SIHOO B100 Ergonomic Chair – 2D Wide Headrest, Flip-up Armrests, Breathable Mesh Backrest, 150kg Max Load, White

Support starts at the base of your spine.

Most chairs focus only on the lower back. The B100 starts lower – and uses targeted sacral support to stabilize your pelvis, promote a healthy S-shaped posture, and prevent fatigue during long hours at your desk.

Designed to work, rest, and recharge.

Lock the backrest in three recline positions – suited to every moment: upright when you need maximum focus; slightly reclined to reduce pressure; or fully reclined when it's time to recharge your batteries.

A wider headrest for better neck comfort

The extra-large 2D headrest provides particularly stable support for your head and neck – thanks to its positional adjustment that ensures optimal support whether you're sitting upright or leaning back.

Flip-up armrests that adapt to your space

The 2D armrests support your arms as you work, study, or play, relieving shoulder tension while offering a flexible and easy-to-manage configuration.

Adapts better to tight spaces.

Flip up the armrests and tuck the chair neatly under your desk when you're done. A simple feature that makes a big difference in apartments, shared spaces, and cramped work environments.

Comfort where your body needs it most.

From the head and neck to the lower back, hips, thighs, and arms – the B100 is designed to precisely support those key pressure points that are most stressed during prolonged sitting.

Pressure relief that gets better over time

The ergonomic seat is designed to distribute pressure more evenly across the hips and thighs; this helps reduce localized pressure points and ease tension behind the knees during extended sessions.

Breathable comfort, reliable support

Woven from high-quality fibers, the premium mesh fabric offers resilient, breathable support. It stays pleasantly cool against the skin, resists daily wear and tear, and is easy to clean.
