5 Best RV Full Mattress in 2026: A Practical RV Guide

Full and short full memory foam mattresses for RV and camper beds compared for thickness, cooling and size, so you buy the right 54 or 48 inch width.

By Bowen HigginsRV Editor at RV Gear Lab5 products comparedSpec-sheet researched

RV full beds come in two widths, a short full at 48 by 75 inches and a household full at 54 by 75, and mixing them up is the most common buying mistake. This guide covers five full-size memory foam mattresses, one made for RVs and four household fulls that suit larger rigs. Measure the platform width before you pick.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: INEHM Short Full Mattress leads this shortlist for Narrow RV beds. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are 48 by 75 inch short full, 8 inch memory foam. Confirm the exact model and included components before ordering.
Trade-off to plan for: Short full size limits sources for replacement

Before you buy

What Matters Before You Choose an RV Full Mattress

Key buying criteria so you get the right fit the first time.

01
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.
02
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.
03
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.
04
Certified materials
CertiPUR-US and OEKO-TEX refer to foam content and fabric testing. Not every listing names them. Check the bullet points.
05
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.

Methodology

How We Built This Shortlist

Each pick was assessed across 4 criteria weighted for real-world use.

Width fit

We compared 48 inch short full and 54 inch full sizing, since width decides whether a mattress fits an RV platform.

Foam depth

We compared 6 and 8 inch builds for comfort versus headroom.

Cooling

We noted gel and cooling designs, which matter in small warm spaces.

Certifications

We noted which listings name CertiPUR-US or OEKO-TEX.

FAQ

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.
