Big fan of this chair, almost fell asleep in it the other night! This may be user error, but the chair only seems adjust height with gravity- no hydraulic or spring system to lift the chair as far as I can tell- but after having this for a few weeks I realized I really don’t adjust the height of my chair very much ^_^ 
Not sweaty, good cushion, very comfortable. Recommended if you can’t or don’t want to spend crazy money on a gaming chair but spend most of your time in a computer chair or can’t sit in chairs normally.
