergonomic saddle shape, which can evenly disperse the pressure on the hips and legs, and even if you sit for a long time, you will not feel tired and numb. Such a good cushion is what we should choose!
