Quick Answer: Replace your RV mattress with a foam or hybrid model in your exact RV size, since RV bunks rarely match standard residential dimensions. Measure carefully, account for narrow door and corner clearances during install, and add a moisture barrier underneath to prevent condensation against the metal floor.
If you have ever spent a night in a travel trailer, fifth wheel, or camper and woken up with a sore back, you are not imagining things. Factory-installed RV mattresses are one of the most universally criticized components of recreational vehicles, and for good reason. RV manufacturers prioritize weight reduction and cost savings over comfort, which means the mattress that came with your unit is almost certainly the weakest link in your sleep setup.
The good news: replacing an RV mattress is one of the simplest and most impactful upgrades you can make. This guide covers every RV mattress size sold in Canada, how to measure properly, which materials work best in the RV environment, and how to navigate the challenge of getting a full-size mattress through a narrow RV door.
Why Factory RV Mattresses Are So Bad
Understanding why the factory mattress fails helps you choose a better replacement:
- Low-density foam. Most factory RV mattresses use polyurethane foam with a density of 1.2 to 1.5 lb/ft3. For comparison, a quality home mattress uses foam at 1.8 to 2.5 lb/ft3 or higher. Low-density foam compresses within months, creating body impressions and reducing support.
- Thin construction. Factory mattresses are typically 6 to 8 inches thick to save weight and keep the bed height compatible with low RV ceiling clearances. While thickness alone does not determine comfort, thin mattresses have less room for comfort layers above the support core.
- Weight constraints. Every pound matters in a towable RV because it affects fuel economy and towing capacity. A quality queen mattress weighs 50 to 80 lbs, while a factory RV short queen may weigh only 25 to 35 lbs. That weight savings comes directly from reduced material quality.
- Cost pressure. RV manufacturers build to a total price point. The mattress is one of the easiest places to cut costs because buyers are focused on the kitchen, bathroom, and slide-out features during the purchase decision.
On RV forums across Canada, the most common advice for new RV owners is: "Replace the mattress before your first trip." It is that universal. A Reddit user in r/RVLiving summed it up: the factory mattress is a placeholder, not a sleeping surface. Spending $400 to $1,000 on a quality replacement transforms the RV sleeping experience and pays for itself in better rest across hundreds of camping nights.

Complete RV Mattress Size Chart
RV mattresses use different dimensions than standard home mattresses. The most common difference is length: many RV sizes are 5 to 6 inches shorter than their residential equivalents to accommodate the compact floor plans of travel trailers and fifth wheels.
| RV Size | Dimensions (inches) | Standard Equivalent | Common In |
|---|---|---|---|
| RV Bunk (Small) | 28" x 75" | Narrower than twin | Bunkhouse trailers, kids' sleeping areas |
| RV Twin | 38" x 75" | Standard twin (38" x 75") | Bunks, dinette conversions |
| RV Three-Quarter | 48" x 75" | Between twin and full | Smaller campers, truck campers |
| RV Full / Double | 53" x 75" | Narrower, shorter than standard full | Pop-up campers, small trailers |
| RV Short Queen | 60" x 75" | 5" shorter than standard queen | Most travel trailers, most popular RV size |
| RV Queen | 60" x 80" | Same as standard queen | Larger fifth wheels, Class A motorhomes |
| RV Narrow King | 72" x 80" | 4" narrower than standard king | Premium fifth wheels |
| RV King | 76" x 80" | Same as standard king | Large Class A, luxury fifth wheels |
| RV Short King | 72" x 75" | Narrower and shorter than standard king | Mid-range fifth wheels |
| RV Olympic Queen | 66" x 80" | 6" wider than standard queen | Some luxury trailers |
| RV California King | 72" x 84" | Same as residential Cal King | Luxury Class A motorhomes |
The Short Queen dominates. If you are shopping for an RV mattress replacement in Canada, there is a strong chance you need a Short Queen (60" x 75"). This size fits the majority of travel trailers sold at Canadian dealerships, including models from Jayco, Keystone, Forest River, Coachmen, and Grand Design.
How to Measure Your RV Bed Platform
Never assume your RV mattress matches a standard size. Always measure the bed platform directly, not the old mattress (which may have compressed unevenly over time).
Step 1: Remove the old mattress completely and set it aside.
Step 2: Measure the width of the bed platform at both ends. RV platforms are not always perfectly rectangular. Some have rounded corners or angled edges at the foot end to accommodate slide-out mechanisms or wall curves.
Step 3: Measure the length from headboard wall to footboard edge on both the left and right sides.
