Overall really great chair. Comfortable great value when it's on sale and seems nice and sturdy. Only two complaints: The tilt tension doesn't feel like it really does much (when not locked the seat is always a little too easy to lean back in) and I'm of very average height (probably even on the lower end of average?) and the head rest is too low. To really take advantage of it I have to scoot my butt forward to the point where the lumbar support isn't doing anything for me. I shuffle around a lot in my seat over the course of the day so it's not a dealbreaker for me but this would be 5 stars all day if the back was adjustable or just a little taller.
I'm 6 feet tall. When I sit straight he head / neck support protrudes into the back of my upper back and shoulders and isn't adjustable. The chair otherwise seems OK. If you're 5 foot 7 this may work well for you.
I first purchased this chair several years ago for the workplace and liked it so much that I bought one for home. I recently changed departments and just got another one. It's comfortable for someone who is barely 5'2". I don't use the detachable headrest but I imagine taller people would appreciate that feature.
Been using it for about 3 weeks now and I love it. Perfect height for me (i'm 5'2). Very happy with all the adjustable features- I can adjust the arms high enough so that I can sit cross legged. I especially recommend this chair if you like to rock and or swivel back and forth. My only dislike so far is that I wish the armrests were cushier.
The Chair was easy to assemble with the directions and tools provided. Two items to be aware of.. 1. This chair is best suited for those under 6'0" probably only 5'10". I'm 6'1" and when assembled the headrest was hitting my shoulder blades even at its highest setting I removed it altogether. 2. It is indicated in the specifications by its absence. Be aware that the seat does not slide forward to support your legs/thighs. Other than that it does seem well built and does have good lumbar support.
