Sihoo M76-1 Ergonomic Mesh Office Chair - White Frame, Lumbar Pillow & Flip-Up Armrests

Designed for the modern home office or study, the Sihoo M76-1 pairs practical ergonomic adjustments with a two-tone black-and-white finish that sits comfortably alongside contemporary interior schemes. SPACE AND STYLE The chair's overall footprint - 55 cm (21.7 in) deep and 66 cm (26 in) at the base - keeps it proportionate in home office rooms without dominating the space. The white nylon frame and base with contrasting black mesh back complement white desks, light timber finishes, and minimalist shelving equally well. ERGONOMIC FEATURES FOR DAILY USE The C-arc/S-shaped back profile is contoured to follow the spine's natural line, making it a practical choice for reading, video calls, writing, or desk work. The independently adjustable lumbar pillow moves up and down along the 59 cm (23.2 in) wide back frame, held in position by a flexible elastic mechanism that gently gives when you shift in your seat. ADJUSTMENT AT A GLANCE Seat height is set pneumatically anywhere between 41 cm and 49.5 cm (16.1-19.5 in) - 8 cm of range to suit varying desk heights. Recline travels between 90° and 120°, with tension adjusted by a knob under the seat and a lock at 18° tilt. Flip-up armrests fold flat at 90° to tuck the chair neatly under desks or clear space in multi-purpose rooms. SEAT COMFORT The 47 cm × 43 cm (18.5 × 16.9 in) high-density foam seat includes double-sided ventilation holes that allow air to pass through the cushion from both above and below, keeping the seat surface cooler during extended use. FLOOR CARE Dual-wheel PU-edged castors protect hard flooring and roll without sound on tiles, wood, and laminate. The five-point base (66 cm / 26 in diameter) provides stable full-swivel movement. CARE: Wipe the mesh back with a lightly dampened cloth; clean the seat with a dry or slightly damp cloth. Avoid harsh solvents on any surface. Covered by a 3-year manufacturer's warranty.
