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.
