RV mattresses aren't standard sizes, and most brands don't make them. Here's everything you need to know about RV mattress sizes, how to measure, and where to buy.
RV mattress dimensions are not standardizedacross manufacturers. Two "RV Short Queen" spaces may have different dimensions. Some platforms have curved corners or walkthrough cutouts. Measure your sleeping platform directly — not your old mattress.
| Name | Dimensions | Notes |
|---|---|---|
| RV Short Queen | 60" × 74" | Most common RV master bedroom size. 6 inches shorter than a standard queen. |
| RV King (RV-King) | 72" × 80" | Wider but may be shorter than a standard King. Verify your exact measurements — RV King dimensions vary by manufacturer. |
| RV Short King | 72" × 75" | Common in larger Class A motorhomes. Width like a Cal King but shorter. |
| RV Bunk | 28" × 75" or 28" × 80" | Standard bunk size in most Class C and Class A bunk RVs. |
| RV Full (RV-Full) | 54" × 74" | Similar to a standard Full but 1 inch shorter. Used in some entry-level travel trailers. |
| RV Twin (Bunk Short) | 28" × 70" or 34" × 75" | Varies significantly by manufacturer. Always measure before purchasing. |
| Custom / Odd Shapes | Varies | Corner-radius, curved front, or walkthrough cutouts require custom ordering. See My Green Mattress or RVMattress.com for custom options. |
Most RV sleeping platforms have under-bed storage drawers or height constraints. Measure overhead clearance before choosing mattress thickness.
Memory foam and latex mattresses ship compressed in boxes that fit through standard RV doors. Traditional innerspring mattresses are impractical for most RV installations.
Look for brands that offer RV-specific sizes (Short Queen, RV Bunk, etc.) or custom sizing for unusual platform shapes.
RV mattresses should meet the FMVSS 302 flammability standard (vehicle flammability, different from residential 16 CFR Part 1633). Most RV-specific mattresses comply.
RV use involves movement, vibration, and varying humidity. Look for materials that resist moisture absorption. Memory foam is generally fine; avoid innerspring in humid climates.
RV gross vehicle weight ratings (GVWR) matter — a heavy mattress affects your payload. Low-profile foam mattresses are typically 30–50 lbs vs. 80–100 lbs for a hybrid.
The easiest source for budget RV mattresses. Lucid and Zinus both offer RV Short Queen sizes. Quality is functional at a low price point — good for seasonal or backup RV use.
Family-owned brand in Joliet, IL offering certified organic mattresses in custom sizes. Ideal for RV owners who want organic materials without the chemical exposure of standard foam. Can cut to exact dimensions including curved corners.
Both brands offer natural latex mattresses that can be ordered in non-standard sizes. Latex is ideal for RV use — naturally resistant to dust mites, antimicrobial, and more resistant to humidity than polyurethane foam.
Specialty RV mattress retailers stock the full range of RV sizes and custom cutting. Search "RV mattress [your size]" — several e-commerce sites specialize in this niche with better size selection than general mattress brands.
These brands offer either RV-specific sizes, custom cutting, or non-standard size options that work for RV applications.
The quintessential starter mattress — Linenspa's entry-level bonnell coil hybrid with a thin memory foam layer, widely available at major retailers for under $250 queen.
Lucid's mid-size budget memory foam with bamboo charcoal and gel infusion — widely available at major retailers and a strong value pick in the under-$350 queen segment.
The best-selling ultra-budget memory foam mattress on Amazon, popular for guest rooms, first apartments, and children's rooms.
Avocado's entry-level organic mattress — GOTS-certified organic cotton cover with GREENGUARD Gold certified foam layers. Avocado's most accessible price point.
My Green Mattress Pure Echo — GOLS certified Dunlop latex over GOTS organic cotton coils and wool. Four organic certifications at an accessible organic-tier price.
PlushBeds' entry-level hybrid with gel memory foam comfort layers and a pocketed coil support system. More breathable than the all-latex lineup at a lower price.
Most RV master bedrooms use an RV Short Queen (60×74 inches) — 6 inches shorter than a standard queen. Class C and A bunkhouse RVs typically use RV Bunk size (28×75 inches or similar). Always measure your existing mattress before ordering — RV dimensions are not standardized across manufacturers.
Only if your RV has a slide-out with a full-standard-size sleeping area, which some Class A motorhomes do. Most RV sleeping areas are built to non-standard dimensions. A standard queen (60×80 inches) is 6 inches too long for most RV short queen spaces and won't fit.
Memory foam or latex mattresses in compressed/rolled form are ideal for RVs: they ship in manageable boxes and can be maneuvered through RV doors and into the sleeping area. Traditional innerspring mattresses are nearly impossible to install in most RV sleeping spaces. Low-profile mattresses (6–10 inches) are often necessary due to RV storage drawers underneath.
Most RV sleeping platforms have under-bed storage drawers that limit mattress height. Measure from the sleeping platform to any overhead obstruction (a bunk above, a cabinet, or the ceiling). Most RV mattresses are 6–10 inches thick. Compressed memory foam in this range is the most practical option.
Several brands specialize in RV and non-standard sizes: My Green Mattress (custom sizes, organic), Lucid (available in RV queen), Zinus (affordable RV options on Amazon), and RVMattress.com (RV-specialist with all standard RV sizes). Latex mattresses can also be custom-ordered from several natural mattress brands.
RV mattresses must comply with the FMVSS 302 standard (Federal Motor Vehicle Safety Standard for flammability), which is different from the 16 CFR Part 1633 standard for residential mattresses. Most mattresses sold specifically for RV use comply with FMVSS 302. Organic wool fire barriers typically meet both standards.
Remove your existing mattress and measure the sleeping platform from end to end and side to side — not the old mattress (which may have already been cut incorrectly). Note any cutouts, curved corners, or walkthrough notches. Provide these exact measurements when ordering a custom RV mattress.
A 6-inch foam mattress is the minimum for adult primary sleeping comfort. 8-inch options in quality memory foam or latex are significantly more comfortable and are recommended if your RV platform allows the height. Below 6 inches, most adults will feel the platform through the mattress.
