Insulation and test basis
Check the published R-value and its test basis. Thickness and a soft surface do not establish how well a mat insulates.

Sleeping mats buying advice
Before you buy
Width where you need it
Compare shoulder width, length and shape with your sleep position and tent floor. Wide mats can change how many sleepers fit.
Your transport and repair plan
Check packed dimensions, weight, valve type and compatible repair supplies. A comfortable car-camping mat may be bulky for backpacking.
From first use to the next trip
Use, care & repair
01Check before a trip
Inflate as instructed and test the mat overnight at home. Inspect the valve and surface, and locate the model-specific repair instructions.
02Protect the surface
Clear sharp objects and follow inflation limits. Use only a compatible pump or inflation sack; do not assume every adapter fits.
03Store for the construction
Clean and dry as directed. Air mats and self-inflating foam mats can have different long-term storage and valve-position requirements.

Read the guideCommon buying questions
Good to know
Is a thicker mat necessarily warmer?
No. Check a published insulation value and its test basis rather than using thickness as a warmth rating.
Will two wide mats fit my tent?
Compare their actual dimensions with the usable inner floor, including tapered corners and door space. Nominal person ratings are not enough.
Does losing firmness overnight always mean a puncture?
Not always. Temperature changes and valve issues can also affect firmness. Use the manufacturer's troubleshooting procedure before choosing a repair.
