Silentnight Memory Cool 2000 Mattress

Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.

If you've written off memory foam because you sleep hot, this is the sort of mattress designed to change your mind. The graphite-infused Memory Cool™ layer moulds to your body and relieves pressure, which means you get that cradled feeling without the usual heat build-up. Beneath it, 2000 individual pocket springs respond to your movements separately, so a restless partner is less likely to disturb you and your spine gets zoned support where it needs it. The medium firmness suits most sleepers, although anyone who prefers a very firm surface may find it a touch soft. Add the 60-night trial and 5-year guarantee, and it's a fairly low-risk purchase.

Warm sleepers
The graphite-infused Memory Cool layer is designed to draw heat away from your body, giving you memory foam comfort without the usual heat build-up.

Couples
Each of the 2000 pocket springs sits in its own pocket and moves independently, so a restless partner is less likely to disturb you.

Side sleepers
The memory foam layer moulds to your body and relieves pressure, which means a cradled feel around the shoulders and hips on a medium surface.

Combination sleepers
Because the pocket springs respond to each movement separately and the foam moulds to you, changing position should mean less tossing to find a comfortable spot.

Back sleepers
Zoned support from the 2000 Mirapocket springs sits beneath the moulding foam, so your back gets support where it needs it on a medium feel.

If you like a firm, supportive-feeling surface, the medium tension here may feel a little soft for you. Equally, purists who dislike the slow, sinking feel of memory foam should look at a traditional sprung or latex option instead, as the moulding sensation is central to this mattress.

Is the Silentnight Memory Cool 2000 good for hot sleepers?

It's designed with hot sleepers in mind. The Memory Cool™ layer is infused with graphite particles that transfer heat away from your body, and Silentnight says this makes the surface 15% cooler than standard memory foam. No mattress guarantees a cool night, but this one directly targets the problem.

How firm is the Silentnight Memory Cool 2000?

Silentnight rates it as medium. That suits most back and side sleepers, although if you're a heavier build or simply prefer a firmer surface, you may find it slightly softer than you'd like.

Does the Silentnight Memory Cool 2000 come with a trial?

Yes. Silentnight offers a 60-night trial on this mattress, alongside a 5-year guarantee, so you have two months to decide whether it suits you.

How much does the Silentnight Memory Cool 2000 cost?

It depends on the size you choose, and the price table on this page shows the current price for each size. It's available in UK Single, Small Double, Double, King and Super King.

How deep is the Silentnight Memory Cool 2000 mattress?

It's 31cm deep, so check your fitted sheets will stretch to a deeper mattress before it arrives. Silentnight lists delivery at 14 days.
