Office Chair with Rotation and Elevation Functions

There are various types of office chairs with rotation and elevation functions, as detailed below:

1. Ergonomic Chairs
Represented by the JD.COM Z5 Pro ergonomic chair, its core features include a "flexible rotating lumbar support" and an "adjustable backrest height". The lumbar support allows for 20° of flexible rotation, dynamically adjusting the support angle according to changes in sitting posture. The backrest is equipped with a 50mm elevation adjustment range, enabling users to precisely position the support point based on their height or sitting posture needs, creating a personalized comfort zone. This design achieves its functions through mechanical structures without requiring electric power, making it suitable for long-term office use, especially for users who need precise lumbar support.

2. 3D Dynamic Lumbar Support Elevation and Rotation Chairs
These chairs are characterized by "multi-dimensional adjustment", with the lumbar support section allowing for both forward-backward and up-down adjustments. Some high-end models even offer dynamic fitting in three-dimensional space. Their core advantage lies in the "automatic adaptation" function: through elastic materials or mechanical linkage devices, the lumbar support can automatically adjust the support force and position according to the user's body shape (such as waist circumference and spinal curvature) or changes in sitting posture (such as leaning forward or backward), reducing the frequency of manual adjustments. The elevation function is achieved through gas springs or mechanical elevation columns, with a height adjustment range typically of 10-15cm, accommodating different desk heights.

3. Office Swivel Chair Series
Office swivel chairs are the "basic models" with rotation and elevation functions, covering subcategories such as executive chairs, mid-back chairs, and staff chairs. Their rotation function is realized through a five-claw base with swivel bearings, allowing for 360° free rotation. The elevation function relies on gas springs, with height controlled by pressing the adjustment lever beneath the seat, typically offering a 40-50cm adjustment range. These chairs have a simple structure and low cost, widely used in general office settings. However, their lumbar supports and headrests are usually fixed designs, providing relatively weak support.

4. Reclining Office Chairs/Lunch Break Chairs
These chairs add a "reclining" function on the basis of rotation and elevation, with some models equipped with a one-touch electric adjustment system. For example, some executive chairs use motor-driven adjustment to achieve synchronized adjustment of the backrest angle (90°-180°) and footrest, while also supporting height and rotation functions. Manual models control the backrest tilt angle through mechanical latches, with the elevation function still relying on gas springs. Their design caters to both office and lunch break needs, suitable for users who need short rests. However, they are relatively bulky and take up more space.
