It took me about 90 minutes to assemble the chair and I am pretty savvy on instructions.and using tools. The chair is not as comfortable as I thought it would be
I bought this chair for work because I sit for 8-10hrs a day and have back issues because of it. I've only had it for a week but so far it has been comfortable all day. (I have a footstool too.) Overall I am happy with this chair because I'm not constantly shifting around trying to get comfortable. I was concerned about the armrests not being adjustable but that has not been a problem. I am 5'-6" tall about 145 lbs female and I find that the depth width lumbar and back height of the chair are the proper size. The back is up straight enough where I don't feel like I have to lean forward (which is huge!) but can tilt if needed. It rolls and adjusts easily. The material isn't the finest quality but not bad either. Hopefully it will hold up for a few years at least.
