Lifestyle
Construction
Takes the heat out of a bed that sleeps too warm, without replacing it. A layer that carries your heat away instead of holding it, laid straight over the mattress you already have.
-
Moisture-wicking zip-off cover (Coolplus™)
The fibres are woven in a cross shape, which gives them more surface to pull damp away from you and let it dry off — faster than cotton or ordinary polyester manages. It's Oeko-Tex Standard 100 certified, and it unzips for the machine.
-
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, so the heat you give off moves away instead of gathering under you. In laboratory testing, thirty times more air moves through it than through a premium memory foam mattress. It's soft, cushions well, and springs back quicker than memory foam.
-
Two storage straps, included free
Elastic straps at the corners hold it steady all night, so it doesn't slide about or rumple up under the sheet. When you don't need it, they let you roll it up small to store or take with you.
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?
A mattress is a big outlay, and if yours is comfortable but sleeps hot, there's no sense replacing it. This topper lays straight over what you've already got and puts a breathable layer on top. It turns a warm bed into a fresh one for a fraction of what a new mattress costs.
It lets your heat go where ordinary memory foam holds it in, so the heat doesn't gather under you overnight, and the cover pulls the damp away. Two straps come with it, so it stays put on the bed and rolls up small when you want it out of the way.
Ideal for:
- Anyone whose mattress is comfortable but sleeps too hot
- Anyone who wakes up hot and doesn't want to buy a new mattress
- Anyone who wants a bit more cushioning on a firm bed
- Anyone who wants something they can roll up and put away
Depth Options
The one most people choose — a clear difference you'll feel the first night
The deeper of the two — more cushioning, and more cooling with it
Both depths are soft, and both spring back faster than memory foam.
Climate & Cooling
- Cooled from both sides — the cover works at the surface, the foam underneath it
- It moves damp away — the cross-shaped fibres do it faster than cotton or ordinary polyester
- Works all year — it stops you overheating in summer without leaving you cold in spring
Care & Maintenance
Zip-off cover
- Machine wash at 30°C on a gentle cycle
- Mild liquid detergent — no bleach
- Air dry only — never tumble dry it
- Iron on low if you need to
- Wash it every month or two
Measuring Guide
We make the foam to the measurements you provide; the cover then adds a centimetre or two 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.

Frequently Asked Questions
- Will it stay in place on my mattress?
- Yes. The two elastic straps hold it steady on your own mattress all night, so it won't slide off or rumple up.
- Does it come rolled and boxed?
- Yes — vacuum-packed in a 158 × 39 × 39 cm box, with the two free straps in with it.
- How long does it take to expand?
- Usually 95% of its shape and size within the first hour or two. Sometimes it can take 24 hours or so to regain its shape fully.
- What's included?
- The topper, its zip-off cover, the two free straps, and a 3-year guarantee.
- What firmness is it?
- Soft, but it still holds you up, and it springs back quickly as you move.
