Very comfortable chair. I would have given a 5 star if the head rest were adjustable. I just removed it and chair is much more comfy for my height. It was very easy to assemble as well.
Reviewed a number of home office chairs before trying this one in store and was impressed with the quality and comfort. Found it deeply discounted online so I decided to purchase. I have used for a few weeks and am extremely happy with the chair.
I've had this desk chair for two weeks so far and am very satisfied (compared to previously using a kitchen chair) while working from home during covid. I test drove the desk chairs with a mesh seat bottom and back at Staples and this one felt the best. The only concern (not enough to bump down to 4 stars) is that when I sit fully back into the chair the head/neck rest (rotated all the way up) hits the top of my shoulders/base of my neck. I'm 5'-10". So the only improvement i would suggest would be to add more vertical adjustment in the head/neck rest.
I am 6' and I could not use the headrest. Sitting in this chair as intended (not slouching) the headrest would be at my shoulders. The chair was comfortable even for 10 hour shifts. Only other notes are that the mounting points don't line up perfectly and there is some wobble to the arm rests
