Self-Inflating Sleeping Mats

How does a self-inflating mat work?

When you open the valve, the foam inside expands and draws in air: the mat inflates almost entirely on its own, before a few extra breaths top it up to adjust the firmness. This system combines the insulation of foam with the comfort of air: a balanced, easy-to-use compromise that's a firm favourite for wild camping and campsite trips alike.

Insulation and comfort

The internal foam layer provides good insulation from cold ground, while the air gives a plusher feel than a simple mat alone. It's a comfortable mat, thicker than foam alone, suited to most seasons. Paired with a good sleeping bag, it guarantees warm nights.

Weight, pack size and use

A touch heavier and bulkier than an ultralight inflatable mat, a self-inflating mat remains perfectly reasonable for trekking and really comes into its own for car camping or campsite stays. It's also quicker and simpler to set up. To weigh up the pros and cons, browse our trekking and camping mats.

Care and lifespan

Like any inflatable, it can get punctured: a repair kit and a bit of care are all you need to keep it going. Store it flat with the valve open to prolong the life of the foam. It's a reliable classic that holds up season after season. The quality of thermal insulation and sleeping comfort are what make a self-inflating mat worthwhile: balanced, simple and dependable kit for most seasons.
