• 【Ergonomic Backrest Design】Curved backrest can perfectly line up with human body curve and support your spine’s natural curve. The lumbar support system resembles a pair of hands, pushing up and holding your low back. 【Adjustable Seat Height】The seat height of this computer mesh chair can be simply adjusted from 35cm/13.8’’ to 45cm/17.7’’ by a little push-up/press down at the lever under the seat according to your needs. 【Larger Seat for Optimal Comfort】In this model, we upgraded the seat size, measuring 52.5cm/20.7’’ (width) by 51cm/20’’ (depth), and 7cm/2.8’’ thick, to provide you with a softer and larger sitting area. 【Star Base & 360 Degrees Wheels】Twisting and turning about is integral within the office. So we adopt a stable star base and furnish it with 5pcs 360-degree swivel wheels, ensuring fluent and quick movement and keeping up your quick pace of work. 【Easy Assembly Required】We provide all the necessary hardware and tools, and an illustrated installation manual to help you set up this chair.
