Stepless Reclining Office Chair

The Stepless Reclining Office Chair is an ergonomic chair with multi-dimensional adjustment functions, suitable for both work and rest scenarios. Its core design revolves around the support needs of the human body in different postures, with the following specific features:

Backrest Adjustment Function
This office chair supports stepless adjustment from 95 degrees to 160 degrees, covering all scenarios from focused work to deep rest. The 95-degree to 120-degree range is suitable for office scenarios, allowing users to slightly recline the backrest to disperse back pressure and avoid muscle tension caused by prolonged upright sitting. The 120-degree to 160-degree range is designed for rest scenarios, with the 160-degree flat-lying mode enabling the body to be in a near-horizontal position, supported by a headrest to effectively relieve spinal pressure and simulate a sofa-like relaxing experience. The stepless adjustment design allows users to precisely control the angle according to their own comfort, avoiding the inadequate adaptability caused by fixed gears.

Lumbar Support Adjustment Function
By turning the black knob on the side of the chair, users can adjust the height of the lumbar support within a 6-centimeter range. This design is based on the physiological curvature of the human spine, enhancing the fit between the waist and the backrest by dynamically adjusting the position of the lumbar support. For example, taller users can move the lumbar support up to the third lumbar vertebra position for targeted support; during prolonged office sitting, appropriately lowering the lumbar support can disperse pelvic pressure and reduce waist soreness caused by a fixed sitting posture. The convenience of the adjustment process (one-handed operation) further enhances the user experience.

Seat Depth Adjustment Function
The 5-centimeter seat cushion depth adjustment function can accommodate the leg lengths of users with different body types. When the seat depth is shallow, an appropriate gap is maintained between the front of the thighs and the edge of the seat cushion to avoid compressing the blood vessels behind the knees; when the seat depth is increased, the seat cushion can fully support the thighs, reducing fatigue caused by leg suspension. This function is particularly suitable for users who need to alternate between upright and forward-leaning sitting postures, allowing them to quickly switch work modes by adjusting the seat depth while maintaining full contact between the buttocks and the seat cushion.

Footrest Linkage Design
The footrest forms a linkage mechanism with the backrest angle adjustment: when the backrest reclines, the footrest automatically extends synchronously to form a continuous support surface; when the backrest returns to an upright position, the footrest automatically retracts. This design ensures that users can naturally place their arms on the armrests regardless of whether they are in a sitting or lying position, avoiding arm suspension or posture distortion caused by independent operation of the footrest. The linkage mechanism also simplifies the operation process, eliminating the need for users to adjust the backrest and footrest separately and improving usage efficiency.
