Best-in-class ergonomic comfort at a budget-friendly price. The Sihoo M18 combines breathable mesh, a soft W-shaped cushion, and adjustable lumbar support for everyday work comfort.

The Sihoo M18 Ergonomic Office Chair delivers a supportive, highly adjustable seating experience designed for long hours of focused work. With sculpted lumbar support, a removable headrest, and cushioned comfort, the M18 helps promote healthier posture at home or in professional settings.

The contoured mesh backrest follows the natural curve of the spine to support mid- and lower-back alignment. Adjustable lumbar support moves vertically to accommodate different body types, while the headrest adjusts to support the neck and shoulders during work and rest.

A smooth reclining mechanism allows you to shift between upright tasking and relaxed tilt positions, helping reduce static sitting throughout the day. Breathable mesh, height-adjustable armrests, and a well-padded seat cushion round out the comfort-focused design.
