Therm-a-Rest discount codes & offers

Therm-a-Rest is the sleeping-pad brand of Cascade Designs, based in Seattle, and it is credited with inventing the self-inflating sleeping pad in 1972. Its range runs from closed-cell foam mats and ultralight NeoAir air pads to deep self-inflating mattresses for car camping, and every pad it sells today descends from that first foam-and-air idea.

Where to buy in the UK

There is no Therm-a-Rest shop for British buyers: the brand’s UK pages redirect to a Cascade Designs store that serves the United States. UK campers buy from outdoor retailers instead, including Facewest, Base Camp Food, Absolute Snow, Trekitt and WildBounds, and prices can differ from shop to shop. The Camping and Caravanning Club lists the MondoKing 3D at £216.75 and the NeoAir Venture at £100 in its guide to camping mats.

Guarantee

Facewest lists the MondoKing 3D Large at £216.75, with the XXL a little dearer. On its warranty page Therm-a-Rest offers a limited lifetime warranty on all products except electronic devices, which carry a 2-year limited warranty. In the UK a claim usually starts with the retailer you bought from. The MondoKing 3D, an 11cm self-inflating mattress with an R-value of 7.0, is ranked in our camping mattress comparison.
