Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

The 360-degree rotary folding chair shown in fig. 1 to 3 has a chair body, the chair body comprises a supporting seat 3, supporting legs 4 and a backrest 1, the supporting legs 4 are arranged below the supporting seat 3, and the backrest 1 is connected to one side of the supporting seat 3.

In this embodiment, back 1 rotates with supporting seat 3 to be connected, and back 1 can follow supporting seat 3 and rotate the book of turning over that realizes back 1 promptly, and back 1 comprises arc branch 2, and the position that the upper end of arc branch 2 is close to neck portion is provided with the curve arc unanimous with human neck contour, and aim at makes back 1 and human perfect laminating, and back 1 provides even supporting force to the neck to improve the comfort that the user leaned on.
