High-back mesh office chair

The SIHOO M18-014 is a new ergonomic office chair built with a steel frame and breathable mesh upholstery in black. It supports users up to 331 lbs and features an S-curve backrest designed to follow the spine. Adjustable lumbar support, headrest, and armrests allow personalised positioning for long desk sessions.

Three-position recline limit

The backrest locks at three fixed angles between 110° and 126°, so continuous tilt tension or infinite recline positions are not available. Seat height adjusts from 16.9 to 20.8 inches, which may not suit very tall or very short users without a footrest. The mesh backrest and fabric cushion prioritise airflow over plush padding.

331 lbs weight capacity

This single figure determines whether the chair matches the intended user. The steel frame and oversized waterfall sponge cushion are rated for this maximum load. Buyers who need a higher rated capacity should look elsewhere.
