Description

Intelligent lifting office desk and chair

Technical Field

The utility model relates to the technical field of office equipment, and in particular to an intelligent lifting office desk and chair.

Background Art

A common structure of an office desk includes a desk top and legs located below the desk top. Since the height of the legs is fixed, the height of the desk top is also fixed, and the desk cannot be adapted to users of different heights.
