4 reasons to love Sihoo M18 Ergonomic Chair
Made for every moment
From focused work to relaxed reading, the M18 keeps you comfortable in any setting.
Adjustable comfort
Easily adapts to different body shapes, giving you personalized comfort in any position.
Soft, spacious seat
A wide W-shaped cushion offers soft, balanced comfort that lasts all day.
Quiet and floor-friendly
Smooth, silent casters glide easily without scratching or damaging your floors.
For every part of you
2D Adjustable Headrest
The soft, single-joint headrest smoothly adjusts through 8 height levels and tilts 45° up or down, perfectly aligning with your neck and head in any sitting posture.
2D Adjustable Lumbar Support
Easily rotate the knob directly behind you to move the lumbar support forward or backward, or lift it up and down through 7 height settings to find your ideal lower back position.
1D Adjustable Armrest
Press and hold the side latch to raise or lower the armrests by up to 2.8 inches (7cm), with a 1.6-inch-thick and 4-inch-wide pad that keeps your arms relaxed.
3-Stage Adjustable Recline
Switch between three lockable recline angles — 110°, 118°, and 126°, simply by pulling the side lever about 0.4 inches (1 cm) outward to activate your preferred lean.
