Use

• High density convoluted foam is used in (or as an addition layer placed on top of) mattresses to provide additional support and comfort to the user. A foam overlay can also be used to protect damage and wear to a mattress to extend its use. It's also used to provide extra comfort to wheelchair users and campers.
  
  

Features

• The foam evenly distributes body weight across the surface, rather than falling into gaps on spring mattresses, to take pressure away from the body. Air circulation is also enhanced as air can get under the body and friction between the body and the surface beneath is reduced.
  
  

Cost and Availability

• Costs vary depending on the manufacturer, size and thickness of the foam. They can be purchased at retail stores an online.
