First things first. The butt part isn't very cushiony. I added a cushion. With a cushion for your butt, the chair is comfortable and the back hits in a good area. It is not a very big chair, but it is absolutely perfect for what I needed it for. VR GAMING.
I wanted to be able to play certain games sitting, due to getting dizzy with fast locomotion in game/flying/zero gravity situations and having something solid at my lower back makes a huge difference. I would play on the couch, but you can't spin around and it limits arm movement. This chair solved it. I can spin and swing in every direction and keep myself inside my "play area" so I don't knock anything over while in the virtual world.
It arrived quickly and was the easiest chair I ever put together. It has wheels, spins, goes higher and lower, and has no arms. Exactly what I was looking for. It's a great little chair for gaming or crafts. It does not have a big footprint and can easily be moved around from room to room. If you want to sit for long periods, get some kind of posterior support. Your butt will thank you because that is my only complaint, the bottom area is little to no padding.
