SIHOO’s M57 Ergonomic Office Chair combines durability and comfort, certified by BIFMA and SGS withstanding up to 150kg. Its breathable mesh back and seat ensure ventilation for extended sitting periods, maintaining comfort without overheating. The 3D adjustable armrests offer precise customization—forward, backward, height, and 36° rotation—to support your ideal posture. Designed with ergonomic principles endorsed by the Ergonomics Application Association, the S-shaped backrest and adjustable lumbar support alleviate spinal pressure, while the waterfall seat promotes relaxed thigh positioning. Ideal for hard floors or mats, this chair balances advanced functionality with refined design for long-lasting office comfort.

Product Features
  • Certified Quality & Durability: BIFMA and SGS certified; passed 1000 kg static pressure test and multiple safety tests (cushion impact, armrest fatigue, base pressure).
  • Breathable Mesh Design: Mesh back and seat promote air circulation, keeping you cool and comfortable during long sitting sessions.
  • Long-Lasting Comfort: Abrasion-resistant mesh and 8-hour comfort support make it ideal for all-day use.
  • Easy to Clean: Mesh material is easy to maintain—machine washable with warm water and a gentle cycle.
  • 3D Adjustable Armrests: Armrests move up/down, forward/backward, and rotate 36° for customized arm support.
  • Ergonomic Support: S-shaped backrest mimics the spine for improved posture; adjustable lumbar support and waterfall seat edge reduce pressure on spine and thighs.
  • Smooth Mobility: Includes castors for easy movement (recommended for use on hard floors or with a floor mat).
  • Flexible Functionality: Adjustable seat height and backrest, 360° swivel, and smooth gas lift.
  • Sturdy Construction: Made with high-quality materials including nylon, PP, iron, and aluminium.
  • Modern Design: Sleek, contemporary style suited for home or office use.
  • Simple Assembly: Tool-free 8-step assembly process with clear instructions.

Care Instructions

To keep your office chair in top condition, regularly wipe down the frame and base with a damp cloth to remove dust and debris. For fabric or mesh upholstery, vacuum weekly and spot clean with a mild detergent as needed. If your chair is leather or faux leather, use a suitable leather cleaner and conditioner to prevent cracking. Periodically check and tighten screws or bolts, and lubricate wheels and moving parts to maintain smooth function. Avoid placing the chair in direct sunlight for extended periods to prevent fading or material damage.
