I purchased it as a gift and they absolutely loved it. It’s the mesh for me that helps keep the body cool. I’m 50/50 about the head rest but it is detachable.
Its a pretty good chair. Most of my grievances are with the lumbar support cushion though which is very important to me as i am an artist and I sit at my desk doing work for hours at a time and i need good lumbar. The cushion is too far low into the seat. It pushes into my lower back instead of fitting to the natural curve of my spine. It does adjust but it never says where you adjust it and it falls to the bottom within seconds of you sitting in the chair. I had to super glue it into the highest position. And for anyone curious im not a tall guy im 5'6 so its not an issue of me being "too tall" for the lumbar. The head rest is great tho and it's a comfortable chair. Really a shame the back support cushion is lacking because otherwise would be a fantastic chair
