Make sure you know the difference of high back vs mid back versions
Color: Brown, Size: Mid Back
I got a little confused by the reviews since they mix the high back version with the mid back. I thought the arm rests were adjustable and the back had some lean. Apparently only the high back version. That said, it is very nice. Its at least a hundred less than what you'd get at an office depot and it is generously sized and very supportive and comfortable. The assembly was relatively easy, instructions could have been a bit better. The piece connecting the seat and back doesn't sit flush with the mount that attached to the legs which is weird but it feels sturdy nonetheless. Overall it's very nice and the design is really cool, it looks like a 70s race car style seat. Exactly what I was looking for basically. I sort of wish I got the high back version for the adjustable arms and the ability to recline but it is a work chair for me mostly so I guess it doesn't need to lean back, even if it would be nice if it did.

Excellent product. Great value, detailed parts and labels, outstanding construction.
Color: Brown, Size: Mid Back
Outstanding Purchase. The desk chair far exceeded my requirements and expectations. The price was so far below other office chairs that I was concerned that it would be shoddy, uncomfortable, cheap looking and impossible to put together. Materials were top grade, instructions were precise and all parts were market for location with "front and back" labels. Not a screw was missing or misaligned. Since my desk and office are in the Master, really impressed with the color and design. Very comfortable with good back support ,adjustment ease and arm support.. Bravo to your team!!!

Lovely and comfortable
Color: Brown, Size: Mid Back
Well made and easy to put together. I bought 2 and found them both to be well worth the money. You can tell the quality is there vs. other chairs I’ve bought online before.

Smooth!
Color: Brown, Size: Mid Back, Color: Brown, Size: Mid Back
Good value and looks pretty good. Faux leather feels like Naugahyde. Should be durable since that's what boat seat are made of. Could use a bit more lumbar support, but overall quite comfortable. Wider than I expected (so it must be designed for us Americans.) Casters are fantastic. Far superior to traditional plastic casters. Because these are made of rubber, they are dead quiet and smoooooth rolling across the flooring. Took about 30 minutes to assemble. Lots of parts but the pictorial instructions were clear. I'd give it five stars, but I wish it had a bit more height adjustment. We'll see how it holds up, but so far I'm pretty pleased.

Very pleased with my purchase
Color: Brown, Size: Mid Back
Easy to put together - instructions are good - excellent quality and the chair is comfortable. Far from being flimsy it's a heavy chair which rolls perfectly as needed. You won't find that many good chairs (if any!) at this excellent price. As always the ultimate question is: would I buy it again? The answer is YES, definitively. Great purchase.
