by RV mattresses are one of the most overlooked upgrades in the RV world — and one of the highest-impact ones. The factory mattress in most RVs is a 4–5 inch foam pad designed to a minimum spec and budget. Replacing it with a quality mattress in the right size transforms sleep quality on the road.
The challenge: RV mattress sizes are non-standard. A residential queen (60x80") won't fit where an RV short queen goes. Getting the dimensions right is step one.
RV Mattress Size Guide
| RV Mattress Type | Dimensions | Common In |
|---|---|---|
| Short Queen | 60" x 75" | Most Class A, B+, C RVs |
| RV King | 72" x 80" | Large Class A motorhomes |
| RV Full (Three-Quarter) | 48" x 75" | Slide-out beds, fifth wheels |
| RV Twin / Bunk | 28" x 75" or 34" x 75" | Bunk beds, rear bedrooms |
| Standard Queen | 60" x 80" | Some large 5th wheels |
| Cab-Over | Variable (measure carefully) | Class C over-cab sleeping area |
Before ordering: Measure your existing mattress — width, length, and depth. Many RV beds have tight clearance on depth. A 12" residential mattress won't fit in a slide designed for an 8" factory mattress. Most RV mattress swaps work well with 8–10" thickness.
What to Look for in an RV Mattress
- Size accuracy: Non-standard sizes mean custom orders. Verify the brand offers your exact dimensions.
- Weight: RV weight limits matter. Memory foam is generally lighter than hybrid. A queen hybrid can weigh 80–100 lbs — factor in slide weight ratings.
- Off-gassing: In enclosed spaces, off-gassing from new foam is more noticeable. Look for CertiPUR-US certified foam.
- Moisture resistance: RVs experience humidity fluctuations. Mattresses with antimicrobial covers or natural latex resist mold better.
- Flexibility: Murphy beds and fold-out configurations need a mattress that flexes without damage. Latex and thinner foam mattresses work better than rigid hybrid constructions.

Top Picks Reviewed
Best Overall: Saatva Classic (Short Queen)
If you're living in your RV part-time or spending extended periods on the road, the Saatva Classic is the closest thing to residential sleep quality in an RV-sized format. Dual coil construction provides the support that foam-only RV mattresses can't replicate. The organic cotton cover resists moisture better than synthetic covers. The 365-night trial is unusually generous for a premium mattress. The main consideration: at 10–14" depending on configuration, confirm your RV bed clearance before ordering.
Best Natural Option: Brentwood Home Cedar
An excellent choice for those prioritizing natural materials. The Cedar uses a natural latex comfort layer over individually wrapped coils. Natural latex is inherently antimicrobial and dust-mite resistant — both meaningful advantages in an RV's more variable environment. Available in most RV sizes. The latex surface runs slightly warm, so pair it with breathable bedding in summer months.
Best Budget: Zinus Green Tea Memory Foam
For weekend warriors and seasonal RV users, the Zinus Green Tea is a dramatic upgrade from factory mattresses at a fraction of the cost. CertiPUR-US certified foam, available in 8" and 10" heights. The "green tea" infusion is largely marketing — but the foam itself is solid for the price. Expect 4–6 years of reasonable use. Not for full-time RVers.
Best for Back Support: Tuft & Needle Original
T&N's proprietary Adaptive Foam is engineered to provide support without the heat trap of traditional memory foam. The Short Queen version is specifically produced for RV fitment. Lighter than most hybrids at ~60 lbs. A strong choice for back sleepers who need firm, flat support without coils.
Saatva Classic — 365-Night Trial
Test it for a full year. White-glove delivery includes old mattress removal. Three firmness levels (Plush Soft, Luxury Firm, Firm). Available in Short Queen for RV fitment.
Frequently Asked Questions
What size mattress fits a standard RV queen bed?
Most RVs use a Short Queen: 60 inches wide by 75 inches long — 5 inches shorter than a residential queen (60x80"). Always measure your existing mattress before ordering. Some newer fifth wheels and Class A motorhomes fit a standard residential queen (60x80"). Do not assume — the 5-inch difference matters for fitment.
Can I use a regular mattress in my RV?
Only if the dimensions match. A residential queen (60x80") physically won't fit in a Short Queen space. However, if your RV has a standard queen-sized platform (some larger fifth wheels do), a regular mattress will work fine. The other consideration is weight — confirm your slide or bed platform can handle the load of a heavier residential mattress.
How thick should an RV mattress be?
8–10 inches is the sweet spot for most RV applications. Factory mattresses are typically 4–6 inches. Going above 12 inches can create clearance problems with overhead storage, Murphy bed mechanisms, or slide-room height limits. Measure the available depth from the platform surface to any overhead obstruction before ordering.
What's the best mattress for a Class B van conversion?
Van conversions often use custom dimensions. For fixed rear beds, a 54x80" or 48x75" foam mattress (cut to fit if needed) is common. Memory foam works well in vans because it can flex to fit irregular shapes and is lighter than hybrids. Natural latex is another van-friendly option for its antimicrobial properties. For custom-cut mattresses, Foam Factory and Foam Order are specialized suppliers.
How do I prevent moisture and mold in an RV mattress?
Use a waterproof mattress protector, allow ventilation between the mattress and platform (slatted platforms or Bunkie boards with gaps are better than solid plywood), run the RV's dehumidifier or AC when parked in humid conditions, and lift the mattress to air out when the RV isn't in use. Latex mattresses are the most mold-resistant material choice for RV use.
