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.
