Thermarest

Invented in the early 1970s by two former engineers and avid backpackers, a Therm-a-Rest air mattress consists of an airtight nylon fabric envelope filled with a sheet of low density, open-cell polyurethane foam.

When a valve is opened, the foam expands and draws air into the mattress. When the mattress has fully inflated the user simply closes the valve. To pack the mattress the valve is opened and it is rolled up tightly to force the air out, whereupon the valve is closed to prevent re-inflation.

They continue to develop the concept with lighter, warmer models and luxury that even approachs a night in your own bed! Lifetime guarantee and a full repair and accessory range to give you the confidence to trust in your purchase.
