Buying guide
An ergonomic chair should support your lower back, neck and arms through a full working day. Adjustability is what you are paying for.
Your lower back needs support at the right height. The SIHOO M57's lumbar moves up, down, in and out.
A headrest helps when you lean back. The SIHOO B100 reclines to 135° and locks in 3 positions.
Mesh lets air through, which keeps you cooler than foam on hot days. The M57 is full mesh; the M18 pairs a cushion seat with a mesh back.
Adjustable or flip-up armrests let the chair slide under your desk and keep your shoulders relaxed.
Our top pick is the SIHOO B100. It reclines to 135°, has a wide 2D headrest and flip-up armrests, and is rated to 330 lb.
The SIHOO M57. Its full mesh seat and back keep air moving, and it has 3D armrests and adjustable lumbar support.
The SIHOO M18. It has a cushioned seat, a mesh back, an adjustable headrest and is rated to 330 lb.
Mesh is cooler and keeps its shape. A cushioned seat feels softer at first. Many people prefer a mesh back with a cushioned seat, like the M18.
