I am writing this review based on my wife's experience with the company. The chair that posturion.com is selling on their site actually belongs to a company called costway.com. Posturion.com has no mention that this chair is a costway.com chair. When we received the chair it was delivered in a costway.com box. There was about a $90 cost difference between the chair on posturion.com and costway.com.
My wife's concerns is not only the cost difference but the false advertising. Other online retailers disclose that they are selling a costway chair. It seems as if posturion.com is selling the chair as their own product.
