About Therm-a-Rest
Therm-a-Rest invented the self-inflating sleeping pad in Seattle, Washington in 1971, and has remained the standard for backcountry sleep systems used by mountaineers, backpackers, and outdoor professionals worldwide.
Heritage & History
Therm-a-Rest was created by Cascade Designs in Seattle, Washington in 1971, when John Burroughs and Neil Anderson developed the first self-inflating sleeping pad. The invention solved a fundamental problem in lightweight backpacking: foam pads were bulky and heavy, while air mattresses were fragile and required manual inflation. The self-inflating pad used open-cell foam that expanded automatically when a valve was opened, combining the insulation of foam with the compressibility of an air mattress.
The original Therm-a-Rest design was patented in 1972 and became the standard sleeping pad for serious backpackers within a decade. Cascade Designs has continued developing the technology from its Seattle facility, introducing each generation of improvements from reflective insulation layers to triangular baffle systems that maximize warmth-to-weight efficiency.
Made in Seattle, Washington
Cascade Designs manufactures Therm-a-Rest sleeping pads at its Seattle facility, where the foam cores are produced, the inflatable systems are assembled, and the quality testing is conducted. The Seattle location has been the engineering hub for every major Therm-a-Rest innovation, including the ThermaCapture reflective barrier that dramatically improved the R-value of ultralight inflatable pads without adding meaningful weight.
The Z Lite foam pad, a bestselling ultralight option, is cut and finished in Seattle from the company's proprietary closed-cell foam formulation. The NeoAir inflatable series uses a triangular core matrix of internal baffles — a Seattle-engineered solution to the problem of sleeping pads that collapse sideways and leave sleepers resting on the ground.
