Description

Technical Field

[0001] This utility model relates to the field of seating technology, specifically to a high-position work seat. Background Technology

[0002] In hospital or advanced laboratory work environments, there are many times when staff cannot adjust the height of their chairs precisely by hand and often need a second person to help them.

[0003] In the past, hydraulic lifting devices were used to solve this problem. However, when the hydraulic device was raised, the operator had to step on it forcefully, which affected the stability of the operator's hands and eyes. When lowering, the speed was too fast and could not be effectively controlled or finely adjusted. Moreover, the original chairs were mostly flat designs, and sitting for long periods of time could easily lead to fatigue and occupational diseases.

[0004] Therefore, we propose a high-position work chair. Utility Model Content
