Really nice chair once you get it together. A little bit of a pain putting the back on as the instructions need to be changed a little. Put the base on last not first.
All in all we like the chair but there was a problem trying to put the arm together. Holes were not properly drilled or something. We finally got it all to line up and work but not without significant time and frustration.
This a very comfortable chair to sit in for hours. My husband has a neck injury plus spinal injury and he loves this chair. Hard to get him out off it so I can use the computer.
