The Ultimate Guide to Campervan Mattresses

Key Takeaways
Considerations	Size: Campervans rarely use standard bed sizes, so always measure the actual sleeping platform, including any corner cuts, angles, or obstacles. Thickness: Thicker mattresses offer more comfort but leave less headroom and may be harder to store. Sleep Style: Side sleepers benefit from softer mattresses that cushion hips and shoulders. Back sleepers generally prefer medium-firm support for spinal alignment. Weight: Every extra kilogram affects handling and fuel economy. Foam mattresses are the lightest option. Pocket springs add more weight but are more supportive. Durability: Campervan mattresses face temperature swings, humidity, and constant movement. Choose resilient materials and use a removable, washable cover. Ventilation: Poor airflow leads to condensation and mould. Prioritise breathable materials such as wool or latex, and ensure the van is ventilated while sleeping.
Bed Types	Fixed: Permanently installed and always ready to sleep in. May need a custom mattress to fit around wheel arches or cut edges. Rock & Roll / RIB: Convert from rear seating to a flat bed. RIB beds bolt directly to the chassis for extra stability. A memory foam topper is a popular addition for both types. Fold-Down: Stowed during the day to keep living space open. Mattresses usually require a vertical or horizontal split, to allow folding. Pop-Top: Fitted into a roof alcove that opens and closes. A slim 3–5 cm mattress is typically required if you want to leave it in the roof when lowered.
Materials	Shapes include rectangular, cut corner (French Bed – nearside or offside), island (curved base, optional bolster), and angled/circular cut for wheel arches and furniture.
Recommended Depth	Memory Foam: Conforms to body shape, reduces motion transfer, and is relatively lightweight. Cool blue or gel-infused memory foam have a lower rate of heat retention. Natural Fillings: Hypoallergenic, breathable, and resistant to dust mites and mould. Heavier than foam alternatives. Hybrid: Combines memory foam comfort with pocket spring support. The premium choice where headroom and payload allow it.
Using Household Mattresses	Not recommended as standard sizes rarely fit campervan platforms. 20–30 cm depth is too thick for pop-tops. The added weight hurts fuel economy and handling.
Winter Storage of Bedding	Remove all loose bedding before storing over winter. If possible, leave roof vents slightly open, use calcium chloride moisture absorbers, and consider a small dehumidifier to prevent mould.
Pop-Top Weight Limits	Most roofs comfortably support two average adults. Avoid sitting on the edge with legs hanging down, don't exceed the stated limit, and inspect the roof mechanism regularly.
Improving Comfort	A quality memory foam topper, proper sheets and blankets, good ventilation, a washable mattress cover, adequate insulation, and (for families) a child safety net all make a significant difference.

Ask any campervan traveller, and they'll tell you the same thing: a bad night's sleep can ruin even the best adventure. Your campervan bed is one of the most important investments you can make, and it deserves serious thought.

Whether you're planning a conversion or upgrading your current sleeping arrangements, this guide covers everything you need to know, from choosing the right mattress type and material to storing your bedding over winter and making your camper as cosy as possible.

Considerations

When looking at different mattress types, there are several key factors that need careful thought:

Size and Dimensions

Campervans come in all shapes and sizes, so the sleeping area is rarely a standard shape. Some layouts have corner cuts, angled edges, or split sections. Always measure the actual sleeping platform, length, width, and any unusual angles, before ordering. If you don't yet have a bed platform, measure the available floor or roof space and account for any obstacles, such as wheel arches or cabinets.

Thickness

A thicker mattress generally offers better cushioning and support, but in a campervan, this must be balanced against the available headroom and storage requirements when the bed is not in use. For pop-top roofs, the thickness of your mattress will determine whether it can stay in the roof when it's lowered or if it will need to be stored elsewhere.

Sleeping style

Side sleepers tend to sleep better with softer mattresses that cushion the hips and shoulders, while back sleepers usually prefer a medium-firm surface for spinal alignment. Think about how you sleep at home and try to replicate those conditions on the road.

