2023’s best sleeping mats

Featured mat: Therm-A-Rest NeoAir XTherm ($599.99). Distributed by

No sleep system is complete without a sleeping mat – it’s as important as the sleeping bag in ensuring you stay warm and comfortable through the night. Choose a mattress based on the temperatures you most often camp in.


A sleeping mat’s R-value (Resistance-value) measures its effectiveness at resisting heat loss. The higher the R-value, the warmer a mattress will be. The international ASTM F3340-18 standard ensures all mattresses are tested in the same way to achieve consistent R-values across brands. It makes it easier for consumers to properly compare and judge the warmth of various mattresses.

Here’s a basic guide to give you an idea of what to expect from each R-value:

  • R1-R2: For summer use when day and nighttime temperatures are warm.
  • R2-R4: Suitable for three-season use, including conditions where there might be a mild ground frost.
  • R4-R6: All season use, including conditions where there could be a heavy ground frost.
  • R6+: Below freezing air temperatures day and night, with cold to frozen ground.


Foam-filled mats are self-inflating, drawing air in as the mat regains its unrolled shape. Synthetic and down-filled mats will come with an inflation sack to ensure moisture from your breath doesn’t get inside. Air-filled models only need your lungs to inflate.

Fabrics and finishes

Fabrics are patterned and coated to provide grip so the user doesn’t slide off during the night. They are DWR-coated to provide water resistance.


Store the mat in a cool, dry place, unrolled, with the valve open.


Generally speaking, the thicker a mattress, the warmer it will be.


Controls airflow in and out of the mat. Some mattresses have two valves; one used to inflate and the other to deflate.

Shape and size

Most mats come in short, regular (or medium) and large sizes. They can be tapered to save weight and bulk and to make laying two mats side-by-side easier. Shorter, tapered models are perfect for summer camping while winter models will be full-length. Prices vary depending on size.


High-density open-cell foam, thermal heat-reflective linings and down or synthetic-insulation are the warmest mattresses because they slow convective heat loss into the ground. Air-filled mats are less warm, but they are also lighter.
