What Matters Before You Choose an RV Full Mattress
Key buying criteria so you get the right fit the first time.
Short full or full
A short full is 48 by 75 inches and a full is 54 by 75 inches. A full mattress on a short full platform overhangs by 6 inches. Check your platform before ordering.
Mattress thickness
Eight inches is more comfortable than six, but it raises the bed and cuts headroom. Match thickness to bunk or loft clearance. Read the inch figure in the title.
Cooling features
Memory foam traps heat, which is amplified in a small RV. Gel infusion and breathable covers reduce it somewhat. Look for the words cooling gel in the title.
Certified materials
CertiPUR-US and OEKO-TEX refer to foam content and fabric testing. Not every listing names them. Check the bullet points.
Trial and warranty
Boxed mattresses are hard to test in a store. A trial period lets you return it if it does not suit. The INEHM lists a one-year trial.

Before You Bring One Home
What is the difference between a short full and a full?
A short full is 48 by 75 inches and a full is 54 by 75 inches. RV beds often use the short size. Measure your platform width to decide.
Can I put a household full in an RV?
Yes if the platform is 54 inches wide. In a narrower bed it will overhang. Check the width first.
Is 8 inch foam better than 6 inch?
It is more cushioned, which suits heavier sleepers and nightly use. Six inch suits guest beds and low headroom. It depends on your clearance.
How long should I wait before sleeping on a boxed mattress?
Let it expand as the listing directs, often several hours. Follow the product guidance.
