Operating Instructions and Adjustments
The Alera Kempton chair offers several adjustment features to customize your seating experience for optimal comfort and ergonomic support.
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side, beneath the seat.
- To raise the seat: While standing, pull the lever upwards. The seat will rise. Release the lever at the desired height.
- To lower the seat: While seated, pull the lever upwards. The seat will lower. Release the lever at the desired height.
Optimal height allows your feet to be flat on the floor with your knees at a 90-degree angle.
2. Tilt and Recline Adjustment
The chair features a tilt and recline function, allowing for a range of motion.

- To recline: Lean back in the chair. The chair will recline.
- To lock/unlock tilt: Locate the lever on the left side, beneath the seat. Push it inwards to lock the tilt in an upright position, or pull it outwards to allow free tilting.
3. Tilt Tension Adjustment
Adjust the resistance of the chair's recline motion using the round knob located beneath the seat, at the front.
- To increase tension (more resistance): Turn the knob clockwise.
- To decrease tension (less resistance): Turn the knob counter-clockwise.
Adjust tension so the chair supports your back comfortably without pushing you forward or allowing you to recline too easily.
4. Adjustable Lumbar Support
The chair features adjustable lumbar support to maintain correct posture and provide personalized back comfort.

5. Adjustable Armrests
The armrests can be adjusted in height and width to provide optimal support for your forearms and shoulders.

- Width Adjustment: Some armrests may allow for inward/outward adjustment. If applicable, loosen the knob or lever beneath the armrest and slide it to adjust width, then re-tighten.
Adjust armrests so your elbows are at a 90-degree angle when typing, with shoulders relaxed.
