Description

Disconnect-type air fiber waist leans on

Technical Field

The utility model relates to the field of furniture, concretely relates to disconnect-type air fiber waist leans on.

Background

If the person stays in front of a computer for a long time in an improper sitting posture, the back and the back of the person are easy to fatigue, and muscles of the back and the back of the person are easy to pain. At present, there are also many waist support products in the market, such as sponge waist pillow, back cushion or car waist back, back rest etc. but these products exist in the gas permeability relatively poor, and the support to user's waist is not enough, moreover in the use shortcoming such as comfortable inadequately for user's experience sense greatly reduced.

Currently, lumbar supports are commonly available on the market, either made of all-sponge, spring, or latex. The sponge is made of full sponge, and after the sponge is used for a period of time, the resilience of the sponge is poor, and the phenomenon of concave collapse is easy to occur.
