Abstract
A base coupling structure of a height adjustable chair, using a sleeve to connect an oil cylinder and a foot support of a height adjustable chair, the sleeve and the oil cylinder can be tightly embedded together by taking the advantages of having slightly different taper sizes and different elasticity of materials, and the sleeve is coupled with the foot support by a screwing base structure which can be dismantle, so the present invention not only can enhance the speed of the replacing the used oil cylinder, but also can protect the foot support from being damaged and allow a reduction in service cost of the height adjustable chair.
