This four-season Therm-a-Rest air mattress offers unbeatable stability, warmth, lightweight comfort and lasting performance year-round. A patent-pending multiple-layer design of the NeoAir Reflective Barrier creates extra warmth by reflecting heat back to the user’s body and reducing convective heat loss to the ground.

In addition to minimizing air movement and convective cooling, the patent-pending Triangular Core Matrix creates an internal truss system that virtually eliminates the instability generally found on large tube-based air mattresses, assuring a more comfortable night’s sleep. More rugged fabrics provide added protection from four-season abrasion and abuse. No fiber or down insulation provides significant weight and space savings over any mattress with comparable warmth.


  • Year-round Warmth: Patent-pending design traps warm air to provide a high degree of warmth.
  • Light and Compact: NeoAir technology allows the All Season mattress to be lighter and more packable than mattresses filled with conventional insulation.
  • Extra Comfort: Stable construction and 2.5-inch thickness offer greater comfort for a full night of sleep.
  • Lasting Performance: The All Season mattress can be inflated directly without worry of exhaled moisture wetting insulation and decreasing performance.

About Therm-A-Rest:

Therm-a-Rest is part of a company named Cascade Designs, started by three friends and former Boeing engineers — Jim Lea, Neil Anderson, and John Burroughs — who were laid off from the aeronautics giant in 1971. Outdoor enthusiasts looking for the next great gear idea, they went on to design the world’s first self-inflating mattress, the Therm-A-Rest. Today, Cascade Designs remains a private, family-owned company that has grown to be one of the most respected outdoor manufacturers in the world.
