1. Types of Mattresses Anti-decubitus mattresses can be broadly classified into two categories static and dynamic. Static mattresses are typically made from high-density foam and provide consistent pressure relief; they usually range in price from $100 to $300. On the other hand, dynamic mattresses use air-filled cells that alternately inflate and deflate to provide a more active form of pressure relief. These mattresses tend to be more expensive, with prices ranging from $300 to over $1,500, depending on their complexity and features.
