Sleeping in a van sounds romantic until your third night on a thin camping pad with a sore back. The mattress you choose for van life, a sprinter conversion, or a glamping setup makes the difference between a lifestyle you can sustain and one you abandon after a few uncomfortable weeks.
Most van life mattress advice comes from people selling mattresses online. This guide covers what actually matters for sleeping well in a vehicle or semi-permanent outdoor setup, including the moisture and temperature problems nobody warns you about.
Why Van Mattresses Are Different
A van mattress faces challenges that a bedroom mattress never deals with:
- Condensation: Your body releases about 200 to 400 millilitres of moisture per night through perspiration and breathing. In a house, this moisture disperses into the room. In a van, it condenses on the coldest surface, which is usually the metal floor directly under your mattress. This creates mould and mildew problems that can ruin a mattress in weeks
- Non-standard dimensions: No van conversion uses standard mattress sizes. A Mercedes Sprinter 144 wheelbase fits roughly 130 x 185 cm lengthwise. A Ford Transit might be 140 x 178 cm. These dimensions do not match any standard mattress
- Weight matters: Unlike a bedroom mattress that sits in one place for years, a van mattress gets moved, folded, or lifted regularly. Heavy innerspring mattresses are impractical
- Temperature swings: A van interior can range from below freezing in Canadian winters to over 40 degrees Celsius in summer sun. Your mattress needs to handle both extremes
Best Mattress Materials for Van Life
Natural Latex (Best Overall)
Natural latex is the top choice for van and mobile living for several reasons. It is naturally antimicrobial and resistant to mould, which matters enormously in high-moisture environments. It breathes well, preventing the heat trap that memory foam creates. And it comes in thinner profiles (4 to 6 inches) that still provide genuine comfort and support.
The downside is cost. A custom-cut natural latex mattress runs 30 to 50 percent more than foam alternatives. But given that moisture damage can destroy a cheaper mattress in one season, the longevity often justifies the price.
High-Density Polyurethane Foam
A solid option for budget builds. High-density foam (1.8 to 2.5 pounds per cubic foot density) provides decent support in a 4 to 6 inch profile, is lightweight, and can be easily cut to custom dimensions with an electric carving knife. Look for CertiPUR-US certified foam for lower off-gassing, which is especially important in the confined air space of a van.
Memory Foam (Use with Caution)
Memory foam is popular in van conversions because it is affordable and comfortable. However, it has significant drawbacks for mobile use. It traps heat, making summer sleeping uncomfortable without air conditioning. It absorbs and holds moisture, accelerating mould growth. And it becomes noticeably firmer in cold temperatures, so winter sleeping in an unheated van can feel like sleeping on a board.
If you use memory foam, pair it with a proper ventilation system underneath and a moisture-barrier cover.
When warm body heat passes through your mattress and meets the cold van floor or platform, water vapour condenses into liquid. This is the same process that creates dew on grass. In a van, this trapped moisture has nowhere to evaporate, and within days it creates a perfect environment for mould growth. This is why mattress base ventilation is not optional in van builds; it is essential.
Sprinter Van Mattress Sizing
The three most common van conversion platforms each have different sleeping area constraints:
Lengthwise bed: ~130 x 185 cm (fits one adult comfortably, tight for two)
Platform bed across width: ~150 x 120 cm (short but fits a couple diagonally or for side sleepers)
Recommended: Custom-cut queen alternative (135 x 185 cm)
Mercedes Sprinter 170" WB:
Lengthwise bed: ~135 x 200 cm (close to a standard double)
More room for fixed bed with storage underneath
Recommended: Full/double equivalent (137 x 190 cm)
Ford Transit High Roof:
Similar width to Sprinter 144
Lengthwise bed: ~130 x 183 cm
Recommended: Custom-cut to exact platform dimensions
Ram ProMaster:
Widest cargo area of the three (~175 cm between wheel wells)
Can fit a widthwise queen-sized bed in some configurations
Recommended: Measure between wheel well covers at sleeping height
Glamping Mattress Guide
Glamping (glamorous camping) is a different use case from van life. Glamping tents and structures are typically semi-permanent, have more floor space than a van, and often sit on wooden platforms rather than metal floors. This changes the mattress equation:
- Standard sizes work: Most glamping tents fit a queen or king mattress without modification
- Thicker is fine: Without the height restrictions of a van, you can use 8 to 12 inch mattresses for home-like comfort
- Moisture is still a concern: Canvas tents breathe better than metal vans, but morning dew and humidity still affect mattresses on platforms. Use a waterproof mattress protector
- Guest comfort matters: If you operate a glamping site, your mattress is a primary driver of guest reviews. Invest in a medium-firm hybrid or latex mattress that appeals to the widest range of sleepers
Moisture Prevention Strategies
This section could save your mattress (and your health). Mould in a van mattress is the number one reason people replace their bedding prematurely:
- Ventilated bed platform: Build or install a platform with air gaps. Slatted wood platforms, perforated plywood, or aluminium mesh panels allow air to circulate under the mattress. This is the single most effective moisture prevention measure
- Moisture barrier: Place a vapour barrier between the van floor and the bed platform. Reflectix or closed-cell foam insulation prevents warm mattress air from reaching cold metal
- Prop your mattress up during the day: When you are not sleeping, stand your mattress on its side or fold it up to allow air circulation on all surfaces. This is especially important in humid climates or cold weather
- Crack a window or run a fan: Even a small amount of airflow dramatically reduces condensation. A roof fan set to exhaust mode pulls moist air out of the van while you sleep
- Moisture-absorbing products: DampRid or silica gel containers placed near the bed platform absorb ambient moisture. Replace them regularly in wet conditions
Bedding Systems for Mobile Living
Your mattress is only part of the sleep equation in a van or glamping setup. The bedding system you choose needs to handle the same temperature swings and moisture challenges as the mattress itself.
