Quick Answer: For most van builds, the best van life mattress in Canada is the HEST Dually Custom S (around $500 to $700 CAD), a 4-inch memory foam mattress with curved rear corners that fit Sprinter, Transit, and Promaster door openings without cutting. Ontario builders wanting an exact custom fit can have Foamite cut foam factory-direct.
The best van life mattress for most builds is the HEST Dually Custom S (~$500-$700 CAD), a memory foam mattress designed specifically for camper vans with curved corners to fit Sprinter, Transit, and Promaster cargo areas. For a budget option, buy a Zinus or Amazon Basics memory foam mattress ($200-$350) and cut it to your platform dimensions with an electric carving knife. For a premium all-in-one solution, Foamite (Ontario) manufactures custom van mattresses in 45 foam grades at factory-direct pricing.
In This Guide
Van life in Canada comes with a unique mattress challenge: your sleeping platform is custom-built, your space is extremely limited, and your mattress needs to handle everything from -20°C winter camping in British Columbia to humid Ontario summers. Factory RV mattresses are designed for standard beds. Van life mattresses need to fit custom platforms, fold for storage, and survive daily use.
Van Life Mattress vs. RV Mattress: Different Needs
If you are building a Sprinter, Transit, or Promaster conversion, your mattress requirements differ from a factory RV in several key ways:
| Factor | Factory RV | Van Conversion |
|---|---|---|
| Bed size | Usually standard (Queen, Full, RV Short Queen) | Custom width/length based on build |
| Headroom | 6-7 feet ceiling | Often 3-4 feet above platform |
| Storage | Fixed bed, stays in place | May fold or store to create living space |
| Platform shape | Rectangular | Curved corners, wheel well cutouts |
| Climate control | Furnace + AC | Diesel heater, minimal AC, more temp swings |
| Budget | $300-$800 replacement | $150-$700 custom |
Mattress Sizing for Popular Van Builds
The most important measurement is your sleeping platform, not the van model. But here are common platform sizes for popular Canadian van conversions:
Mercedes Sprinter (144" and 170" wheelbase)
Platform width: 52-56 inches (widest at wheel wells). Length: 72-78 inches (depending on where the bed ends and kitchen begins). With rear doors, the back corners need to be cut at approximately 45 degrees to clear door hinges. Most Sprinter builds use a mattress that is 54" x 75" with two angled back corners.
Ford Transit (148" and 148" extended)
Platform width: 54-58 inches. Length: 72-80 inches. The Transit cargo area is slightly wider than the Sprinter, giving more mattress real estate. Rear door clearance is similar and usually requires angled corners on the back edge.
Ram Promaster (136" and 159")
Platform width: 60-64 inches (the widest of the three). Length: 70-78 inches. The Promaster's front-wheel-drive design eliminates rear wheel wells, giving you a flat, wide cargo floor. This makes mattress fitting easier. However, some builds have the bed running widthwise (east-west) rather than lengthwise.
Comfort Tip
Always measure your finished platform, not the van specs. Insulation, wall panels, cabinetry, and electrical runs all reduce your usable sleeping area by 2-6 inches in each direction. Build your platform first, then measure for the mattress. Ordering a mattress based on factory van dimensions guarantees it will not fit.
5 Best Van Life Mattress Options in Canada
1. HEST Dually Custom S (Best Pre-Made Van Mattress)
- Price: ~$500-$700 CAD (~$399-$549 USD + shipping)
- Thickness: 4 inches
- Material: Enhanced memory foam, waterproof bottom
- Sizes: S60 (60" wide) and S75 (75" wide) with curved rear corners
- Fold: Horizontal bi-fold for daytime storage
- Available at: hest.com (ships to Canada), Amazon.ca
The HEST Dually Custom S is the only major mattress designed specifically for camper vans. The curved rear corners fit between rear door openings on Sprinter, Transit, and Promaster builds without custom cutting. The horizontal bi-fold design lets you fold the mattress in half to create a seating area or access under-bed storage during the day.
The memory foam is the same enhanced formula used in HEST's camping line, with an R-value of 8.8. This means excellent insulation from cold platforms during Canadian winter van camping. The waterproof bottom protects against condensation from the platform underneath.
Best for: Van lifers who want a purpose-built solution without DIY cutting.
