Four Layer Construction
-
CoolGuard™ Cover with Revo® Cool Gel
Here the cool gel lives inside the cover itself — a gel layer worked directly into the zip-off cover, so cover and cooling are a single thing. It reads cool the instant you lie back and helps hold an even temperature all night, and because it's laboratory-proven 30× more breathable than standard memory foam, warmth never gathers below you. Unzip the cover and the cool-gel layer comes away with it, making care simple.
-
Vasco®60 Premium Memory Foam
Premium-grade memory foam that yields to your body and supports your shoulders, hips and back for deep, genuine pressure relief. It draws in movement as well, so a partner who fidgets is far less likely to rouse you.
-
Laytec™ Responsive Support Layer
Set below the thick memory foam, a responsive layer bears the load and keeps your spine in line — so you melt into plush comfort up top while remaining firmly held from beneath.
-
Premium Foundation Layer
A firm, durable and airy foundation that keeps the mattress true to shape season after season, while staying light enough to move easily even where access is tight.
Why Choose Grand Crescent?
Memory foam delivers that wonderful, body-hugging embrace — but it tends to hold heat in. The Grand Crescent™ is our flagship reply. Thick layers of premium memory foam make it truly indulgent underneath you: you settle right into it and it supports every pressure point, while a responsive layer below keeps you firmly held. And with the cool gel sealed into the cover, that comfort arrives without the warmth memory foam usually traps.
This is the mattress for anyone who wants their bed to be the centrepiece of the room: a made-to-measure flagship in four layers of authentically premium materials, offered in our two most generous depths, with the foam covered by an 8-year guarantee.
Ideal for:
- Anyone who adores the embrace of memory foam yet overheats on it
- Those after deep pressure relief with solid support beneath them
- Couples — the memory foam draws in movement, so you're disturbed less
- Anyone dressing a premium bed who simply wants the best we make

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
Cooling Cover
- Professional dry clean only
- Never machine wash or hand wash it
- Keep bleach and harsh chemicals away
- Never put it through a tumble dryer
Measuring Guide
The Grand Crescent™ is bespoke to your room: your foam is cut precisely to the custom size you send us, and 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 memory foam and cooling work together?
- The memory foam wraps around you and eases pressure, while the cool-gel cover carries heat away — giving you all the comfort of memory foam without the warmth it normally holds in.
- What do the four layers do?
- Above the memory foam sits a responsive layer that rebounds as you move and holds your spine in line, set over a firm, ventilated base. Together they pair soft contouring with dependable support.
- 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 fully settle in.
- What's included?
- You receive the mattress with its zip-off cooling cover, a care guide and an 8-year guarantee on the foam.
- Is the Firm option suitable for everyday use?
- Yes indeed — it delivers therapeutic backing while staying cool underneath you, whichever way you sleep.