Step 4: Measure the height from the platform to the ceiling or to any overhead cabinets. This determines the maximum mattress thickness you can use while still sitting comfortably in bed.
Step 5: Photograph the platform from above, noting any rounded corners, cutouts, or non-rectangular shapes. If the platform is not a standard rectangle, you will need a custom-cut mattress.
Step 6: Measure the narrowest doorway between the RV entrance and the bedroom. This determines whether a full-size mattress can physically get to the bed.
Mattress Types for RVs: Foam vs Hybrid vs Latex
The RV environment has specific requirements that make some mattress types better suited than others:
| Type | Pros for RV Use | Cons for RV Use | Weight (Short Queen) |
|---|---|---|---|
| Memory Foam | Compresses for shipping (bed-in-a-box), excellent motion isolation, no squeaking on RV platforms | Can sleep warm, off-gasses (air out before first use in sealed RV), heavier than low-density factory foam | 40 to 55 lbs |
| Latex Foam | Naturally antimicrobial and mould-resistant (excellent for humid RV environments), breathes better than memory foam, very durable | Heavier, more expensive, less compression for shipping | 55 to 70 lbs |
| Hybrid (Foam + Coils) | Best all-around comfort, good airflow through coil layer, closer to home-bed feel | Heaviest option, harder to compress for narrow doors, coils may squeak on plywood platforms | 60 to 80 lbs |
| Gel Memory Foam | Cooler than traditional memory foam, same shipping advantages | Gel effect diminishes over time in some cheaper brands | 40 to 55 lbs |
For most Canadian RV owners, a medium-firm all-foam or gel memory foam mattress in the 8 to 10 inch range hits the sweet spot between comfort, weight, and practicality. Foam mattresses compress into a box for easy transport through narrow RV doors, do not squeak on plywood platforms, and provide a dramatic upgrade over factory foam.
Choosing the Right Thickness
RV ceiling height and cabinet clearance limit your mattress thickness. Here is how to decide:
| Thickness | Best For | Comfort Level |
|---|---|---|
| 6 inches | Bunk beds, dinette conversions, low-clearance areas | Basic. Suitable for occasional use or children. |
| 8 inches | Most travel trailers, truck campers | Good. Adequate for regular weekend camping. |
| 10 inches | Fifth wheels, larger trailers with adequate ceiling height | Excellent. Closest to home-bed comfort. The most popular replacement thickness. |
| 12 inches | Luxury fifth wheels, Class A motorhomes with residential-height ceilings | Premium. Full residential-grade comfort. |
The ceiling test: Sit upright on your current bed platform (without the mattress) and measure from the top of your head to the ceiling or overhead cabinets. Subtract your desired mattress thickness. You should have at least 24 inches of clearance above the mattress surface to sit up comfortably.
Getting the Mattress Into Your RV
This is the challenge that catches many first-time RV mattress buyers off guard. RV entry doors typically measure 26 to 30 inches wide, and the hallway from the door to the bedroom often includes a 90-degree turn past the bathroom.
Three Approaches
1. Bed-in-a-box (best option). Compressed foam and gel foam mattresses are vacuum-sealed and rolled into a box that measures roughly 20" x 20" x 42" for a Short Queen. This fits through any RV door. Once in the bedroom, you cut the plastic wrapping and the mattress expands to full size over 24 to 72 hours. Open windows during expansion to ventilate off-gassing.
2. Fold and carry. All-foam mattresses (even those not shipped compressed) can be bent and folded temporarily for transport through tight spaces. Wrap the mattress in a fitted sheet to keep it together, fold in half lengthwise, and maneuver through the doorway. This does not damage foam.
3. Remove a window or wall panel. For hybrid mattresses with coils that cannot be folded, some RV owners remove a bedroom window panel to slide the mattress in from outside. This is more involved but avoids the door constraint entirely. Check your RV manual before attempting this.
Moisture, Mould, and Ventilation
RV mattresses face a moisture challenge that home mattresses do not. RVs are sealed environments with limited ventilation, and Canadians often camp in humid conditions (lakeside campgrounds, early spring, fall shoulder season). When you sleep, your body releases moisture through perspiration. In a home, this moisture dissipates through the mattress and into the bedroom air. In an RV, it can become trapped between the mattress bottom and the plywood platform, creating a mould risk.
Prevention Strategies
- Ventilation pad. Place a breathable mesh ventilation pad (like the HyperVent or similar product) between the mattress and the platform. This creates a small air gap that allows moisture to escape. Cost: $60 to $120 CAD.
