These chairs are great as a start out chair I think, but I definitely plan to replace them at a later time when I am able. The hydraulic pump doesn't go up much at all, and for someone who is 5' 10" like myself, that was a little disappointing. Also, when you release the pump, the chair falls all the way to the ground, causing the foot rest to hit the floor. Lastly, don't get white. While it looks nice I've literally had two people sit in the chair and the seat already has some staining just from their black leggings and blue jeans. Also when I received the items, one of them had dirt markings on it, and the covers I also purchased had discoloration.
