This chair is a great buy and comfy too. I use it for free-motion longarm quilting and needed the position of the seat to allow me to lean forward. It keeps my back in alignment while allowing me the reach I need. The seat has just the right cushion too it. The wheels move along the tile floor when I want them too, but I don't scoot around when I don't want to move. That was important to me too since I must have a stationary seat when moving the machine around. I love everything about it.
