Quick Answer: The three essential RV mattress accessories are a waterproof protector (RV environments are humid), a fitted cover or encasement for storage and transport, and short queen sheets (60" x 75", not standard queen 60" x 80"). Skipping the protector in an RV is a common mistake that leads to mould and premature mattress failure.

RV Mattress Protector: Why It Is Non-Negotiable
Residential mattresses benefit from a protector. RV mattresses require one. The difference is the environment. A home bedroom maintains relatively stable temperature and humidity. An RV is parked outside, often in conditions that range from cold and damp spring nights to humid Ontario summers to cool autumn evenings. This thermal cycling causes condensation to form on and within the mattress, creating conditions for mould and mildew growth.
Low-density factory RV foam is particularly susceptible because its open pores absorb moisture readily and dry slowly in an enclosed RV bedroom. A waterproof mattress protector creates a barrier that prevents moisture from reaching the foam, dramatically extending mattress lifespan.
What a Good RV Mattress Protector Does
- Moisture barrier: Prevents condensation, spills, and humidity from penetrating the foam
- Allergen barrier: Dust mites accumulate rapidly in an RV mattress without protection. A protector with a tightly woven or waterproof layer significantly reduces dust mite load.
- Stain protection: Food, drink, and sunscreen are common RV mattress contaminants
- Extends mattress life: A protected mattress can last 2-3 additional seasons compared to an unprotected one in an RV environment
Research published in the Journal of Allergy and Clinical Immunology (2003) found that allergen-impermeable mattress covers significantly reduced dust mite allergen levels compared to unprotected mattresses. For RV allergy sufferers, a protector is particularly valuable.
What to look for in an RV mattress protector:
- Waterproof backing (polyurethane or TPU laminate, not just "water-resistant")
- Breathable top surface so the protector does not create a hot or crinkly sleep surface
- Deep pocket fitting: RV mattresses can be irregular in thickness; a protector with 6"-8" side depth fits 5"-6" RV mattresses without bunching
- Machine washable: essential for camping use where regular washing is needed
RV Mattress Cover and Encasement
An RV mattress cover (sometimes called an encasement) differs from a protector: it typically covers all six sides of the mattress, sealing it completely. This is useful for RVs that are stored for winter, where a fully enclosed mattress is less vulnerable to pests, moisture accumulation, and dust during storage.
For RVs stored in Ontario from November through April, a full encasement during the off-season followed by a regular fitted protector during camping season is the most effective combination.
Protector vs Cover vs Encasement
| Product | Coverage | Best For |
|---|---|---|
| Mattress protector (fitted) | Top and sides | Active camping use: protects from moisture, spills, allergens during sleep |
| Mattress encasement (zippered) | All 6 sides | Storage and transport: fully seals mattress against pests and moisture when RV is closed |
| Mattress bag (disposable) | All 6 sides | Moving or long-term storage only; not for sleep use |
For Canadian RVers who store their units over winter, a zippered encasement is a practical investment. Mice and other rodents are an unfortunately common problem in stored RVs across Ontario; a zippered encasement makes the mattress significantly less accessible as nesting material.
Short Queen Sheets: The Most Missed Accessory
This is where many Canadian RVers run into frustration. A short queen RV mattress is 60" x 75", while a standard residential queen is 60" x 80". That 5-inch length difference means standard queen sheets will not fit properly: they will bunch at the foot and pull loose from the head every night.
RV Sheet Size Guide
| RV Mattress Size | Dimensions | Required Sheet Size |
|---|---|---|
| Short queen (most common RV) | 60" x 75" | RV short queen sheets (NOT standard queen) |
| RV queen (some Class A) | 60" x 80" | Standard queen sheets fit |
| RV full | 54" x 75" | RV full sheets or custom |
| RV twin / bunk | 38" x 75" | RV twin or fitted twin with tucked length |
| RV narrow bunk | 28"-34" x 75" | Custom or children's fitted |
RV-specific short queen sheet sets are widely available from RV supply stores and online retailers in Canada. When purchasing, confirm the fitted sheet's pocket depth: a standard 14"-15" pocket fits 5"-6" RV mattresses well. Look for sets that include the fitted sheet, flat sheet, and pillowcases in the 60" x 75" short queen size.
