The design of laboratory chairs needs to consider the requirements of ergonomics and experimental environment. It should have the characteristics of comfort, durability, adjustability, and height flexibility to adapt to different heights of experimental tables and long-term work needs. Laboratory chairs are usually equipped with height adjustment functions, which can be adjusted according to the needs of the experimenter to ensure a comfortable sitting posture and reduce fatigue from long-term work. In addition, some advanced laboratory chairs are equipped with rotation and tilt functions, increasing the flexibility of work.
