Dynamic Lumbar Support That Moves With You
Long hours at your desk shouldn’t mean an aching lower back. The SIHOO B100 features dynamic lumbar support that adapts to your posture—whether you’re leaning in to focus, sitting upright, or shifting throughout the day. Your back stays supported, never stiff.

With seat height adjustable from 18.3" to 21.9", the B100 adapts to your body and workspace. The adjustable headrest supports your neck while you type, call, or lean back—so sitting feels natural, not forced.
Recline, Reset, Refresh
Three lockable angles—110°, 125°, and 135°—let you move seamlessly from focused work to full relaxation. Recline to release tension or recharge. Comfort follows you through every shift and break.
Breathable Mesh That Works as Hard as You Do
The full-mesh backrest promotes airflow, keeping you cool through busy afternoons and late nights. Supportive, breathable, and built to help you stay comfortable all day.
Sit Longer, Feel Better
A widened seat cushion distributes weight evenly across your hips and thighs. Whether working, studying, or gaming, this chair delivers balanced comfort that lasts.
