This chair works well for 3-4 months and then it goes bad after that. The hydraulic pump will give out so any time someone sits in the chair, it will drop slowly until it has reached the base. The netting part of the chair will become weak so if someone is sitting in the chair their spine will touch the plastic support and it is very uncomfortable. Even when this chair was in its prime, it was definitely uncomfortable. I would stay away from this chair, but if you still go through with it, buy the extended warranty since it will break after the grace period and you will have to plead with Wayfair in order to get replacement parts.
