I've only had it a couple of days but this chair is comfortable. It has seat arm and back adjustments that many chairs do not. Great price great chair.
Being able to adjust the lumbar support the angle of tilt of the back rest and the ability to lock the tilt allows you to achieve maximum comfort. I am in the chair 8+ hours each day and after 5 days of use I have no complaints.
I ordered this chair because it seemed like a good price (89.99) for a mesh task chair. The first I had for a couple months and the staples around the frame that held the mesh started to pull out. A couple weeks after this began around half were out. Staples sent a replacement. I have now had the replacement for approximately 2 months. The same problem is happening. I am an average size male (5'10" 185lbs). I do not recommend this chair.
Got this chair for my college student son put it together easily but once together the staples that hold the back mesh to the frame immediately started coming out. Then we couldn't get the chair disassembled completely to get it back into the box for a return. I will be exchanging it for another of the same chair but am disappointed that the workmanship seems to be so lacking and the design misses some important things like how to get the base back off the wheel assembly in case the chair needs to be re-packaged. I hope the next chair is built better.