Materials: cotton percale or microfibre are the most common. Microfibre dries faster, which is useful in RV environments where line drying is common. Cotton feels cooler in warm weather camping. Flannel sheet sets are popular for fall camping in Ontario.
RV Mattress Topper Basics
A mattress topper adds a comfort layer on top of the existing RV mattress. For RV use, the most practical toppers are 1"-2" thick: substantial enough to improve feel, thin enough to stay within slide-out clearance limits.
Short queen toppers (60" x 75") are available from most online bedding retailers and some brick-and-mortar stores. Memory foam toppers in 1"-2" thickness are the most common choice, providing pressure relief for side sleepers without adding significant weight.
Dorothy, Sleep Specialist: "Short queen sheets are the thing people always forget until they get to the campsite and realize their sheets do not fit. It is a simple fix but a frustrating one to discover at 10 PM after a long drive. We always remind people when they pick up an RV mattress to confirm their sheet sizes before they head out."

Do I need a special mattress protector for my RV in Canada?
Any waterproof mattress protector with a breathable top surface works in an RV. The key requirement is genuine waterproofing (not just water resistance), deep pocket fitting for RV mattress thickness, and machine washability. Standard residential protectors in the correct size work well.
Where can I buy short queen sheets in Canada?
Short queen (60" x 75") sheet sets are available from RV supply stores, Walmart Canada, Canadian Tire, and online retailers. When purchasing, confirm the fitted sheet pocket depth (14"-15" for most RV mattresses) and that the set is specifically labeled as short queen, not standard queen.
How do I protect my RV mattress during winter storage?
Use a zippered mattress encasement that covers all six sides to protect against moisture accumulation, pests, and dust during Ontario's off-season. Elevate the mattress slightly if possible to allow airflow underneath. Leave a small desiccant (moisture absorber) packet near the mattress in the enclosed RV bedroom.
Will a regular queen topper fit an RV short queen mattress?
A standard queen topper (60" x 80") is 5 inches longer than a short queen RV mattress (60" x 75"). You can use it by folding or trimming the extra 5 inches at the foot. Purpose-made short queen toppers are available and more practical: they fit without modification and stay in place better.
Can I use a queen mattress cover with a zipper in an RV, and what should I look for?
A zippered mattress cover (encasement) works for RV queen mattresses with one important caveat: RV queen mattresses in Canada are commonly 60 by 75 or 60 by 80 inches depending on the RV manufacturer, but some older or non-standard RV platforms use non-standard dimensions like 60 by 72 or 58 by 80 inches. A residential queen zippered encasement (designed for the standard 60 by 80-inch residential queen) may not fit an RV queen mattress if the dimensions differ. Before purchasing a zippered cover for an RV mattress, measure the mattress length (head to foot) and width as well as the mattress depth (thickness) - a residential encasement with a 10-inch depth gusset will not work on an RV mattress that is 6 inches thick, as the excess fabric bunches at the corners and the zipper will not close cleanly. RV-specific zippered mattress encasements are available from specialty RV outfitters and online through Amazon Canada; these are sized for common RV dimensions and typically feature lighter fabric weight (important in RVs where storage space is limited) and moisture-wicking properties for condensation management in RV interiors. The Canadian Chiropractic Association's guidance on sleep surface maintenance recommends protective covers for any mattress that will see variable humidity or temperature conditions - exactly the environment RV mattresses face. Talia says: "Measure twice before ordering any mattress cover for an RV - residential queen and RV queen are not always the same size, and a cover that doesn't fit is completely useless."
