Sea to Summit Comfort Plus Mat

4 left in Johannesburg


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 independent high-resolution cell layers give excellent support by distributing your body weight and shape over more cells. The two layers are also offset for more uniform insulation and cushioning. Because the two layers can be pressurised independently, 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 fine tune valve to get just the right level of softness and support. All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.

Dual Layer Technology - Two layers of high resolution cells that can be pressurised independently: inflate the top layer to your personal comfort while maintaining a high-pressure base layer for protection for rough terrain.  Independent chambers allow the mattress to function even if one of the layers is punctured.


  • Double-layer Air Sprung Cells™ supports you with dozens of tiny flexing points instead of just a few large chambers, so you won't bottom out if you roll on your side
  • Each layer has its own valve; if you do end up with a puncture in one layer, the other layer remains fully functional
  • Each layer can be pressurized independently; higher pressure on the base protects against uneven terrain, while a lower pressure on top makes for soft sleeping
  • Offset dot-welds in the 2 layers deliver uniform insulation and cushioning
  • R-value of 2.5 means this mat is suitable for 3-season use; most sleeping pads we sell range in R-value from 1.0 (minimally insulated) to 9.5 (well insulated)
  • Multifunction valve allows quick inflation, deflation and fine-tuning of air pressure
  • Liquid thermoplastic polyurethane (TPU) lamination provides a stronger, more consistent bond than traditional roll-to-roll film lamination, eliminating delamination issues
  • Antimicrobial treatment is added to the TPU to prevent mold issues caused by warm, moist air trapped inside the mat
  • 40-denier ripstop nylon face fabric offers the right balance between weight and durability
  • Includes repair kit with 6 self-adhesive patches for fixing punctures in the field, plus a spare silicone one-way valve insert
  • For extended storage, the mat should be laid flat with valve open
  • Closeout