For van life, a modular layering system works better than a single heavy comforter. Use a fitted sheet, a lightweight merino wool blanket, and a packable down or synthetic duvet. This allows you to add or remove layers as temperatures change, which happens much faster in a van than in a house. On a single night in spring, you might start with all layers and kick down to just the sheet by morning as the van warms with sunrise.
Sleeping bags designed for van use are another option. Some van lifers prefer a rectangular sleeping bag that opens fully flat, which can double as a duvet. Look for bags rated to minus 5 degrees Celsius for three-season Canadian van life, and minus 15 degrees for winter trips. The advantage of a sleeping bag over traditional bedding is that it contains your body heat more efficiently in an unheated space.
Pillow storage is a practical concern too. Standard pillows take up significant space during the day when you need the bed area for other uses. Compressible pillows made from shredded memory foam or down alternative pack down to about one-third their sleeping size, making them easier to stow in a van's limited storage.
Canadian Van Life Sleep Tips
Canada's climate adds specific challenges for van dwellers:
- Winter insulation: Your mattress platform needs proper insulation underneath. Without it, cold from the van floor transfers directly through the mattress and chills you from below, regardless of how warm your sleeping bag or blankets are
- Four-season versatility: Natural latex handles temperature extremes better than memory foam. It does not get brick-hard in January or swampy in July
- Ventilation in winter: Many van dwellers seal everything up in winter to stay warm, but this traps moisture inside. Keep at least one vent cracked to prevent condensation from soaking your bedding
- Provincial camping rules: Ontario's crown land camping allows 21-day stays on most crown land. British Columbia allows 14 days. Plan your mattress durability around extended boondocking trips
Frequently Asked Questions
What thickness mattress works best in a van?
4 to 6 inches (10 to 15 cm) is the practical range for most van conversions. A 4-inch mattress saves headroom but may feel thin for side sleepers or heavier individuals. A 6-inch mattress provides comfort closer to a standard bed. Avoid anything over 8 inches unless you have a high-roof van with a dedicated sleeping platform that does not double as a seating area.
Can I cut a regular mattress to fit my van?
Foam mattresses (memory foam, latex, polyurethane) can be cut to custom dimensions with an electric carving knife or serrated bread knife. Innerspring and hybrid mattresses cannot be reliably cut because you would expose and damage the coil system. For the cleanest results, order a custom-cut mattress from a foam supplier.
How do I prevent mould under my van mattress?
Use a ventilated bed platform with air gaps, place a vapour barrier between the platform and the van floor, and prop your mattress up during the day to allow both sides to breathe. Running a roof fan on exhaust mode while you sleep helps remove moisture from the air before it condenses.
Is a camping pad good enough for van life?
For occasional weekend trips, a thick self-inflating camping pad works fine. For full-time van living, most people find that a proper foam mattress (4 to 6 inches) provides much better sleep quality and spinal support. The investment in a proper mattress pays off quickly when you are sleeping in it every night.
What mattress is best for a glamping tent?
Since glamping tents usually have more space and sit on solid platforms, you can use a standard 8 to 12 inch mattress. A medium-firm latex or hybrid mattress works well for the widest range of guest comfort. Pair it with a waterproof protector and breathable sheets to handle humidity and outdoor conditions.