Weight

Every kilogram you add to a campervan affects handling and fuel economy, so lighter materials like foam are often preferable over heavier options such as latex or pocket springs. That said, if comfort is the priority and weight isn't a concern, don't let this stop you from choosing a more supportive mattress.

Durability & Maintenance

A campervan mattress is exposed to temperature fluctuations, humidity, and more movement than a standard bed at home. Choose materials that can handle these conditions, and always opt for a removable, washable cover or bedsheets to make keeping the mattress clean much simpler, especially if you travel with children or pets.

Ventilation

Campervans are prone to condensation, and a mattress with poor airflow will quickly become damp, leading to mould. Make sure the campervan is well-ventilated when sleeping and look for mattress materials that allow air to circulate like wool or latex.

Campervan Bed Types

Which campervan mattress is best for you will depend on what kind of bed you have. Here are the main campervan bed options available:

Fixed Beds

A fixed bed is permanently installed in the campervan and so doesn’t require converting. These beds tend to require a mattress cut to a specific shape, particularly if the van layout includes wheel arches or corner angles.

Rock & Roll Beds / RIB Beds

Rock and roll beds are an iconic feature of classic campervan conversions, particularly VW builds. It functions as a rear seat during the day and folds forward to create a flat sleeping surface at night. Standard rock and roll beds typically measure around 4’2” x 6’ (129cm x 184cm).

The RIB bed is a step up from a standard rock and roll in terms of safety and build quality. Rather than being screwed into the van floor, a RIB bed is bolted directly to the vehicle chassis and offer a flatter and more supportive sleeping surface.

Fold-Down Beds

Fold-down beds are stored away during the day, which helps to keep the living area open and flexible, and then folded down at night for a lightweight sleeping option. Mattresses for these beds typically require a vertical or horizontal split to allow folding (which we can provide as a bespoke order).

Pop-Top Roof Beds

Pop-top roofs provide an elevated sleeping area above the main van body, helping to maximise floor space below. Pop-top roofs typically have a standard rectangular bed platform with a plywood base, onto which you place a dedicated mattress. The key constraint is thickness; if you want to leave the mattress in the roof when it's lowered, you need a slim depth. This is typically around 3-5cm but make sure you measure your closed roof space to make sure. If you're happy to store the mattress elsewhere when driving, you have far more options available.

One other consideration with pop-tops, especially for winter use, is that the canvas roof offers less insulation than the van body and can become cold quickly.

Mattress Materials

Choosing your mattress core and filling is an important decision as the materials you choose affect not just comfort, but also breathability, durability, and weight.

Typically, the core layer of the mattress will be lightweight foam. The other main option is pocket springs, which are more supportive than foam, but are also heavier and require more depth. Supporting layers can be made from materials including the following:

Memory Foam

Memory foam is one of the most popular choices for campervan mattresses. It conforms to the shape of your body, providing personalised support and pressure relief, and is excellent at minimising motion transfer, ideal if you're sharing the bed. Memory foam is relatively lightweight compared to spring options, which makes it practical for van use.

Memory foam is known for retaining heat, which can be a problem for warm sleepers. If this is a concern, look for cool blue memory foam or gel foam, which incorporates open-cell technology and cooling gel layers to improve airflow and reduce heat retention.

Natural Fillings

Natural fillings like wool and latex are hypoallergenic, breathable, and resistant to dust mites and mould, making them well-suited to the campervan environment. They offer a firm, responsive feel and excellent durability, but can be heavier than foam alternatives.

Hybrid Mattresses

Hybrid mattresses combine a memory foam comfort layer on top with a pocket spring support base. This blends the pressure-relieving properties of foam with the structured support of springs, offering the best of both worlds. For campervans where headroom and weight allow, a hybrid mattress is an excellent premium choice.

Can You Put a Normal Mattress in a Campervan?

While it is technically possible to put a standard mattress in a campervan, they will face several issues that make this inadvisable:

Size: Campervan sleeping platforms almost never correspond to standard UK bed sizes; they tend to be unusual lengths, widths, or shapes. Forcing a standard mattress into a non-standard space means it won't fit properly, making it far less secure and comfortable. If you try to cut your mattress to better fit e.g. for a corner cut base, you will also invalidate the warranty.
Thickness: A standard household mattress is typically 20–30cm deep, which is far too thick for a pop-top roof bed. Even for a fixed floor bed, a full-depth mattress may leave inadequate headroom.
Weight: Standard mattresses are heavier than purpose-made campervan alternatives, which will affect your van’s performance and fuel consumption.

