I built this myself right out of the box with no trouble. I really like all the adjustable features and have been very comfortable sitting on this at my desk.
I have a bad back and I got this chair for my home. I have the same one at work. It’s one of the few chairs I can sit in for prolonged periods without my back being destroyed.
Supportive mesh back and mesh seat chair with all I need for home office use: adjustable seat height adjustable back tilt and lock adjustable arm height adjustable tension. Easy to assemble with good instruction pamphlet and everything needed packaged in the box took me less than 15 minutes to get it all together. Seems solid and sturdy over the first week of use great value for the price.
