Features
- LUMBAR SUPPORT THAT MOVES WITH YOU Your posture changes constantly throughout the dayyour lumbar support should too. The B300 PRO ergonomic office chair features a spring-assisted 4-way lumbar system that adjusts in height, glides forward independently, and flexes with every movement to stay aligned with your lower back. Whether you're diving into focused work, switching between meetings, or reclining to recharge, it delivers continuous support that helps relieve pressure and keeps you comfortably centered from morning to night.
- A BACKREST BUILT AROUND YOU Great ergonomics begin with a chair that adapts to younot the other way around. The independently height-adjustable backrest lets users of different heights fine-tune where lumbar support meets the spine, creating a more natural sitting posture and full-back contact. From your home office to a shared workspace, every adjustment brings balanced support that feels personalized, stable, and effortless throughout the day.
- SIT DEEPER. FEEL LIGHTER. Comfort starts where pressure ends. The adjustable seat depth helps evenly distribute body weight while providing better thigh support for different leg lengths, reducing fatigue during extended sitting. Whether you're powering through deadlines, studying for hours, enjoying immersive gaming, or simply settling in with a good book, the breathable mesh seat keeps you cool, supported, and comfortably focused without constant repositioning.
- RECLINE WITHOUT THINKING Your chair should respond as naturally as your body moves. The smart weight-sensing recline automatically matches your body weight, delivering smooth, balanced resistance without manual tension adjustments. Shift from focused tasks to creative thinking, lean back between meetings, or pause for a quick breakthe chair follows your movement seamlessly, so every position feels stable, supported, and completely intuitive.
- SUPPORT FROM HEAD TO ARM Comfort is built from every point of contact. The oversized 3D headrest adjusts to support your neck during long video calls, reading, or quiet moments of relaxation, while the 6D armrests rotate, slide, lift, and flip up to match everything from typing and creative work to gaming or sitting cross-legged. Together, they help keep your neck, shoulders, and arms naturally alignedso comfort stays with you no matter how you work or unwind.
- ENGINEERED TO LAST SUPPORTED WITH CONFIDENCE Built with premium-quality materials and rigorously tested to meet BIFMA, SGS, and TV standards, the B300 PRO is designed for years of dependable ergonomic comfort.
