Product Information

Description

The ON-22 is a full mesh ergonomic chair built for long hours at the desk. Complete mesh across the seat, backrest and headrest keeps airflow consistent throughout the day, while 3D adjustable lumbar support lets you dial in the exact position your lower back needs. The headrest adjusts in height, angle and depth, and detaches entirely if you prefer a cleaner look.

With height-adjustable armrests and a multi-function tilt with three lock points, the ON-22 adapts to how you work, not the other way around. Recommended for users between 155 and 205cm, with a 136kg weight capacity.

Key Features

✓ 3D Adjustable Lumbar Support – Fine-tune the height, angle and depth to position exactly where your spine needs it, preventing lower back pain during extended work or gaming sessions

✓ Full Breathable Mesh Construction – Complete mesh across headrest, backrest, and seat prevents heat buildup during long sessions, keeping you comfortable and focused hour after hour

✓ 3D Adjustable Headrest – Configure the height, angle, and depth so your head and neck stay properly supported whether you're sitting upright for work or reclined during breaks. Detaches easily if you prefer a cleaner backrest profile.

✓ Height-Adjustable Armrests – Adjusts to support your arms at the proper 90° angle, reducing shoulder and neck tension during keyboard and mouse use

✓ Multi-Function Tilt with 3 Lock Points – Lock upright for focused work, or fully reclined for breaks. Adapt the chair to whatever you're doing.
