Therm-a-Rest is an American outdoor product company specializing incampingmattresses,sleeping bags, camp chairs, cots, and pillows. Therm-a-Rest began as a line of self-inflating camping mattresses, invented in the early-1970s by two formerBoeing engineers and avidbackpackers. The company was initially namedCascade Designs, which is now the parent company of Therm-a-Rest[1] and other outdoor brands.
A Therm-a-Rest self-inflating mattress consists of an airtightnylon fabric envelope filled with a sheet of low density, open-cellpolyurethane 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 increase firmness a few breaths of air can be blown into the mattress. 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.[citation needed]
