An orthopedic mattress (or orthopaedic mattress) is a mattress designed to support the joints, back and overall body. As its name suggests, an orthopaedic mattress has been influenced by the medical study of orthopaedics which focuses on disorders or deformities of the spine and joints. Orthopaedic mattresses have been created to combat the problems one might experience with a bad back or joints by providing a firm mattress which offers targeted, tailored support.
