Why do you get back pain when you sit in a chair for a long time?

I believe that everyone in the daily office will encounter a problem, office chair sitting for a long time waist pain, of course, this is inevitable, after all, these office workers are basically inseparable from it for about 8 hours a day. So if it can't be avoided, is there a way to mitigate it? Yes, I have! Only two functional designs on the chair can greatly relieve the stress on the waist.

First, the curved cushion. When sitting, more than 75% of the weight of the human body is concentrated on the cushion and the tail vertebrae here, so if you want to do something comfortable, increase the contact surface of the buttocks and thighs to share the support

Second, lumbar support, people in standard sitting posture, lumbar stress is about 1.5 times standing; The waist force of sitting posture is 2 times that of standing, how to do? I recommend lying down, not to brag, I have with this position, got three companies resignation letters

Joking, waist support is mainly to correct your sitting posture to the standard sitting posture, the maximum allocation, reduce the force of the waist, so that the lumbar stress close to the standard standing position.
