I replaced my Herman Miller Aeron chair with this chair and this is exactly the lumbar support I have needed for years.

Worth

Some reviews complain about the assembly, and I imagine this is due to the chair's many parts and many screws. For example, the base of the chair has six parts, not including the wheels: a center piece, and five legs, each leg attached to the center piece with two screws. I've had other (cheaper, weaker) chairs where this is delivered as a single complete piece, or as pieces that slot together without screws. Each arm also has four screws - two attaching the separate pieces of the arm, and then two more to attach it to the seat. The design is also generous with spacers to support the screws - the arms have five spacers each.

However, the single most annoying part of assembling an office is attaching the back to the seat. Generally the attachment is purely with screws, so you have to fully hold two heavy objects close together in an awkward way while you get the screws in. I've done this many times with many chairs and it's always been a massive dreaded pain. This chair's different: the back slides onto a mount attached to the seat, and then, although it still isn't stable without screws, all you have to do is support it while you insert the screws. By reducing the difficulty of the SINGLE worst part of office chair assembly, this chair absolutely doesn't deserve any complaints about its assembly.

For the comfort and ergonomics, I only have one complaint: the arm rotation is adjustable and I have no use for that feature and only ever activate it unintentionally. This chair has a single control for the gas cylinder where a chair five times its price would have three other controls and position locks. Depending on your body type you might not find the dynamic lumbar support comfortable, but for me it's a very nice chair.

This chair is comfortable, has adjustable lumbar support, perfect for long days at the computer, with the ability to lay back and put your feet up on your breaks. I'd recommend this to everyone in search of a new office chair! :)

This chair is definitely the best! As a full time student, I spend most time sitting and studying. With this chair, my back pain has decreased.

This is the most comfortable chair I have. The lumbar is amazing. The price is also reasonable

Bought this on black Friday so get a big discount. I assembled it by myself and spent about half an hour. It is very comfortable after use for 2 months. You can adjust the headrest, armrest, position, and height of this chair. It moves very smoothly and silently with wheels.

Purchased to replace another chair that I use in my home office. The previous chair I had was a more traditional mid-back leather office chair. After sitting in it for extended periods the seat would cause my lower legs to ache. I have a mesh chair in my work office that I love. Since I first bought that chair it has increased to almost 600 dollars. I would have still purchased another for my home at that cost as I am very happy with it. While looking on I saw this chair recommended under other customers viewed. after looking at it and reading the reviews, it was similar enough to my office chair with an added lumbar support that I figured it worth a shot at almost half the cost. I have used it for more than a month since it arrived and I am very happy with it. It was easy to assemble and very comfortable providing good support while allowing extended periods in it without causing the leg fatigue of my previous chair. The only thing that I would wish for is a slightly wider seat. This being said it shouldn't be an issue for most as I am a fairly big guy at 290. Is it as comfortable as my work office chair, not quite, but pretty close. Definitely close enough considering the difference in cost. Had I never owned the other, I would have no complaints.

Very good quality and comfortable to sit on. I like their back cushion which supports my lumbar

This is a very comfortable chair for an 8 hour shift. Great support for my neck and upper and lower back.
