The Sofa Sleeper mattress has been created with one goal in mind -- to provide you with the perfect sleeping environment.


Give your guests the best: Composed of 3 inches of polyurethane foam and 1.5 inches of memory foam, the mattress relieves the aches and pains associated with pressure and distortion during sleep. The mattress arrives compressed and rolled for ease of handling, so all you need to do is carry your new mattress to its permanent location, undo the tapes and remove the protective covering. In 30 minutes, the Sofa Sleeper mattress expands to 90% of its full thickness, and to 100% in 48 hours.


  • Compressed and rolled for your convenience
  • wake up refreshed
  • Free of aches and pains caused by pressure or distortion
