Frequently asked questions
What certifications should I look for in an RV mattress?
Look for CertiPUR-US (foam safety and durability) and OEKO-TEX (absence of harmful substances). These ensure the mattress is free from chemicals and meets safety standards.
How important is thickness for an over-cab mattress?
Thickness impacts comfort and support. A 5- to 6-inch profile is common for over-cab spaces. Thicker mattresses may not fit the overhead cab's curvature, while thinner ones may lack support.
Can I use a standard home mattress in my Class C RV over cab?
Possibly, but standard sizes often don't fit the odd dimensions of over-cab bunks. Custom RV-specific mattresses are better to avoid gaps or overhang.
How do I measure for an over-cab mattress?
Measure the width, depth, and height of your over-cab space at multiple points. Account for any curvature or corners. Many mattress brands offer custom sizing based on your measurements.
Do RV mattresses off-gas like regular memory foam?
Yes, some RV foam mattresses off-gas initially. To minimize this, choose CertiPUR-US certified models and air them out for 24-48 hours before use.
