SIHOO B100 Ergonomic Office Chair with Adaptive Lumbar Support
The SIHOO B100 ergonomic office chair adapts to your movements with dynamic lumbar support that follows your spine's curve. A widened seat cushion distributes weight evenly, while the breathable mesh back keeps you cool. Three lockable recline angles (110°, 125°, 135°) and a wide adjustable headrest allow you to switch between focused work and breaks. Flip-up armrests save space, and the reinforced metal base supports up to 300 lbs. Quiet casters and smooth tilt control make it ideal for home offices. Built to SGS and BIFMA standards, backed by a 36-month warranty and 30-day returns.
