by RV mattresses are one of the most confusing mattress categories because they use non-standard sizes with names that sound familiar but aren't. An RV short queen is not a queen. An RV king is not a king. This guide explains every RV mattress size, the best materials for travel use, and how to find the right replacement for any RV type.

All RV Mattress Sizes
RV sleeping platforms come in 7 common configurations, none of which match standard home mattress sizes:
| RV Size Name | Dimensions | Standard Equivalent |
|---|---|---|
| RV Short Queen | 60" x 75" | Queen (60x80") — 5" shorter |
| RV Queen | 60" x 80" | Standard Queen (exact match) |
| RV King | 72" x 80" | King (76x80") — 4" narrower |
| RV Short King | 72" x 75" | King — narrower AND shorter |
| RV Full | 53" x 75" | Full (54x75") — 1" narrower |
| RV Twin | 38" x 75" | Standard Twin (exact match) |
| RV Bunk | 28" x 75" | No home equivalent |
Short Queen: The Most Common RV Size
The short queen (60"x75") appears in the majority of Class A motorhomes, most Class C slide-outs, and many fifth wheel front bedrooms. When RV owners search for a replacement mattress, short queen is the correct starting point — but always measure your specific platform, as some manufacturers use 58"x74" or 60"x74" and call it "short queen."
Why Foam Beats Springs for RV Use
The vibration from road travel creates a constant low-level stress on mattress internals. Steel coil systems — both innerspring and pocketed coil hybrids — develop squeaks and lose tension faster in vehicles than in stationary homes. Foam mattresses have no moving parts to loosen, making them objectively better for RV use on four dimensions:
- Vibration dampening — foam absorbs road vibration rather than transmitting it
- Weight — foam mattresses weigh 30–50% less than comparable spring alternatives
- Durability in motion — no mechanical components to fatigue
- Custom cutting — foam can be cut to exact non-standard dimensions easily
Best RV Short Queen Mattresses
1. RV Mattress by Innerspace Luxury Products — Best Purpose-Built
Innerspace specializes exclusively in RV mattresses — available in every standard RV size including custom dimensions. Their 10-inch gel memory foam short queen is the top-rated option among Class A owners. Ships compressed, weighs ~40 lbs.
2. Zinus Cooling Gel 10-Inch (custom cut) — Best Budget Custom
Standard Zinus can be ordered directly from the manufacturer in custom sizes for a modest upcharge (~$50–$80). For exact non-standard dimensions, this is the best value approach.
3. Brentwood Home Cypress Eucalyptus — Best Organic Option
Brentwood's short queen option uses CertiPUR-US foam and Tencel fabric — preferred by owners who spend extended time (weeks+) in their RV and prioritize air quality in enclosed spaces.
4. Classic Brands Gramercy 14-Inch Hybrid — Best for Full-Time RVers
Full-time RV residents who park for extended periods may justify the hybrid's superior comfort. At 14 inches, verify your RV bedroom platform accommodates the height. Pocketed coils provide better edge support for getting in and out in tight RV spaces.
Measuring for RV Mattress Replacement
- Remove the existing mattress completely
- Measure the bare platform at its longest and widest points
- Note any obstacles (slide rails, storage drawers) that constrain the mattress perimeter
- Measure the clearance above the platform to determine maximum thickness
Add 0.5 inches to each measurement for ordering — a slightly oversized mattress can be trimmed; an undersized one creates uncomfortable gaps.

Frequently Asked Questions
What size is an RV short queen mattress?
RV short queen mattresses measure 60 inches wide by 75 inches long. A standard home queen measures 60x80 inches — the RV short queen is 5 inches shorter to fit the compressed sleeping quarters in most Class A, B, and C motorhomes.
Can I use a regular mattress in an RV?
Only if your RV sleeping platform matches a standard mattress size. Most RV bed platforms are non-standard — short queen (60x75"), RV king (72x80"), RV bunk (28x75") — requiring RV-specific mattresses.
What is the best mattress material for an RV?
Foam (memory foam or poly foam) is the dominant RV mattress material for two reasons: lighter weight than spring alternatives, and better vibration dampening during travel. Gel-infused foam addresses the heat-trapping issue common in compact RV spaces.
How do I measure for an RV replacement mattress?
Measure the sleeping platform length and width at its widest and longest points. RV manufacturers sometimes use non-standard dimensions even within "short queen" classifications — actual measurement is more reliable than assumed size.
What is the thinnest comfortable RV mattress?
6-inch foam mattresses represent the floor for comfort in an RV context. Under-bed storage in many RVs limits maximum thickness to 8–10 inches. Gel memory foam at 8 inches is the most common RV owner choice.
