Description

technical field [0001] The present invention relates generally to a chair, and more particularly, to a chair in which the heights of the seat and backrest can be adjusted independently. Background technique [0002] As is generally known, various types of chairs are used depending on the desired purpose of the chair. Chairs are typically divided into coaches and armchairs.

Problems solved by technology

Thus, the user's weight is not stably supported, and moments act on the corresponding joints, thus causing damage to the components

[0007] Further, the problem of the conventional chair is that the joint structure of the parts is quite cumbersome and complicated, thus resulting in high product cost
