Construction

Coolplus topper with storage straps
  1. Coolplus® Zip-Off Cover

    Woven with plus-shaped fibres that create more surface area to draw sweat away and let it evaporate — wicking moisture faster than cotton or standard polyester. Oeko-Tex Standard 100 certified, and it unzips for machine washing.

  2. Revo® Cooling Performance Layer

    A cool-gel foam layer that's laboratory-proven 30× more breathable than standard memory foam, so heat doesn't build up beneath you. Soft, with good pressure relief and a quicker spring-back than traditional memory foam.

  3. Two FREE Secure-Fit Storage Straps

    Elastic corner straps hold the topper firmly in place in use, and let you roll it up compactly to store or take with you when you don't need it.

Why Choose This Topper?

A good mattress is a big outlay — and if yours is comfortable but sleeps hot, you don't need to replace it. This topper lays straight over your existing van mattress and adds a cool-gel layer on top, turning a warm bed into a cool, fresh one for a fraction of the cost of a new mattress.

The cool gel breathes far more freely than ordinary memory foam, so heat doesn't build up overnight, while the cover's plus-shaped fibres draw moisture away. And because it comes with two secure-fit straps, you can strap it down in use or roll it up to store or move on — handy if you're chasing the sun.

Ideal for:

  • Anyone whose mattress is comfortable but sleeps too hot
  • Hot sleepers who want cooling without buying a new mattress
  • Those wanting extra cushioning and pressure relief on a firm bed
  • Travellers who want a topper they can roll up and move easily

Depth Options

5 cm

A popular choice — a noticeable cooling and comfort boost that works with your existing mattress

7.5 cm

The premium depth — deeper cushioning and cooling, with more pressure relief

Both depths are medium firmness with adaptive support.

Climate & Cooling

  • Dual-action cooling — the cover and the cool-gel foam regulate temperature from both the surface and the core
  • Superior moisture management — plus-shaped fibres move moisture away more efficiently than cotton or standard polyester
  • All-season performance — keeps you from overheating in warm weather while staying comfortable when it's cooler

Care & Maintenance

Cooling Cover

  • Machine wash at 30°C on a gentle cycle
  • Use mild liquid detergent — no bleach
  • Air dry only — do not tumble dry
  • Iron on low if needed
  • Wash regularly to keep it fresh

Measuring Guide

We cut the foam to the exact dimensions you provide; the cover then adds a small amount to the finished size.

If your bed sits in a tight recess, or you'd like room for tucking in bedding, we recommend reducing your measurements though this remains a personal preference.
