Layer Details
- 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.
Layer details from silentnight.co.uk product page, September 2026.
- Real stretching room for one: At 120cm wide, a solo sleeper gets a proper spread across the slow, cradling pillow top rather than the narrower confines of a UK single.
- Fits rooms a double overwhelms: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Cooling that suits a snug room: Smaller bedrooms often run warmer, so the graphite-infused foam, which Silentnight says sleeps 15% cooler than standard memory foam, is a sensible match here.
- Standard 4ft bedding and frames: Small double is an established UK size, so fitted sheets and frames are easy to find, even though the mattress itself is 31cm deep, so choose deep-fitted sheets.
- Comfortable for occasional sharing: The 2000 Mirapocket springs respond individually, so a guest room couple sharing for a weekend won't feel every turn the other makes.
This size suits you if...
You sleep alone most nights and have outgrown a UK single but can't spare the width a UK double demands, your box room, loft conversion or studio needs a bed that still leaves walking space, or you're furnishing a guest room where couples stay occasionally rather than nightly. The soft, cushioned pillow top rewards a solo sleeper who can use the whole surface.
Consider another size if...
You share the bed every night, because 120cm gets tight for two adults long term, especially on a soft pillow top where you both settle into the surface. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room.

Is a UK small double big enough for two people on the Memory Cool 2000?
For occasional nights, yes. The 2000 pocket springs keep movement localised, so a visiting couple will sleep well enough for a weekend. For every night, two adults on 120cm of soft pillow top will feel cramped, particularly if either of you moves around. Full-time couples should look at the UK double, which is 15cm wider.
What room size do I need for the small double Memory Cool 2000?
We suggest at least 2.4m x 2.8m. That gives you space to walk around the bed and open drawers or a wardrobe. It's our own guidance rather than Silentnight's, so if your room is a touch under, think about which side of the bed can sit against a wall.
How much wider is the UK small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is the whole point of the size: a teenager or adult who has outgrown a single gains real room to spread out without giving up much floor space.
What bedding fits the small double version of this mattress?
You'll need small double (4ft) fitted sheets, and because this mattress is 31cm deep with a pillow top, deep-fitted versions are the safer buy. A standard double duvet works well on a small double, with a little overhang on each side that most sleepers rather like.
Where can I buy the Memory Cool 2000 in a UK small double?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so it's worth checking back if you're not buying straight away. Availability in the UK small double can differ from the more common UK double and UK king, so a specific size search pays off.