- Moisture barrier. Use a waterproof but breathable mattress protector on the sleeping surface. This prevents sweat from soaking into the mattress core.
- Air circulation. When not using the RV, prop the mattress on its side or fold back the bedding to allow air circulation around the platform. Open a roof vent when sleeping to reduce humidity buildup.
- Choose latex. Natural latex is inherently antimicrobial and mould-resistant, making it the best material choice for humid RV environments. It is more expensive but dramatically reduces mould risk.
If you camp in Ontario's cottage country, the Maritimes, or British Columbia's coast, humidity is a real concern. If you camp primarily in the drier Prairie provinces or during peak summer, moisture management is less critical but still worth addressing. A $80 ventilation pad is cheap insurance against a $500+ mattress replacement.
Canadian RV Mattress Options
Several mattress companies offer RV-specific sizes that ship to Canadian addresses:
| Brand | RV Sizes Available | Type | Price Range (CAD) | Ships From |
|---|---|---|---|---|
| Silk and Snow | Short Queen | Memory foam | $625 to $750 | Canada |
| Juno | RV Bunk Small, Three-Quarter, Short Queen | Memory foam | $400 to $700 | Canada |
| GhostBed | Short Queen, RV Queen, RV King | Memory foam | $700 to $1,000 | Ships to Canada |
| Brooklyn Bedding Aurora Luxe | Short Queen, RV King, RV Bunk | Hybrid | $900 to $1,400 | Ships to Canada |
| Lippert Thomas Payne | All standard RV sizes | Gel memory foam | $500 to $800 | RV dealer network |
Important note about cross-border shipping: Some US mattress brands will ship to Canada but charge significant shipping fees ($100 to $300+) and you may be responsible for duties and taxes at the border. Canadian brands like Silk and Snow and Juno include shipping in their prices and handle all taxes, making the total cost more predictable.
Custom Cut and Odd-Shape Solutions
If your RV bed platform has rounded corners, an angled foot end, or unusual dimensions that do not match any standard size, you have two options:
Option 1: Order Custom
Several Canadian mattress manufacturers offer custom-cut services. You provide a template (most accept a paper or cardboard tracing of your platform shape) and they cut the mattress to match. Custom cuts typically add $100 to $200 to the mattress price and extend delivery by 1 to 2 weeks.
Option 2: DIY Trim
All-foam mattresses (memory foam, latex, polyfoam) can be cut at home with a long serrated knife (a bread knife works well) or an electric carving knife. This is a common practice among RV owners and does not void most warranties as long as you are trimming to fit, not structurally altering the mattress.
How to trim a foam mattress:
- Remove the mattress cover (if removable)
- Mark your cut line with masking tape or a marker
- Use a long serrated knife, cutting in slow, steady strokes
- Cut from one side, then flip and match the line from the other side for thick mattresses
- Use scissors to trim the cover to match, then re-zip or fold under
Note: Hybrid mattresses with coils cannot be trimmed at home. If you have a non-standard bed shape and want a hybrid, you must order custom.

Frequently Asked Questions
Only if your RV bed platform measures 60" x 80" (a standard queen). Most travel trailers use a Short Queen platform (60" x 75"), which is 5 inches shorter. A standard queen mattress will overhang by 5 inches at the foot, interfering with slide-out mechanisms or blocking walkways. Always measure your platform before ordering.
The easiest method is to order a bed-in-a-box style mattress (compressed and rolled). The box typically measures about 20" x 20" x 42" for a Short Queen, which fits through any RV door. All-foam mattresses can also be folded in half for transport. Hybrid mattresses with coils are harder to maneuver and may require window removal in some RV layouts.
For most travel trailers, 8 to 10 inches is ideal. Measure from the bed platform to the ceiling or overhead cabinets while sitting upright, and ensure you have at least 24 inches of clearance above the mattress surface. Bunk beds and dinette conversions may be limited to 6 inches due to lower ceilings.
Yes, and it is arguably more important in an RV than at home. RVs have limited ventilation, and moisture from body heat can become trapped between the mattress and the plywood platform, causing mould. Use both a waterproof mattress protector on top and a ventilation pad (mesh layer) underneath the mattress to promote airflow.
Yes. All-foam and latex mattresses can be trimmed with a long serrated knife or electric carving knife. This is a common practice among RV owners. Order a mattress slightly larger than your platform and trim to fit. Hybrid mattresses with coils cannot be cut at home and must be ordered in the correct size or custom-made.
