This was a gift, and the recipient indicates he likes it! I have one, in another color, and I am very pleased with my chair. It is very comfortable. You can sit back with a head rest. I replaced a 20+ year old chair with this one. It was time!
I have a bad back. I originally sat in the chair in the store and it felt pretty comfortable. After using an extended period the lumbar support is HORRIBLE! Bites into my lower back. It's not support. It's TORTURE!
Bought this chair for office use in my home. Tried it out in the store and thought it would fit my needs. I WFH two days a week and generally am sitting all day. The seat is very sturdy and conforms to my back and when you recline back a bit it is just as comfortable. I like that you can adjust the arm rests up and down and the head rest is good as well. Someone I know has this chair and said that the only issue is when it is cold (winter months) that one may feel the cold quite a bit (since the chair is of course mesh). I will have to just wait and see as it gets colder and maybe add a blanket to the seat which to me does not seem like a deal breaker on the chair. Very happy with the purchase thus far.
None of the locks actually hold anything in place. You can hear it click when you set the recline position, but it immediately unlocks as soon as you sit in the chair. Same for the lumbar support, you can pull it up, but it drops back down immediately. Are rests have buttons to move the arms in and out, but again, as soon as you rest your arm on it, it slides out regardless of the lock.
It works as a chair, but it only pretends to be anything comfortable with customization.
The chair is not the right size for me. I am not a very tall person (5'10") but the neck section sits too low and hits me in the shoulders. I will not be keeping this chair long.
