Van life has its own mattress challenge: the bed platform is rarely a standard size, space and weight are at a premium, and the mattress often has to fold, flex, or convert. Whether you’re in a factory Class B, a Sprinter conversion, or a DIY build, the right camper van mattress makes the difference between waking up refreshed and waking up sore. Here are the best camper van and Class B mattresses of 2026.

What makes a van mattress different

A camper van bed has to do more with less. It needs to be thin and lightweight (van platforms sit low and weight matters even more than in a big rig), flexible (many van beds fold up during the day or convert from a dinette), and often a non-standard size — vans rarely use a clean Short Queen or Twin. Comfort still matters, but it’s balanced against packability and fit more than in any other rig.

Best overall van mattress: 5-8 inch foam

For most vans, a 5–8 inch foam mattress is the sweet spot — thin and light enough for a low van platform, but thick enough for real comfort. Memory foam contours and isolates motion in a tight space; a firmer polyfoam holds up better if the bed folds daily. Look for CertiPUR-US certification and confirm the height works under your ceiling and any overhead storage.

Best for fold-up or convertible beds: flexible foam

If your bed folds against the wall or converts from a dinette, you need a flexible foam that bends without cracking or losing support. Softer, more pliable foams handle daily folding best. Some van-specific mattresses are even hinged or come in sections to fold cleanly — worth it if you convert the bed every day.

Best for a custom or DIY build: cut-to-fit foam

DIY van builders often have an odd-shaped platform — over a wheel well, tapered at the walls, or an angled corner. A cut-to-fit foam mattress lets you trim the foam to your exact platform with an electric knife. Buy a slightly oversized piece of CertiPUR-US foam and cut to the template of your platform for a perfect, gap-free fit.

How to choose your van mattress

Start by measuring your platform — width, length, and any odd angles — and note your available height under the ceiling. Then decide: a fixed bed can take a normal 6–8 inch foam; a fold-up or convertible bed needs flexible or hinged foam; a custom platform calls for cut-to-fit foam. Keep it light and thin, insist on CertiPUR-US certification, and prioritize a build that matches how your bed is used day to day.

Frequently asked questions

What size mattress fits a camper van? It varies widely — vans rarely use standard sizes. Measure your platform and consider cut-to-fit foam for odd shapes. See our RV mattress sizes guide.

How thick should a van mattress be? Usually 5–8 inches — thin and light for a low van platform, but enough for real comfort. Confirm ceiling clearance.

Can I cut a foam mattress to fit my van? Yes — high-density foam can be cut to your platform’s shape with an electric knife, which is ideal for DIY builds with wheel wells or angled corners.

What’s best for a fold-up van bed? Flexible or hinged foam that bends without losing support, so it holds up to daily folding.

The bottom line

Van life rewards a mattress that’s thin, light, and shaped for your space. A 5–8 inch foam is the all-around pick for a fixed bed, flexible or hinged foam handles fold-up and convertible setups, and cut-to-fit foam solves odd DIY platforms. Measure carefully, mind your ceiling clearance, keep it light, and you’ll sleep well in even the smallest rig.
