The chair is very comfortable and fairly easy to put together. I would have given it a 5 if I hadn’t gotten to putting on the headrest and see that they gave the wrong size screws. Now I don’t have the headrest which was one of the main reasons I bought this chair.
After owning this chair for just over a year it is hard to sit in comfortably anymore. The back does not lock upright in the locked position I sit at 120 degrees instead of 90. I am 6'5 220 lbs
