Ergonomic Chair: 8 Adjustments You Need
1. Seat Height
Feet flat on floor, thighs parallel. Knees at 90 degrees. Hips slightly above knees.
2. Seat Depth
Leave 2-4 inches between seat edge and back of knees.
3. Lumbar Support
The curve should sit at your lower back (L3-L5 vertebrae). Adjustable height and depth.
4. Backrest Recline
Slight recline (100-110 degrees) reduces spinal pressure.
5. Armrest Height
Arms at 90 degrees, shoulders relaxed.
6. Armrest Width
Adjustable width lets arms hang naturally.
7. Headrest
Position at the base of your skull, not pushing head forward.
8. Tilt Tension
Adjust resistance so reclining requires light effort.
