- 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.

- Room to share without crowding the room: At 135 x 190cm it fits comfortably in most UK bedrooms, so you can still open the wardrobe and keep a chest of drawers.
- 67.5cm each for two sharing: Each of you gets 67.5cm of that cushioned pillow top surface, enough for most couples to settle without elbowing.
- Springs that keep the peace in a shared bed: The 2000 Mirapocket springs respond individually, which means a partner turning over on their side of the double barely reaches yours.
- Cooler comfort where two bodies share the heat: Two sleepers in one bed generate more warmth, so the graphite-infused foam, which Silentnight says sleeps 15% cooler than standard memory foam, matters more in a double.
- Easy to dress and easy to place: Double bedding is stocked everywhere at every price, and a 200 x 200cm double duvet covers it neatly.
This size suits you if...
You share the bed every night and want the classic couples' size that still leaves your bedroom feeling like a room, or you sleep alone and fancy space to stretch out, perhaps with a dog or cat claiming a corner. It also suits a guest room that regularly hosts visiting couples, since the medium feel and pillow top keep most people comfortable.
Consider another size if...
You and your partner both toss and turn, or one of you sleeps hot and wants distance. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and we suggest a room of at least 2.7m x 2.9m for it.

Is the Silentnight Memory Cool 2000 UK double big enough for a couple?
For most couples, yes. You each get 67.5cm of width, and the 2000 Mirapocket springs respond to movement individually, so a restless partner disturbs you less than the modest width might suggest. If either of you is broad-shouldered or a sprawler, the extra space of the UK king is a fair upgrade.
What size room do I need for the Memory Cool 2000 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows bedside tables on both sides and room to walk around the bed, which matters in a shared room where both of you need your own way in and out.
What are the dimensions of the Silentnight Memory Cool 2000 UK double?
It measures 135 x 190cm, which is 4ft 6in x 6ft 3in. That's the long-standing UK standard for two people sharing, and it takes standard double sheets and a 200 x 200cm double duvet, both stocked everywhere at every price.
Should I size up to the UK king for this mattress?
The UK double is 15cm narrower and 10cm shorter than the UK king. If either of you is tall or you both move a lot at night, the UK king is the better buy, provided your room offers at least 2.7m x 2.9m. In a smaller room, the UK double keeps the space usable.
Is the UK double a good choice if I sleep alone?
Yes, and it's a slightly indulgent one. A solo sleeper gets the full 135cm to spread across, with the pillow top cradling you wherever you settle, and there's room left over if a pet insists on their corner. It also makes sense if you're furnishing a first flat and want a bed that works if circumstances change.