Can You Leave Bedding in a Camper Over Winter?

This is one of the most frequently asked questions among campervan owners who park up their vehicle between seasons. It's generally not advisable to leave soft bedding in a campervan over winter without taking some precautions.

The main risk is damp and mould. When a campervan sits unused in cold weather, any residual moisture inside the van has nowhere to go. Without ventilation or heating to keep air circulating, this moisture settles on soft furnishings, including mattresses, duvets, pillows, and cushions. Over weeks and months, this creates the perfect conditions for mould and mildew to develop.

Bedding items like duvets, pillows, blankets, and sheets are particularly vulnerable, as they absorb moisture readily. Make sure you remove all loose bedding before storing your campervan for winter and bring them indoors where they can be kept warm and dry.

For fitted mattresses and seat cushions, ensure the van is as well-ventilated as possible during storage. Leave roof vents slightly open if the vehicle is stored in a secure location, and open internal cupboard doors to allow air to circulate. Consider placing calcium chloride moisture absorbers inside the van to pull excess humidity from the air. If you have access to mains electricity at your storage location, a small dehumidifier on a timer can make a significant difference as well.

Also check that there are no leaks, even a tiny ingress of water can cause significant mould damage over winter. Inspect the pop-top canvas, window seals, and roof joins carefully before putting the van away for the season.

When you return to the van in spring, air it out thoroughly before use, check the mattress and cushions for any signs of mould or damp patches, and launder all bedding before sleeping on it. If mould has developed, treat affected surfaces promptly with a specialist mould remover or diluted hydrogen peroxide, wearing protective gloves.

How Much Weight Can a Campervan Pop-Top Bed Hold?

The weight capacity of a campervan pop-top bed depends on the manufacturer of the roof and the specific conversion, so always check the documentation. Generally, campervan pop-top roof beds are designed to comfortably support two average adults sleeping side by side.

The important things to watch out for are:

Not sitting on the edge of the bed with legs hanging down, which concentrates weight at the weakest point of the platform.
Not exceeding the stated limit.
Ensuring the roof mechanism and supports are regularly inspected and in good condition.

If in doubt, contact your roof manufacturer directly with your specific model details, and they will be able to confirm the rated weight capacity for your setup.

How to Make a Campervan Bed More Comfortable

Even the best campervan bed rarely matches the comfort of a good domestic mattress straight out of the box. Here are the most effective ways to improve your sleeping experience on the road:

Invest in a quality mattress topper: For rock and roll beds and RIB beds especially, a purpose-made memory foam mattress topper is one of the most impactful upgrades you can make. Memory foam toppers conform to your body shape and significantly reduce the firmness of the underlying platform.
Choose high-quality bedding: Use proper sheets and blankets rather than sleeping bags wherever possible. Choose moisture-wicking fabrics that won't feel damp or clammy in the morning. Lightweight down or synthetic duvets designed for travel are ideal, as they compress down for storage but provide genuine warmth.
Ensure good ventilation: Stuffiness and condensation are the enemies of a good night's sleep in a campervan. Always ensure there is some airflow by cracking a roof vent, using a mesh window cover, or running a low-power roof fan. A well-ventilated van is also far less prone to morning dampness on your bedding.
Add a removable, washable mattress cover: A well-fitting cover keeps your mattress clean, extends its life, and makes it easy to refresh between trips.
Consider insulation: Particularly in a pop-top roof, the difference between a warm and cold night's sleep often comes down to how well the van is insulated. A good quality sleeping bag or double-weight duvet for autumn and winter trips makes a significant difference, as does a diesel or propane heater if you camp in cooler months.
Think about children's safety: For families using the pop-top bed for children, a child safety net that fits across the open section of the roof bed prevents children from rolling out during the night.
