The B300 PRO ergonomic office chair is built for real life—work, study, gaming, and everything in between. Its upgraded self-adaptive lumbar support moves with your back, while the height-adjustable backrest fits your body perfectly. The adjustable seat depth and breathable mesh keep you cool and supported for hours. When it's time to relax, the weight-sensing recline and retractable footrest let you stretch out and unwind effortlessly. The oversized 3D headrest and 6D armrests keep your neck, shoulders, and arms aligned. This ergonomic mesh chair is also a great ergonomic desk chair, ergonomic gaming chair, and ergonomic study chair—all in one. Tested to BIFMA, SGS, and TÜV standards, it comes with a 3-year warranty, 30-day returns, and 24-hour support.
Your body never stays in one position, and this ergonomic office chair keeps up. The 4-way lumbar system moves up, down, forward, and bends with your back. It supports you during deep work, meetings, or relaxation—helping reduce pressure and keep your spine comfortable all day.
This mesh office chair adapts to you, not the other way. The height-adjustable backrest lets you find the perfect fit for your spine. It encourages natural posture and keeps your whole back in contact with the chair—so you feel balanced and supported, whether you're tall or small.
Long hours need real comfort. The adjustable seat depth supports your thighs perfectly, while the retractable footrest lets you kick your legs up and relieve pressure. Whether you're working, studying, gaming, or taking a break, the breathable mesh keeps you cool from start to finish.
Switching from work to rest is easy. The smart weight-sensing recline adjusts to your body automatically—no buttons, no fuss. Pair it with the footrest to stretch out fully, reduce leg tiredness, and enjoy a light, floating recline during movies, breaks, or quiet moments.
Comfort isn't just for your back—it's for your whole body. The oversized 3D headrest supports your neck, while the 6D armrests adjust to any position for your arms and shoulders. Add the retractable footrest, and your legs get support too. This ergonomic chair gives you complete, balanced comfort from head to toe.
