How to choose camping mattresses
Thickness
Three to four inches of loft is where most side sleepers stop feeling the ground. Self-inflating foam mats feel the most like a real bed.
R-value (warmth)
R-value measures insulation from the ground. R 3 is fine for summer; aim for R 6 or higher for spring and fall nights.
Air, foam or hybrid
Air mattresses pack smaller and are lighter. Foam and self-inflating mats are quieter, warmer and less bouncy, but they take more room in the car.
Size
Measure your tent floor or cargo area before buying a double. Wide mats over 50 in may not fit smaller tents.
FAQ
What R-value do I need for camping?
R 2–3 for warm summer nights, R 4–5 for three-season use, and R 6+ for cold shoulder seasons or winter.
Can I use a camping mattress for backpacking?
Usually not. Most weigh 3–10 lb. Backpacking pads weigh 1–2 lb but are thinner.
