Operating Instructions
The FLEXISPOT OC4 Lite chair offers multiple adjustment points to customize your seating experience for optimal comfort and support.
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. Pull the lever up while seated to lower the seat, or pull it up while standing to raise the seat. Release the lever at the desired height.
2. Tilt Function and Tension Control
The chair features a tilt function allowing the backrest and seat to recline together. Use the lever on the left side beneath the seat to lock or unlock the tilt. The tilt tension knob, located at the front center beneath the seat, can be rotated to adjust the resistance of the tilt mechanism.

5. Flip-Up Armrests
The armrests can be flipped up to allow the chair to be pushed closer to a desk, saving space. To flip them up, lift the armrests until they lock into the vertical position. To return them, gently pull them down.
