This provides you with a cool plush feel. Whether you are sleeping or just relaxing you will rest in comfort. Our special layered design starts with soft foam on top and graduates to a firmer foam on the bottom. This creates a 8″ deep mattress to make you feel right at home in your Peterbilt, Kenworth or Freightliner truck.
