The Thermarest Self Inflating Mattress, the first of it’s type in the world.

Designed by former engineers of Boeing Company Aerospace Corporation Jim Lea, John Burroughs and David Burroughs. First designed in the late 60’s to the early 70’s, the idea sprung to mind when co-founder Jim was kneeling down tending to his garden on an air mat. The way the pillow distribute air evenly and also kept his knees off the ground gave him a light bulb moment and it wasn’t long until they had invented the thermarest self inflating mattress.

Trying to get a good nights sleep on the cold hard ground is often a challenge on its own. In my opinion one of the most important things you need to bring on a camping trip is a decent ground mattress.  After 40 years in development, Therm-A-Rest self inflating mattresses is the world’s leading brand in the outdoor industry. See below for the different types of technologies Therm-A-Rest™ have to offer.

Years of research has been put into these ground mattresses, ensuring the quality these mats are built to reach the highest standards and uses the best materials. In addition, every Therm-A-Rest inflatable Mattress comes with a life time manufacture’s warranty. Each individual mattress is toughly tested to the highest standard.

Rapidly expanding Cascade designs have based Therm-A-Rest in Ireland.

With manufacturing being carried out close to home in Middleton, county Cork, Ireland and further afield in Seattle USA, Therm-A-Rest find that having a European and American base can keep the cost of these innovative mattresses at a reasonable price.
