After one year of owning the ErgoChair Pro, this chair is very uncomfortable. The cushion is mediocre at best and the armrests are very squeaky. I can no longer make it through an 8 hour day sitting in this chair and at night the loud squeaky sounds sometimes wake my wife up in the next room.
Although it looks cool, it really is not worth the price compared to the cheaper chairs I have owned. I now have neck and back pains after using this chair and this is something that I have never experienced with chairs that do not claim to be ergonomic.
