    I was surprised by just how firm the support in this chair was without it being hard as a rock or comfortable to sit in long term.I have a desk job that often has me tied to my chairs for hours at a time. In that situation it means I need ti make sure any chair I have supports my lower back and this one does that very well.

    My grandson desperately needed a new desk chair. His gaming chair fell apart and I decided (since he lives with me) to get him this chair as an early Christmas present. The second it arrived, he brought it up to his room and assembled it. Assembly was easy enough and he had it together in about 20 minutes. He loves it! He said it's more comfortable than his gaming chair. Sturdy, durable, and well made. Highly recommend.

    I'm writing this review after daily driving this chair for over a month and a half now. I'm surprisingly surprised at how good this chair feels! The mesh circulates air to your back and bottom and it keeps it cool. Also there's support in all the right areas. I can sit in it for hours and not feel much discomfort. The arms are a hard plastic though so that may turn some people off but honestly most of the time my arms are near my desk so I don't use the arm rests much. The only thing I don't like about this chair is that it does creak and crack due to a mostly plastic construction. It's a bit of a minor complaint. I changed wheels to better clear rubber ones to not scuff up my floor. I think this chair is great! super comfortable and very supportive. I am extremely pleasantly surprised given the price range. I think buying super expensive chairs give incredibly diminishing returns in the end. This chair really fits the bill for me.

    I got this to replace a gaming chair that was beginning to come apart. It could not withstand a full time work schedule of use. This chair does not have the typical foam cushion seat. It has tightly stretched woven mesh. It is actually more supportive than it looks. The flip up armrests are genius! I don't have to adjust my seat height to push the chair in ever. If I could have a wishlist item, it would be adjustable back height. The lumbar support falls just short of where I really want it to be. Overall, this chair is supportive and it's unique design feels like it moves with me. So far, it's comfortable and holding up well.

    This lightweight easy rolling office chair is very comfortable and adjustable. It took about 15 minutes to assemble with clear instructions. The seating area of the chair is all mesh and sits comfortable. Since it is a mesh it's perfect for those people who tend to get hot or sweaty in a leather or leather-like chair. Very pleased with this chair, great product!
