Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw is comfort without the heat. Traditional memory foam moulds to your body, relieving pressure at the shoulders and hips, but it can trap warmth. Here the foam is infused with graphite, which Silentnight says actively transfers heat away from the body, making it 15% cooler than standard memory foam. Beneath that sit 2000 Mirapocket springs in individual pockets, which means each spring responds to your movement separately, so you get zoned support and less disturbance from a restless partner. The medium firmness suits most sleepers, and the 60-night trial gives you time to be sure. Delivery is quoted at 14 days, a slightly longer wait than some.
Key Features & what's inside
- Memory Cool™. A graphite-infused memory foam that moulds to your body, relieving pressure and absorbing energy as you move. The graphite actively transfers heat away from you, which Silentnight says creates a sleep environment 15% cooler than standard memory foam.
- Mirapocket® springs. 2000 Mirapocket springs sit in individual pockets, each responding to your movement independently. In practice that means zoned support where you need it and less motion transfer across the bed.

Who's it NOT for?
If you prefer a firm, supportive surface with little sink, the medium feel and pillow top here will likely be too soft, particularly for heavier back or front sleepers. And if you actively dislike the slow, hugging feel of memory foam, no amount of cooling graphite will change that. Fans of a springy, traditional feel should look elsewhere.

Is the Silentnight Memory Cool 2000 good for hot sleepers?
It is designed with hot sleepers in mind. The memory foam is infused with graphite that transfers heat away from your body, and Silentnight says this makes it 15% cooler than standard memory foam. If overheating is your main worry with memory foam, this addresses it directly.
How firm is the Silentnight Memory Cool 2000 Pillow Top?
Silentnight rates it as medium. Combined with the pillow top and memory foam layer, expect a cushioned, contouring feel rather than a firm one. That suits most side and combination sleepers, although those who want a firmer surface may find it a little soft.
Does the Silentnight Memory Cool 2000 come with a trial?
Yes. Silentnight offers a 60-night trial, described as its sleep guarantee, so you have two months to decide whether the mattress suits you. It also comes with a 5 year warranty.
How deep is the Silentnight Memory Cool 2000 mattress?
It is 31cm deep, and that depth is consistent across all sizes, from UK Single up to UK Super King. It is a fairly deep mattress, so check your fitted sheets will stretch to fit.
How much does the Silentnight Memory Cool 2000 cost?
Prices range from £650 to £1,240 depending on size, with sizes running from UK Single to UK Super King. That is a mid-to-upper price point, justified in part by the 2000 pocket springs and the graphite-infused cooling foam.
