A solid chair for the budget conscious sitter.
While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best. It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete! I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up. Okay! I can live with this. It has been almost two full months of using this chair and I have no problems. Pros: easy to assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like that Overall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough. I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.

Good medium priced office chair with a few problems
I bought this during Prime Days and got a good deal. I am not an expert on chairs, but I've bought about six office chairs in the last decade. These are good chairs. I would buy again. Pros: - reasonable price - comfortable for both my self and my wife - seat is large, good thigh support, and soft - adjustable arm rests, lumbar supports, head rest, and tilt stiffness - nice! - somewhat easy to assemble - the screws and parts are in a blister pack with a couple extra parts Cons: - rollers do not roll as easy as some chairs Assembly notes: - as a retired tech writer, I'll give the Assembly Guide a 70% - it's all illustrations and the illustrations are not large enough - the parts labels don't always match the assembly instructions - don't forget the washers - it's hard to see in the illustrations, but most bolts use them - the casters are difficult to install into the bottom frame - use a light coat of three-in-one oil on the caster stems and they will go in easily - it is difficult to attach the chair back to the seat - put both parts on the ground and concentrate on getting one bolt in, the others will be easy to get in

Best Chair EVER! Read how it was determined…
I started working from home in June. I had an old 20+ year desk chair that had seen better days, and it was so uncomfortable, not sure why I was still using it. My knees and back hurt after sitting on it for 8+ hours a day. Mind you, I had come from a field job where I sat in my car for 8 hours a day, and that was even more comfortable than my old desk chair. So, figured it was time to purchase a new desk chair. I didn’t want to spend a fortune and I looked at the local office stores and they were either too expensive or just not comfortable when I sat on them. So I decided to check out Amazon and I am so glad that I did!! I actually ordered 3 different chairs as I wasn’t sure what size or type would work for me. When they arrived, it was like Goldie Locks and the 3 bears story. I set each chair bottom and backs on my couch (didn’t want to put them together, to not be able to get apart to return), and lined up side by side, it was looking at small, medium and large chairs in a row. One was too small, one was too hard and back too short, and one was just right, which was this chair!! It was the tallest of the three and seemed the best quality as well. I was concerned that the bottom cushion was going to be too hard, but when put together and used daily it actually is very comfortable. It gives support and my knees don’t hurt at the end of 8 hours! The back gives just the right support and is nice that it can lean back if you need it too. I haven’t really had a need to use the headrest, but know it is there if I need it, which neither of the other chairs came with. After using every day for the past two months, there have been no problems or complaints when using this chair. It moves around fine and the arm rests are comfortable with the slightly indented center areas for your arms to rest. The one and only thing is it has started to squeak from time to time, so I hope that it doesn’t get worse. I haven’t tried to source where it is coming from or tried to oil it, so for now it is a very minor nuisance. Overall for the price and the quality and comfort I would recommend this chair and hope that it lasts for years to come!!!

High hopes!!
I’ve had the chair a few days now and so far I’m enjoying it!! It feels sturdy when reclining all the way and is comfortable to sit in for a few hours. Will update if anything changes but I have a good feeling about this one

I am giving 4 star because the height is not high enough for me.

One of the nuts was completely loose in the seat. I will have to fix it myself.

Great value for money. Assembly is relatively easy but can be a bit confusing. The product is sturdy and provides ample support. Cushion may feel hard initially but settles well. Way better than many other brands that I have tried and gives comfort similar to Herman Miller chairs - unsure about durability. Only issue I have is with the headrest. It was too tight to go into the slots and I had to remove the holder to fit it. It is still a bit too tight to adjust easily.

I am a person over 200 pounds. I sit for long periods for work. Since I got this chair I haven't had any back pain. I'd say my only complaint is the seat could be a little cushier but compared to other chairs I've had, this one is excellent. It was easily adjustable for lumbar support. Another nice thing is the arm rests don't seem to loosen, I end to lean on them a lot. Haven't tightened a screw in months of usage so far. Rolls well, my shoulders don't hurt or touch the outter frame of chair. Headrest is not much use to me but doesn't get in way and is adjustable.

Facile à monter - confortable et soutien bien le dos et le tête. Rien à redire
