This chair was so close to being perfect for me but not quite. I'm 5'4". I see now why so many people commented that the chair was too small for them. I have the lumbar support and the head rest at the highest levels and it's perfect for my short stature. The chair is rated up to 250 pounds for 5-10 hours...not so much. A 250-pound person will be squeezed into this chair. I'm 220 pounds and my hips barely fit into the 17.5-inch seat. Kinda feels like I'm on an plane that's how cozy the seat is. Wouldn't be an issue except the nylon mesh is stretched over a frame with no other cushioning around the sides (there is very nice cushioning under the knees). 220 pounds sitting on this chair for 3 straight 8-hour days and the nylon mesh has stretched ever so slightly. Now the outside of my hips are actually sitting on the hard plastic frame. Extremly uncomfortable. I think a short skinny person would enjoy this chair. Big tall and or even worse...both big & tall will most definitely be uncomfortable in this chair. I can't comment on assembly as I had the store do it for me. The cheap tool included with the chair would have taken forever to assemble the chair with. I returned the chair but couldn't get a refund on the assembly fee.
I love the chair and the adjustments are almost as good as my work office chair. I am only 5 foot 3 so the head/neck rest hits me a little high but otherwise it's way better than I hoped for for the price.
I bought this chair because it said more than 3 hours of use. It's a very stiff chair. Not real comfortable for sitting 7 or 8 hours. Maybe it will get better after a few more weeks of use.
I sit for at least 8-10 hrs a day and I have found this chair to support my back and leg circulation. I would recommend this chair to all of my co-workers
I hope the mesh lasts because this is a great very comfortable chair. The parts are made well and the structure parts are made of sturdy metal including the center post.
I have had all of the more expensive chairs and this one is good value for style comfort and functionality. What is great is the lower part that sticks out for the back
