Today we have decided to explain the most important points that you have to take into account when you go to choose an office ergo chair cushion. In particular, this type of chair must be ergonomic. It is recommended for long-term sitting positions, where you can support your back, arms and feet. The posture of the body will be active but without tensions. The chair must have a pneumatic or mechanical system that allows adjusting the height of the chair once the user is seated.
The recommended height should allow the feet to rest firmly on the ground, as well as the thighs to be horizontal. In an ergonomic chair, the ergo chair cushion has to be wider than the hips and legs, so that it overlies in the horizontal about 3-5 cm. You have to feel comfortable when sitting at a wide level.
At the transverse level, the flight of the ergo chair cushion should not be extreme; otherwise, it would collide with the back of the thigh and knee and could cause injuries. A standard ergonomic chair should have a cushion with medium-high density foam padding, since if it is of low density, habitual use will produce deformations in the cushion, so that the cushion loses its ergonomic functions.
