Layer Details
- Memory Cool™. A graphite-infused memory foam that moulds to your body to relieve pressure, which means less tossing to find a comfortable position. The graphite actively transfers heat away from you, and Silentnight claims this makes it 15% cooler than standard memory foam.
- Mirapocket® springs. 2000 Mirapocket® springs, each held in its own individual pocket so they respond to every movement independently. In practice that means zoned support for your back and less motion transfer across the bed.
Layer details from silentnight.co.uk product page, September 2026.
- Spreading room for one: At 30cm wider than the UK single, this size lets a solo adult roll over and stretch without an edge appearing under an elbow.
- Fits compact rooms: It's 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Cooling foam without the squeeze: The graphite-infused Memory Cool™ layer draws heat away from you, so a smaller room with less airflow doesn't have to mean a warmer night.
- Springs that suit occasional sharing: The 2000 pocket springs respond independently, so two guests sharing for a weekend won't feel every turn the other makes.
- Standard 4ft sizing: The small double is a standard UK size, so frames and fitted sheets are easy to find, with a normal double duvet on top.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, you're furnishing a box room, loft conversion or studio where every centimetre of width matters, or you're setting up a guest room that only occasionally hosts a couple. Allow at least 2.4m x 2.8m of floor space and you'll still have room to walk round it.
Consider another size if...
You share the bed every night, as 120cm of width feels snug for two adults long term. We'd recommend the UK double instead, which is 15cm wider; allow at least 2.6m x 2.8m for it.

Is a small double Memory Cool 2000 big enough for a couple?
For occasional nights, yes. The 2000 Mirapocket® springs move independently, so two guests sharing won't disturb each other much, which makes this size a sensible guest room choice. For a couple sleeping together every night, 120cm of width is a compromise, and the UK double, 15cm wider, would suit better.
What room size do I need for the Silentnight Memory Cool 2000 small double?
We suggest allowing at least 2.4m x 2.8m. That leaves space to open the door, get in on either side and add a small chest of drawers. If your room is tighter than that, measure carefully before ordering, because at 31cm deep this is a fairly tall mattress and it will dominate a very small space.
Is the small double a good upgrade from a single for a teenager?
It's a popular one. The UK small double is 30cm wider than the UK single but exactly the same length, so the bed grows sideways rather than eating into the room's length. A teenager gets adult-sized sleeping space, and the medium feel with pressure-relieving memory foam suits most sleep positions.
How much smaller is the small double than a king size?
The UK small double is 30cm narrower and 10cm shorter than the UK king. That's a meaningful difference: a king needs a room of at least 2.7m x 2.9m by our guidance, while the small double works in rooms from 2.4m x 2.8m. Taller sleepers should note the length gap as well as the width.
What bedding fits the Memory Cool 2000 in a small double?
You'll need small double, or 4ft, fitted sheets, and this mattress is 31cm deep, so check the sheet's stated depth before buying. Deep-pocket versions are safer. For the top layer, a standard double duvet is the usual pairing, and 4ft is a common enough UK size that bedding is easy to find.
