Ergonomic backrest design: Curved backrest can perfectly line up with human body line and support your spine’s natural curve. The lumbar support system resembles a pair of hands, pushing up and holding your low back. Star base & 360 degrees wheels: Twisting and turning about is integral within the office. So we adopt a stable star base and equip it with 5pcs 360-degree swivel wheels, ensuring fluent and quick movement and keeping up your quick pace of work. Reclining office chair: By simply pushing the lever or pulling it out, this mesh office chair can be tilted and leaned backward or locked in place for your various sitting positions. A tilt tension control knob under the seat is provided to adjust the recline angle. 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. Reliable home/office accessory: Sold in a pack of 2 office chairs. These basic ergonomic mesh chairs are perfect for your reading nook or home office. A good office chair can be beneficial to a productive workday. Imagine sitting on a hard leather seated, lack-of-maneuverability, unadjustable, weak back-and-lumbar-supportive office chair, I suppose you won’t have a very comfortable working experience, nor a good efficiency, not to mention a pleasant mood. 360° swivel ergonomic chair is your ideal choice for your office and home.
