Its comfortable breathable and no lumps from any soft covered chair... its awesome. I love the lumbar support and the head rest great chair. I would recommend to everyone who has a desk job and is sitting for the majority of their work day!
I put the chair together myself and it was simple until the final step - attaching the seat/back to the base. The seat/back is quite heavy once it's all assembled and was a bit awkward to attach but I got it. I do like the chair a lot - it's very sturdy and I don't get hot sitting on it because of the mesh. This is a professional office type of chair and I'm very glad to have it especially after 10 solid months of teleworking every day - with no change in the foreseeable future. My home office is pretty small and I've avoided this type of a chair because of that but this chair is making a world of difference for me. I'm very relieved that I finally made this purchase.
Chair comfort will not be mistaken for an Aeron but the price point is much lower! As others have noted the lumbar suppport does not really want to stay in place. This might be due to height (6'1") or weight (230#) but it is the only negative I see (not that big of a deal). Overall pleased with purchase!
the chair is designed to allow you to be sitting for long periods of time without pain however the controls are very basic and the materials are very cheap. the chair looks bulky and ugly
