Coolplus construction cutaway Triple Layer Construction
Coolplus Custom Mattress lifestyle Lifestyle

Stay cool even in a warm, poorly ventilated room β€” a foam that lets heat escape rather than store it, laboratory-proven 30Γ— more breathable than standard memory foam (Revoβ„’).

  • 3 firmness levels: Medium, Firm, Hard
  • Depths from 15–25 cm
  • 7-year guarantee
  • Moisture-wicking zip-off cover (Coolplusβ„’)
  • A top layer that doesn't hold your heat (Revoβ„’)
  • A springy layer that pushes back as you move (Laytecβ„’)
  • Bonded 3-layer construction — each layer doing a different job
  • Light to lift and reposition on any bed base

Triple Layer Construction

Coolplus triple-layer construction diagram
  1. Moisture-wicking zip-off cover (Coolplusβ„’)

    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 β€” no need to haul the mattress anywhere to freshen it up.

  2. Top layer that draws the heat away (Revoβ„’)

    The internet calls this a cool gel foam. There is no gel in it β€” the foam is made with open cells, so it releases your body heat rather than holding it in. Laboratory-proven 30Γ— more breathable than standard memory foam, so warmth never gathers underneath you on a close, muggy night.

  3. 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.

  4. Firm base layer

    A firm, durable foundation that keeps the mattress true to shape season after season β€” while staying light enough to manoeuvre easily even where access is awkward.

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.

Premium grade foams only. From 39 kg/m³ up to 70. Anything less does not make it into one of our mattresses.

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 top layer moves thirty times more air than memory foam, channelling 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 β€” sleep on the marked face only, no flipping
  • Let it breathe often to keep it feeling fresh
  • Naturally unwelcoming to dust mites

Zip-off cover

  • Cool 30Β°C machine wash on a gentle setting
  • A mild liquid detergent only β€” 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 made 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 β€” though that is entirely down to how you prefer it.

Delivery

  • Free delivery across the majority of mainland England, Scotland and Wales
  • Vacuum-rolled into a compact 158 Γ— 39 Γ— 39 cm carton that's simple to carry

Frequently Asked Questions

How do the cooling and responsive layers work together?
The responsive layer supplies the spring-back while the breathable layer handles the cooling β€” between them you get solid support without the warmth that ordinary memory foam holds in.
What does 30Γ— breathability actually mean?
In lab conditions the breathable 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?
Typically 95% of its custom shape and size returns within the first hour or two; now and then it may take 24 hours or so to regain its shape completely.
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?
Yes. Think of it as a firm base with a soft, cooling surface over the top. You feel the support underneath rather than a hard slab against you.
