Buying Guide

Confirm RV bed dimensions

Measure mattress length, width, and corner shapes before buying; RV and bunk sizes (e.g., 30x72 or 36x72) differ from standard home mattresses

Choose appropriate thickness for clearance

Pick a mattress thickness that fits under cabinets and entryways—many RV foam mattresses are 6–7 inches to balance comfort and space constraints

Prefer lightweight, dense foam

Memory and gel-foam offer pressure relief while staying lighter than innerspring options, which helps with handling and reduces strain on RV supports

Look for gel additives for temperature control

Gel-infused memory foam can help dissipate heat better than standard foam, improving sleep comfort in small, warm cabins

Check firmness and support level

Select medium-firm options for general support in a confined sleeping surface; firmer foams help maintain spinal alignment on thinner RV mattresses
