Staff, Office, and Adjustable Chairs
Staff chairs, office chairs, and adjustable chairs are office seating equipped with rotation and height adjustment functions, belonging to the category of office supplies. The following provides an introduction from the aspects of definition, functional features, design principles, and applicable scenarios:

Definition: Staff chairs, office chairs, and adjustable chairs are essentially different names for the same type of office seating. They are specifically designed for office environments, aiming to provide users with a comfortable sitting experience and improve work efficiency.
Functional Features:
- Height Adjustment Function: Most office swivel chairs adjust their height using a pneumatic rod. Users can easily adjust the seat height according to their own height and the height of the office desk, allowing their feet to rest flat on the ground and their thighs to be parallel to the ground, maintaining a correct sitting posture. For example, the Saigu Apollo X3 ergonomic chair has four levels of lumbar support height adjustment and four levels of backrest height adjustment; the JD.COM Z5 Pro ergonomic chair has a 50mm adjustable backrest.
- Rotation Function: Utilizing elastic brackets and wheels, it enables rotation buffering and movement locking functions, facilitating users to move freely and turn around within the office area without frequently getting up, enhancing office flexibility and efficiency.
- Adjustability: In addition to height adjustment and rotation functions, these chairs also have other adjustable components. For instance, the lumbar support, backrest, and frame of the Saigu Apollo X3 ergonomic chair adopt a suspended modular design, allowing each part to be adjusted separately or in unison; the JD.COM Z5 Pro ergonomic chair comes with a 3-level lumbar support mode, and its wide lumbar support not only supports the lower back but also protects the sacrum; the headrest of the Sihoo ergonomic chair M56 can be adjusted in height.
Design Principles: The design adheres to ergonomic principles, maintaining the natural physiological curvature through adjustable lumbar support, armrests, and headrest support. Reasonable seat design can disperse body pressure, reduce fatigue and injury caused by prolonged sitting, and protect spinal health.
Applicable Scenarios: Not only suitable for office environments but also for home and medical settings. At home, they can be used as study chairs or computer chairs; in medical settings, they can provide comfortable sitting support for healthcare workers or patients.
