2.1 Seat Height Adjustment
To adjust the seat height, locate the lever typically found under the right side of the seat. While seated, lift the lever to raise the seat. To lower the seat, lift the lever while applying weight to the seat. Release the lever at the desired height.
2.2 Auto-Fit Tilt Mechanism
The T25 features a patented (Patent No. 01-2012-7029858) weight-activated auto-fit tilt mechanism. This system automatically adjusts the tilt tension based on your body weight, providing optimal recline support without manual tension adjustments. Simply lean back to engage the tilt.
2.3 Tilt Lock
The backrest can be locked into different sitting angles. Locate the tilt lock lever, usually near the seat height adjustment. Engage the lever to lock the backrest in your preferred position, or disengage it for a perfectly flowing recline.

The T25 chair is equipped with fixed armrests, positioned to comfortably support users. These armrests are not adjustable in height or position.

The high-quality casters are designed for smooth movement across hard floor surfaces. Ensure the floor is clear of obstructions for optimal mobility.
