Had to return, Chair 2 inches too tall for me 6'0'' tall to seat at office desk. If my desk was adjustable I may have kept it. The back leans back, very comfy if you are leaning back in it, the recline wouldn't lock up straight. Seat Cushion very comfy, Great structure but I think it's flawed.
Although comfortable, Changing the chair height is very difficult for a senior over 80 like me and I had to get someone else to do it. Although it says it will roll on a carpet with no special mat, at 164 lbs. I have found it very difficult. OTOH if it was on a hard surface it would be too easy to stand up washout it getting away from me.
the chair is very comfortable and was relatively easy to put together. i like the headrest but the pivot point to angle the headrest without moving the arm doesn’t have a locking mechanic so the headrest always ends up falling back to the lowest point.
