Frequently asked questions
How thick should a camping foam mattress be?
For adequate comfort on uneven ground, at least 4 inches thick is recommended. Thicker mattresses (5-6 inches) provide extra cushioning for side sleepers. Consider thickness against pack size if you have limited space.
What certifications should I look for in a camping mattress?
Look for CertiPUR-US and OEKO-TEX Standard 100 certifications. CertiPUR-US ensures foam is free from ozone depleters and heavy metals, while OEKO-TEX verifies fabric safety. These certifications indicate product safety and durability.
Is memory foam good for cold weather camping?
Standard memory foam can stiffen and lose comfort in cold temperatures. For cold weather camping, choose foam with a high R-value (above 5) or a hybrid design. Avoid pure memory foam for sub-freezing use unless it's rated for low temperatures.
How do I clean a thick foam camping mattress?
Use a mild soap and water solution with a soft cloth to spot clean. Avoid soaking the foam. Most covers are removable and machine washable. Always dry thoroughly before storage to prevent mold.
Can I use a camping mattress as a permanent bed?
Yes, many tri-fold mattresses double as guest beds or temporary daily use. However, thicker, high-density models (like the Milliard) hold up better over time. For permanent use, consider a mattress with a 30-day trial and good warranty.
The verdict
The Milliard Tri-Fold Mattress is our overall winner for its portability and firm support. For cold-weather vehicle camping, choose the Hest Foamy with its high R-value. Budget campers will appreciate the EPEVA 4 Inch for its low cost and decent comfort.
