After a semi-extensive search for a good chair at a reasonable price I found this chair. It's pretty well-made and the seat is adjustable to accommodate various desk heights and the arms are also adjustable. Seat and back are made of mesh and they are fairly supportive. Those with back problems may need extra support.
I love this chair it is very comfortable to sit in for long periods of time since it has breathable material it glides easily and gives you a lot of support.
As mentioned by other customers the chair is uncomfortably high at the lowest setting. I am 6 feet and after a couple of weeks with this chair my lower back hurts and my hips are strained from stretching my legs. I would recommend finding something more adjustable or replacing the hydraulic lift with a shorter one (like from an old chair if you can get it separated).
