I really wanted to like this chair,
it looks good, it is a nice size, and it starts out pretty comfortable. The vinyl seems pretty durable and I've not had the troubles others have noted with seams tearing or starting out faulty, mine have been near perfect. Assembly is easy, just 12 screws and you simply put them all in finger tight, then toque them down a bit at a time over about 3 passes to get them evenly tight while letting everything balance out as it goes. Much like changing a car tire. If you install one screw and tighten with all your might then move on to the next you'll have trouble with anything you try to assemble, including this chair.
Assembly is rarely a problem for me, but the issue here is the padding. I weigh less than the weight limit but I'm tall and thin and my muscular bicyclist's butt is apparently too much for this chair's cushions. At 8 months, I gave up on blankets and pillows and Amazon politely replaced my first chair with zero fuss. Two months later I got a job telecommuting and the 2nd chair has gone totally flat in only another month. I really wanted to like this chair, but the padding just doesn't last. Update: I've been using an additional pad in the seat and though I'm not fond of the look, the price is right since I already paid for the chair. A couple days ago I leaned back and hear a "pop". The back is all floppy and so I take it apart looking for the problem. I tracked the problem to a metal bracket inside the upholstery. I had to cut the vinyl to reach the problem but found the bracket is a large well engineered solid steel plate with plenty of surface area to handle the stresses and the wood is top quality plywood with no voids. Amazon did an awesome job having this chair re-engineered and specified good materials, but their assemblers didn't bother to tighten the screws. No amount of engineering can fix lousy assembly work. Amazon is clearly trying here but they're being thwarted by their supply chain left and right. To be fair, the two chairs they have sent me collectively did last enough for the price I paid so I won't be asking for another replacement.

Solid quality and comfortable
Color: Light Grey, Color: Light Grey
Wonderful quality chair, solid and sturdy, it was easy to put together, the directions were very clear and all the pieces fit together perfectly without issue. It is made of breathable material and I love that the arms flip up easily. You can raise it up or down and it has an adjustable headrest. It also has adjustable lumber support. It rolls easily and the color is the only reason I might return, I think I want a different one instead. The chair is comfortable for a petite person but equally comfortable for a tall person. We have both in our family and it is great for both. The armrests are comfortable and there is really nothing negative to say about this chair at all. Considering the quality, it is a great value for the money.

Comfortable and easy to set up
Color: Black, Color: Black
I’m happy with this chair. It was not hard to assemble, and it feels stable after putting everything together. The mesh back is comfortable and breathable, so it doesn’t feel too hot when sitting for a while. The seat cushion is also thicker than I expected and feels soft enough for daily use. I like the adjustable headrest and the back support, especially for working at a desk. The chair looks simple and clean, and the wheels move smoothly. Good value for a home office chair.