2. Foamite Custom Van Mattress (Best Canadian Custom)
- Price: ~$200-$600 CAD (factory-direct)
- Thickness: Custom (4-8 inches)
- Material: 45 foam grades including HD foam, memory foam, latex, Qik-Dri
- Process: Pattern your platform, bring/send template, custom-cut mattress
- Location: Ontario factory (pickup available)
- Website: foamite.com
Foamite is a foam manufacturer in Ontario that specializes in custom-cut mattresses for vans, boats, and RVs. Because they manufacture the foam on-site, you get factory-direct pricing without retail markup. With 45 foam grades available, you can build a layered mattress: firm base for support, soft top for comfort, with the exact density and feel you prefer.
The process is hands-on: create a cardboard or newspaper template of your sleeping platform, bring it to the factory (or mail it), and they cut your mattress to the exact shape. For Ontario-based van builders, factory pickup eliminates shipping costs entirely.
Best for: Ontario van builders who want precise custom sizing at factory-direct pricing.
3. DIY Cut Memory Foam (Best Budget Option)
- Price: $150-$350 CAD
- Thickness: 6-10 inches (cut to preference)
- Material: Memory foam or gel memory foam
- Best products: Zinus Green Tea ($200-$350), Amazon Basics ($250-$400), Lucid ($250-$350)
- Available at: Amazon.ca, Costco.ca
The most popular approach among Canadian van lifers: buy a cheap memory foam mattress from Amazon.ca and cut it to fit. An electric carving knife (the kind used for turkey) produces clean, straight cuts through memory foam. Most van lifers buy a Full or Queen size and trim to their platform dimensions.
The Zinus Green Tea is the most common choice because of its low price, CertiPUR-US certification, and availability in multiple thicknesses. For a 6-inch version, expect to pay around $200 CAD. Many van lifers cut the 10-inch version down to 6 inches (removing the firm base layer) to save headroom while keeping the memory foam comfort layer.
Best for: Budget-conscious van builders who are comfortable with DIY cutting.
4. Sailrite Foam (Best for DIY Quality)
- Price: ~$300-$600 CAD (~$200-$450 USD + shipping)
- Thickness: Custom layered (typically 3-5 inch combinations)
- Material: High-density marine and recreational foam, various densities
- Available at: sailrite.com (ships to Canada)
Sailrite specializes in marine and recreational vehicle foam that is designed for environments with temperature swings and moisture. Their foam is denser and more durable than consumer mattress foam, which matters when you are sleeping on the same mattress every night for years.
The layered approach is popular: order a 1-inch firm base, 2 inches of medium support, and 1 inch of soft topper. Sailrite ships the layers separately, and you stack and bond them yourself. This gives you precise control over firmness and feel. Covers are sold separately or you can have a local upholstery shop sew a custom cover.
Best for: Full-time van lifers who want marine-grade durability and custom firmness layering.
5. Tri-Fold Foam Mattress (Best for Convertible Layouts)
- Price: $80-$200 CAD
- Thickness: 4-6 inches
- Material: CertiPUR-US foam or memory foam
- Best products: Milliard Tri-Fold (~$100-$170), Lucid Tri-Fold (~$120-$200)
- Available at: Amazon.ca
Tri-fold mattresses work well in vans where the bed converts to a seating area. The three panels fold into a compact block that can be stored upright or used as a backrest. The Milliard 6-inch Tri-Fold is the most popular choice on Amazon.ca and fits many van builds in the Full size (54 x 75 inches) without any cutting needed.
The trade-off is that tri-fold mattresses have seams between panels, which you can feel when lying across the fold lines. Sleeping lengthwise (head at one end, feet at the other) positions the seams under your knees and upper thighs, where they are less noticeable. Sleeping widthwise puts a seam right under your back.
Best for: Weekend van campers with convertible layouts who need the bed to become a couch or workstation.

How Thick Should a Van Mattress Be?
Sleep Science
Research on mattress surface pressure (Defloor, 2000, Journal of Clinical Nursing) found that side sleepers need a minimum of 3 inches of conforming material to adequately relieve pressure at the shoulder and hip. Below 3 inches, pressure concentration increases significantly, leading to discomfort, tossing, and disrupted sleep. For back sleepers, 2 inches of comfort foam on a firm base is sufficient.
4 inches: The sweet spot for most van builds. Provides adequate side-sleeper comfort while preserving headroom. With a raised platform (30-36 inches off the floor), 4 inches of mattress still gives you 30-40 inches of sitting clearance in a high-roof Sprinter (72-inch interior height).
