We’ve addressed Moisture control by channeling air flow within the mattress. By cutting areas between the memory foam and the polyurethane foam, air can travel through the bed allowing it to breathe. The result of these air channels, coupled with our Serene foam, is drier skin and drastically improved temperature control. The borders of the Linebacker Mattress use green spacer cloth, very similar to the material used in running shoes. This material allows air to move in and out of your mattress to keep your skin cooler and mainting proper temperature control.
