Camping sleeping mats

Guide

Camping sleeping mats

A sleeping mat separates you from cold ground and smooths out uneven surfaces. Insulation, sleeping comfort and packed size are separate properties to compare for your trip.

Key points

R-value describes insulation, rather than thickness alone.
Side sleepers need enough room at the hips and shoulders.
Foam works without inflation but takes more packing space.
Air mats need suitable valves and repair equipment.

Common questions

Is a thick mat warmer?

Not necessarily. A thick air chamber may be comfortable without providing much insulation. Compare the stated R-value for the exact size and construction.

Do I need a layer underneath?

A clean, smooth pitch protects the fabric. A suitable ground sheet may help on rough ground, but remove sharp stones and twigs before lying down.

Can I combine two mats?

Yes, for example foam beneath an air mat. Check that both stay in place and fit the tent. This also increases the packed size and weight of your sleep system.

How should I store a mat?

Clean and dry, following its instructions. Self-inflating mats are often stored with the valve open; air mats may have different requirements. Never roll up damp fabric for storage.
