Not a conventional desk chair but very comfortable for me. Excellent support for my back and neck which was badly injured when I was in the Army. Wish I had bought this a long time ago.
i am 5'6" have 2 plates in my cervical spine and wear progressive lenses. this chair lets you adjust the seat back closer to or further back from the from edge of the seat.the height adjustment is pretty good. it could be about an inch higher for my prescription. at my height the headrest is perfect.
As a big guy over 6 foot it's hard to find an office chair that fits me let alone one that isnt cheap leather or vinyl. This is a very comfortable chair with support all the way up and it supports a pretty heavy person. Very easy to assemble. Lost a star because the head/neck rest is only useable when you are reclined. If it would tilt further forward to support your head for the 3pm slump it would be 5 stars.
