Support Starts at the Base of Your Spine
Most chairs focus only on the lower back. The B100 goes lower—using targeted sacral support to help stabilize your pelvis, encourage a healthier S-shaped posture, and reduce fatigue during long hours at your desk.
Arm Support in 4D and 360°
Lean Back Further. Relax Better.
3 Recline Angles to Suit Your Day
Recline up to 135° and extend the footrest for more complete leg support—ideal for quick resets between tasks or a more comfortable midday break.
Designed for Work, Pause, and Reset
Lock the backrest into three recline positions to match the moment—upright when you need focus, slightly reclined when you want less pressure, or leaned back when it’s time to recharge.
A Wider Headrest for Better Neck Comfort
The extra-wide 2D headrest gives your head and neck a more secure place to rest, with adjustable positioning that helps you stay supported whether you're sitting upright or leaning back.
