Our Verdict
The SIHOO M18 is the budget ergonomic office chair most people end up comparing everything else against, and its Amazon rating comes from more than 17,000 buyers. It has a mesh backrest that stays cooler than the faux leather on most gaming chairs, a built-in lumbar support instead of a strap-on pillow, and an adjustable headrest, seat height and back support. SIHOO says it passed the BIFMA office furniture test, supports up to 150kg (330 lbs) and suits people from 5'6" to 6'2" tall. Assembly takes eight steps, and SIHOO covers parts for three years. It has no deep recline and no footrest, so it is a desk chair first, not a lounging chair. The seat uses foam rather than mesh, and taller users above 6'2" should look at a bigger chair. Choose it if you sit at a desk for four or more hours a day and have under $150 to spend. If you mainly game reclined or want a racing look, a gaming chair suits you better.
