Construction

Lay a cool, fresh finish over the bed already fitted in your motorhome — a breathable topper laboratory-proven 30× more breathable than memory foam.

Coolplus topper with storage straps
  1. Moisture-wicking zip-off cover (Coolplus™)

    Its cross-section fibres widen the surface area to lift perspiration off the skin and hurry it into the air, moving damp away quicker than cotton or plain polyester manages. Oeko-Tex Standard 100 certified, and the full cover unzips to drop straight in the washing machine.

  2. Breathable comfort layer that carries the heat away (Revo™)

    The internet calls this a cool gel foam. There is no gel in it — the foam is made with open cells, laboratory-proven 30× more breathable than ordinary memory foam, so heat never gathers beneath you. It stays soft, eases pressure points well, and recovers its shape faster than classic memory foam.

  3. Comes with two free storage straps

    Elasticated corner straps grip the topper to your mattress through the night, then unclip so you can wind it down small — simple to tuck in a locker or the garage, or pull out just for the nights you fancy it.

A hand was held on each foam, then lifted off. These are heat pictures of what it left behind — red is warm, blue is cool.

A minute on, the memory foam is still holding the heat. Ours has let it go. That is what we mean when we say it sleeps cooler. Heat pictures by The Vita Group, who make the foam for us.

Why Choose This Topper?

Swapping out a fixed motorhome mattress is rarely cheap or straightforward, so if yours is comfortable but sleeps warm, there's no need to tear it out. This topper simply rests over whatever is on the bed and finishes it with a layer that moves thirty times more air than memory foam, turning a stuffy berth into a cool, refreshed one for a small fraction of what a full replacement would cost.

The foam releases your heat far more freely than standard memory foam, so heat doesn't gather as the hours pass, while the plus-shaped fibres in the cover carry moisture away from you. Two secure-fit straps are included, so you can fix it down as you sleep or roll it up between trips — handy on longer drives to somewhere warm.

Ideal for:

  • Owners whose fixed rear bed is comfortable enough yet runs far too hot
  • Warm sleepers after a cooler night without paying out for a new mattress
  • Anyone wanting a softer, kinder surface laid over a hard factory berth
  • Tourers who need a topper that packs down small between journeys

Depth Options

5 cm

The most popular pick — a clear cooling and comfort lift that pairs with the mattress you already have

7.5 cm

The deepest option — fuller cushioning, extra cooling and more pressure relief

Both depths are soft to settle into, and both lift back into shape as soon as you move.

Climate & Cooling

  • Cooling on two fronts — the cover cools at the surface while the foam works at the core, meeting heat from both sides
  • Better moisture control — plus-shaped fibres shift damp away more effectively than cotton or plain polyester
  • Comfort all year — keeps you from overheating on warm nights yet stays snug when the temperature falls

Care & Maintenance

Zip-off cover

  • Machine wash cool at 30°C on a gentle setting
  • Mild liquid detergent only — never bleach
  • Let it dry naturally — no tumble drying
  • A cool iron if it needs it
  • Give it a regular wash to keep it fresh

Measuring Guide

Give us the sizes and we make the foam to fit; keep in mind the cover adds a couple of millimetres once it's fitted.

Where your motorhome bed drops into a tight moulded recess, or you prefer a little room to tuck sheets beneath, trim a fraction from your figures — entirely down to taste.

Delivery

  • Free delivery to most parts of England, Scotland and Wales
  • Rolled and vacuum-packed into a 158 × 39 × 39 cm box for easy carrying

Frequently Asked Questions

Will it stay in place on my mattress?
It stays put — the pair of elasticated corner straps anchor it to the mattress already on your bed, then release so it rolls up tidily the moment you don't need it.
Does it come rolled and boxed?
Yes — it turns up vacuum-packed in a 158 × 39 × 39 cm box, with the two free storage straps packed in alongside.
How long does it take to expand?
It usually regains 95% of its shape and size within an hour or two of unrolling; occasionally it can take around 24 hours to regain its shape fully.
What's included?
You get the topper, its zip-off cooling cover, a pair of free secure-fit storage straps, and a 3-year guarantee.
What firmness is it?
Soft to settle into, and it lifts back into shape as soon as you move.
