The Sihoo M18 is a high-back mesh office chair built around an ergonomic S-curve backrest, a thick W-shaped foam seat and a bidirectional adjustable lumbar support. It adds a height- and angle-adjustable headrest and soft armrests that move up and down, so it covers the neck, back and arms rather than just the seat. It suits people who sit for long stretches at a desk and want adjustable lumbar and neck support without stepping up to a full ergonomic flagship. Against basic mesh chairs it offers more adjustment points; against premium ergonomic chairs it has fewer tuning options and a simpler tilt mechanism.

Owners generally rate the M18 well for its lumbar support, breathable mesh and sturdy build at its level. Common complaints center on firm seat padding and armrests that lack side-to-side adjustment.
The Sihoo M18 is a high-back ergonomic office chair with a mesh backrest. The mesh is breathable, high-strength and stain-resistant, so air can circulate during long periods of sitting. The backrest follows an S-curve shape to fit the curve of the back and support the cervical and lumbar spine.
The seat cushion is 3.15 inches thick, made of high-elasticity foam that resists deformation and dirt. Its W-shaped design helps relieve pressure on the thighs and lower back. The lumbar support adjusts in two directions, and the headrest adjusts to support the neck.
The soft armrests can be fine-tuned to suit your body, posture and desk height. The backrest locks and has a tilt adjustment. The chair has passed US BIFMA and SGS testing. It comes with instructions, labeled parts, extra screws and rubber gloves, and can be assembled in about half an hour.
