B100 Se is an office chair designed to keep you comfortable and productive at work. Compared to the M18, the B100 Se features an additional backrest in terms of ergonomics. While traditional office chairs have a single backrest, this ergonomic chair adopts a dual-back design. We've made the lumbar support detachable, achieving the ultimate level of support and fit to the natural curve of the human body in this field. This executive chair is not only suitable for use as an office chair but can also serve as a gaming chair. For example, when I want to lie back and play games, this ergonomic chair offers three reclining angles: 113°, 123°, and 135°. These thoughtful positions are ready for your "battle mode," allowing you to fully immerse yourself in the gaming experience. The wide headrest provides excellent support whether you turn your head left or right. This ergonomic chair has also passed BIFMA and SGS testing, adding an extra layer of safety assurance. This office chair will bring you a healthy lifestyle. Just relax, just sit, just do it.

Way More Comfortable Than I Expected! This chair was super easy to put together, which was a great start, but I was honestly surprised by just how comfortable it is! The ergonomic lower back support is amazing; definitely better than most office chairs I’ve tried. I especially like how the lumbar support encourages you to sit upright instead of slowly ending up hunched over your desk by the end of the day. The high back and headrest add even more support and make it comfortable for sitting for longer periods of time. If you spend a lot of time at a desk and want an everyday office chair that is comfortable while also helping with better sitting posture, this is a great option. Easy assembly, excellent back support, and much more comfortable than I expected. Definitely a great office chair for the price!. Laurin. Leland, NC. Wed Sep 23 2026
