Sea to Summit Comfort Plus Sleeping Mat - Tapered Regular



Item #: 331792674

Our Comfort Plus sleeping mats with their dual layer construction provide the most effective system for fine-tuning the level of comfort available in any air mattress today. The two independently pressurized chambers of high-resolution air-sprung cell cells give excellent support by distributing your body Weight: and shape over a large number of independent cells. The cells are offset: a cell on the top layer coincides with a weld on the lower for more uniform support and greater insulation. The top layer can be inflated to your personal comfort, while maintaining a high-pressure base layer for protection from rough or uneven terrain. Both layers can be adjusted independently using the multi-function valve to get just the right level of softness and support.

NOTE: Find in Store Inventory levels are continuously changing. Please contact store to confirm availability is as shown.


  • The Comfort Plus Regular tapered shape is designed with 548 Air Sprung Cells and the regular rectangular shape is designed with 596 Air Sprung Cells. These revolutionary Air Sprung Cells™ are formed by a matrix of dot welds and function like individual coils in a pocket-sprung mattress for unrivalled support and comfort
  • The dot welds are offset to provide the highest resolution of Air Sprung Cells
  • Dual layer design ensures a level of built-in redundancy; if a puncture occurs in one layer of the mattress, the other layer remains fully functional
  • Because the two layers can be pressurized independently, the top layer can be fine-tuned to your personal comfort, while maintaining a high-pressure base layer for protection from rough or uneven terrain
  • Patent-pending multi-function valve for really fast and easy inflation, deflation and fine tuning of air pressure
  • 40D rip-stop nylon face fabric offers the right balance between Weight: and durability
  • Unique aeronautical manufacturing technology: liquid-extruded TPU bonds permanently to the shell fabric, virtually eliminating delamination
  • An anti-microbial treatment is added to the TPU to prevent issues caused by warm, moist air trapped inside the mat
  • All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches and a spare silicone one-way valve insert
  • Inflation with one of Sea to Summit’s optional pumps (Jetstream or Airstream) takes only 30 to 60 seconds; mouth inflation incredibly requires only 8-12 full breaths. Deflation takes moments
