Self Inflating Mattress

A self inflating mattress offers the ideal balance between air pad lightness and foam mat insulation. Open-cell foam expands when unrolled, drawing air in automatically for hassle-free setup at camp. Combined with genuine thermal insulation from the foam core, these mattresses provide reliable warmth and stability on cold ground—whether you're bivouacking on Dartmoor or car camping in the Scottish Highlands.

How to Choose a Self Inflating Mattress

The R-Value measures insulation from cold ground. For three-season UK camping (spring through autumn), look for R3 to R4. Winter hillwalkers and wild campers in exposed conditions benefit from R4.5 or higher. Summer-only use requires R2 at minimum.

Mattress thickness typically ranges from 2.5cm to 10cm. Thinner models (2.5–5cm) suit backpackers prioritising packed weight. Thicker options (7–10cm) favour car campers and base camp users who value sleep quality over portability. Side sleepers generally need 5cm or more to prevent hip and shoulder contact with the ground.

Backpackers should consider weight carefully—lightweight self inflating mattresses start around 500g for compact models. Car campers can opt for heavier, more luxurious options without penalty. Check packed dimensions if your rucksack space is limited; some models compress smaller than others.

Self inflating mattresses use durable outer fabrics that resist punctures better than pure air pads. Look for ripstop nylon or polyester shells with reinforced seams. Most can be field-repaired with standard patch kits if damaged.