6 inches: Maximum comfort, minimum headroom. Only practical if your platform is 24 inches or lower, or in a high-roof van with generous ceiling height. The extra 2 inches makes a noticeable comfort difference for daily sleeping but reduces sitting clearance.
3 inches: Minimum for occasional use. Fine for weekend camping, but full-time van lifers will develop pressure point pain within weeks. If headroom forces you to 3 inches, use high-density foam (2+ lb/ft3) rather than low-density foam that will bottom out.
Moisture Management in a Van
Condensation is the number one enemy of van mattresses. When you sleep, your body releases 200-400 mL of moisture per night through breathing and perspiration. In a sealed van, this moisture condenses on cold surfaces, including the bottom of your mattress and the metal platform underneath.
Ventilation gap. Place a Hypervent mesh ($50-$80 on Amazon.ca) or wooden slats (1-2 cm spacing) between your mattress and the platform. This creates airflow that prevents moisture from pooling. Some van builders use perforated plywood platforms to achieve the same effect.
Breathable foam. Avoid solid memory foam on the bottom layer. Memory foam is closed-cell and traps moisture. Use open-cell polyurethane, latex, or Qik-Dri marine foam as the base layer to allow moisture to pass through rather than accumulate.
Daily routine. Open windows or a fan vent for 15-30 minutes each morning to flush humid air. Lift or fold your mattress when possible to let the underside dry. In winter, a small dehumidifier (the Eva-Dry or similar rechargeable units) helps manage cabin humidity without draining your battery bank.
DIY: Cut Your Own Van Mattress
Tools needed: Electric carving knife (preferred), bread knife (backup), marker, tape measure, and cardboard or newspaper for templating.
Step 1: Build your sleeping platform first. Finish all insulation, panels, and cabinetry before measuring.
Step 2: Create a cardboard template of your platform. Include wheel well cutouts, curved corners, and any notches for door clearance.
Step 3: Remove the mattress cover. Unzip and slide the foam out of the cover.
Step 4: Place the template on the foam, trace with a marker, and cut with the electric carving knife. Long, smooth strokes produce cleaner edges than short, choppy cuts.
Step 5: If needed, reduce thickness by cutting horizontally through the foam. Mark the desired thickness on all four edges, then cut from one side to the other in a single horizontal pass.
Step 6: Replace the cover (tucking excess) or have a local upholstery shop sew a custom cover for $50-$100.
Frequently Asked Questions
Can I use a regular mattress in my van?
If your van build has a standard-size platform (Full, Queen), a regular bed-in-a-box mattress works. Douglas ($799), Juno ($499), and Endy ($895) all compress enough for tight van doorways. However, regular mattresses are 10-12 inches thick, which may reduce headroom significantly. Most van lifers prefer 4-6 inch mattresses for this reason.
How do I keep my van mattress from getting mouldy?
Three essentials: (1) ventilation gap between mattress and platform (Hypervent mesh or slats), (2) daily airing for 15-30 minutes with windows open, and (3) a breathable base layer (not solid memory foam). If you follow these three practices, mould is preventable even in humid Canadian summers.
What is the best mattress for a Sprinter van?
The HEST Dually Custom S is designed with curved corners to fit Sprinter rear door openings. For a custom fit, Foamite or a local foam supplier can cut a mattress to your exact platform dimensions. The typical Sprinter sleeping platform is 54 x 75 inches with two angled rear corners.
Is memory foam or latex better for van life?
Latex is more breathable, durable, and moisture-resistant, making it technically better for the van environment. However, latex is heavier and more expensive. Memory foam is lighter, cheaper, and more comfortable for most people, but it retains heat and moisture. For full-time van life (12+ months), invest in latex or at minimum a latex top layer. For weekend/seasonal use, memory foam is fine with proper ventilation.
How much does a custom van mattress cost in Canada?
Foamite (Ontario) charges $200-$600 depending on foam type, thickness, and complexity. HEST's pre-made Dually Custom S is $500-$700 CAD. Sailrite foam shipped to Canada runs $300-$600. DIY cut mattresses cost $150-$350. For a permanent van conversion where the mattress stays in place, budget $300-$500 for a quality solution that will last 5+ years.
Should I get a folding or solid van mattress?
Depends on your layout. If your bed doubles as a seating area or work space, a bi-fold or tri-fold mattress is essential. If you have a permanent fixed bed (common in longer Sprinter builds), a solid non-folding mattress provides better comfort because there are no seam lines to feel. The HEST Dually Custom S offers a bi-fold compromise that stores well without seam discomfort.
