The Comfort Plus SI series combines the comfort of a 3 inch air mattress with the support and self-inflating performance of a foam core - without the expected weight penalties. This is made possible by our patent pending Delta Core™ technology, which removes the optimal amount of foam without sacrificing support or durability. A luxurious 30D stretch knit fabric is used on top for a soft next-to-skin feeling. Lightweight 30D polyester with extrusion laminated TPU is used on the base.


  • Utilizes Delta Core™ technology, which removes the optimal amount of foam to ensure light weight and reduce the packed volume without sacrificing support or durability
  • Multi-function, patent-pending multi function valve twists over to allow the mat to be rolled tightly without fighting re-inflation as you go
  • Provides 3 inches of support for a comfortable night’s sleep
  • Diagonal supporting foam "walls" help inflate the mattress and creates a more compact rolled mat
  • Equivalent R-Value of 4.1 insulates you well into the shoulder seasons
