Comfortable seems solid built tilting is very good. Head rest I can take or leave. Instructions to build the chair were the best I have ever seen. The only thing one of two plastic screw holes on the headrest was stripped out but the screw is snug and the headrest is seated in such a way that it really doesn’t effect anything.
I have an old executive desk with drawers on each side and a pencil drawer directly over the foot well. The arm rests on many desk chairs are too long and too low so they run into the desk before I can scoot far enough forward and don't provide support for using a keyboard on the desktop. By contrast this chair has shorter arm rests plus they're adjustable in height so I can finally scoot forward enough and get arm support to comfortably use the keyboard on the desktop. This chair also has great back support and a comfortable seat. I think it's more comfortable than my Herman Miller Aeron chair at work which costs about four times as much. This chair obviously isn't the same quality as an Aeron but I'm not using it in a commercial environment either. I gave it four stars because it doesn't fit in with home decor but I haven't been able to find a supportive chair that does. Hugely better lumbar support than the La-Z-Boy Bradley which I had to return for that reason.
I purchased a new chair because I kept experiencing back issues with my old chair. This chair is perfect! The adjustable arm rests are great for proper desk posture as well as the adjustable lumbar and head support!
This is the best desk chair I have ever purchased. Easy to assemble. Great looking and very functional! I cannot recommend this enough. I am very pleased with the purchase. Fast delivery. High quality great store!
