Three decades after inventing the self-inflating mattress, Therm-a-Rest remains the most trusted name in outdoor comfort. They’ve maintained this position by continuing to offer users what no imitator can: unmatched quality. They make every mattress in their facilities in the U.S. and Ireland, using only the most reliable, innovative materials available. That’s why they can back up all their products with a lifetime warranty honoured worldwide, and why we can still say with confidence that beneath every great trip lies a Therm-a-Rest.
