Key Adjustment Definitions
- Synchro-Tilt
- A mechanism where the backrest and seat pan recline at a fixed ratio (often 2:1), allowing the user to recline while keeping their feet flat on the floor.
- 4D Armrests
- Armrests that adjust in four dimensions: height, width, depth (forward/backward), and pivot (angle).
- Seat Depth (Seat Slider)
- The ability to move the seat pan forward or backward to accommodate different thigh lengths and ensure proper circulation behind the knees.
- Lumbar Support (Sacral/Lumbar)
- Mechanical support for the lower spine. Advanced systems may offer height, depth, or firmness adjustments to match the user's spinal curvature.
- Tilt Limiter / Back Stop
- A control that restricts the range of recline to a specific angle, preventing the chair from leaning back beyond a chosen point.
