Triple Layer Construction
Lifestyle
Rest cool when the van's shut up for the night — a foam that lets heat escape rather than store it, laboratory-proven to breathe 30× better than ordinary memory foam (Revo®), so trapped heat and condensation never wreck your sleep.
- 3 firmness levels: Medium, Firm, Hard
- Depths from 15–25 cm
- 7-year guarantee
- Moisture-wicking zip-off cover (Coolplus®)
- A top layer that doesn't hold your heat (Revo®)
- A springy layer that pushes back as you move (Laytec™)
- Bonded 3-layer construction — not one slab of foam
- Light enough to handle on your own
Triple Layer Construction
-
Moisture-wicking zip-off cover (Coolplus®)
Pulls body heat and the damp that gathers in a closed van away from the surface, keeping it dry until morning. Unzip it and it's in the wash within seconds — no hauling the whole mattress out through the sliding door to freshen it up.
-
Top layer that draws the heat away (Revo®)
The trade calls this a cool gel foam. There is no gel in it — the foam is made with open cells, so it releases your body heat rather than bottling it up. Laboratory-proven 30× more breathable than standard memory foam, so warmth doesn't pool beneath you when the van is sealed against the cold outside.
-
Springy middle layer that stops you sinking
Bounces back the moment you shift, so you rest on the surface instead of sinking into a hollow. It holds your spine level whichever way you lie, night after night.
-
Firm base layer
A firm, hard-wearing base that keeps its shape season after season, and stays light enough to handle on your own when space in the van is at a premium.
Why Choose Coolplus?
A campervan is a small, sealed box once the doors are shut, and it holds warmth and overnight breath-damp far longer than a bedroom at home. Crack a roof vent or window at a quiet stopover and you let in cold, noise or condensation instead — so most of us end up sleeping buttoned up. An ordinary foam mattress simply soaks up that heat and hands it straight back to you. The Coolplus is made for precisely this: its cool gel top layer channels warmth away rather than storing it, while the responsive layer underneath springs straight back to keep you aligned and supported. The result is genuinely cool, settled sleep without that sunk-in, stuck-fast feeling.
Ideal for:
- Anyone bedding down in a shut-up campervan, day van or pop-top that turns warm and airless overnight
- Hot sleepers who overheat and wake clammy on standard foam
- Those who can't get on with the slow, sink-in feel of memory foam
- Anyone who wants firm support without giving up the cooling

Measuring Guide
We cut every mattress to the precise measurements you send us, and the cover then adds a few millimetres to the final size.
If your bed drops into a snug recess — as many VW and self-build conversions do — or you want slack for tucking bedding in, shave a little off your figures. It comes down to what you prefer.
Delivery
- Free delivery to most addresses in England, Scotland, and Wales

Frequently Asked Questions
- How do the cool gel and responsive layers work together?
- The responsive layer supplies the spring back while the cool gel layer handles the cooling — between them you get proper support without the heat that builds under standard memory foam.
- What does 30× breathability actually mean?
- In laboratory testing the cool gel layer moved 30 times more air than traditional memory foam — that's what stops heat and moisture collecting inside a closed-up van.
- How long does a rolled mattress take to expand?
- Give it 1–2 hours to open out to size, and 12–24 hours for the cooling and responsive layers to reach full performance.
- What's included?
- The mattress itself, its Coolplus zip-off cover, care instructions and a 7-year guarantee.
- Is the Firm option suitable for everyday use?
- Yes. Firm gives you more support underneath while the top layer still cushions and cools, whether you're away for a weekend or living in the van full-time.
