Double Self Inflating Mats

About

A good night's sleep makes or breaks a camping trip. Our range of double self inflating mats — also known as double SIMs — gives couples and families the insulation, comfort and convenience of a wide, cushioned sleep surface without the bulk of a traditional airbed. Unlike inflatable airbeds that rely purely on air pressure, self inflating mats contain open-cell foam that expands automatically when the valve is opened. The foam provides structure, warmth and support even if the mat isn't perfectly inflated, making them significantly more comfortable and reliable for regular camping use. We stock double self inflating mats from Vango, Outwell, Kampa and Outdoor Revolution — all available with free UK mainland delivery on orders over £100, next day delivery if ordered before 1pm, and our price match guarantee. Popular models The Vango Shangri-La 16 Lux Double is our best-selling double SIM. At 16cm deep with high-density foam and a plush comfort topper, it delivers a near-bed feel inside a tent. It's the go-to choice for couples who camp regularly and want to wake up genuinely rested. Dual valves make inflation quick and easy, and the anti-slip base keeps it firmly in place overnight. The Outdoor Revolution Camp Star 100 is a 10cm double self inflating mat that strikes an excellent balance between comfort and practicality. It's well suited to couples camping in family tents or awnings, offering great cushioning and ground insulation without being overly bulky to transport. How to choose the right double self inflating mat Thickness is the most important factor. The thicker the mat, the more cushioning between you and the ground and the better the insulation. For occasional summer camping a 7.5cm mat is fine. For regular camping, harder surfaces or cooler conditions, we'd always recommend 10cm or above. If you want genuine luxury comfort, the Vango Shangri-La range at 12cm is in a class of its own. Insulation matters as much as cushioning. Cold ground pulls heat from y
