- 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 to lift and reposition on any bed base
Triple Layer Construction
-
Moisture-wicking zip-off cover (Coolplus®)
Pulls heat and moisture away from you across the night for a drier, cooler surface. The whole cover unzips in moments and drops straight into the wash — no need to haul the mattress anywhere 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 holding it in. Laboratory-proven 30× more breathable than standard memory foam, so warmth never gathers underneath you on a close, muggy night.
-
Springy middle layer that stops you sinking
Rebounds the instant you shift position, so you're never left feeling stuck in a hollow. It carries your spine evenly no matter how you lie.
-
Firm base layer
A firm, durable foundation that keeps the mattress true to shape season after season — while staying light enough to manoeuvre easily even where access is awkward.
Why Choose Coolplus?
Snug bedrooms, attic rooms and small box rooms can become heat traps, and on a warm night a conventional foam mattress simply hangs onto that warmth. The Coolplus tackles the problem head-on, built to a bespoke custom size for whatever bed you're dressing. Its cool gel top layer channels heat away rather than storing it, while the responsive layer below rebounds fast to keep you aligned and well supported. What you get is genuinely cool, settled sleep with none of that sunk-in, hard-to-move sensation.
Ideal for:
- Anyone in a warm, stuffy room where the air barely moves at night
- Naturally hot sleepers who overheat on everyday foam
- Those put off by the slow, sinking sensation of classic memory foam
- Anyone who wants firm support without giving up the cooling

Care & Maintenance
Mattress
- Single-sided build — sleep on the marked face only, no flipping
- Turn it end to end now and then so it wears evenly
- Let it breathe often to keep it feeling fresh
- Naturally unwelcoming to dust mites
Zip-off cover
- Cool 30°C machine wash on a gentle setting
- A mild liquid detergent only — never bleach
- Dry naturally in the air
- A low iron if it needs one
- Freshen it every one to two months
Measuring Guide
Because each Coolplus is a bespoke, custom-size build, your foam is cut precisely to the measurements you send us; once the cover is fitted, it adds a few millimetres to the final dimensions.
Where the bed drops into a snug recess, or you like a little slack for tucking sheets in, it can help to trim your figures slightly — though that is entirely down to how you prefer it.

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 solid support without the warmth that ordinary memory foam holds in.
- What does 30× breathability actually mean?
- In lab conditions the cool gel layer moved air 30 times more freely than conventional memory foam, which is what stops heat and damp from gathering.
- How long does a rolled mattress take to expand?
- Around 1–2 hours to take shape, with a further 12–24 hours for the cooling and rebound to reach full performance.
- What's included?
- You receive the mattress with its Coolplus zip-off cover, a care guide and a 7-year guarantee.
- Is the Firm option suitable for everyday use?
- No. Firm gives you more support underneath while the top layer still cushions and cools, so it stays comfortable whichever way you sleep.
