Layer Details
- Memory Cool™. A graphite-infused memory foam that moulds to your body to relieve pressure, which means less pushback at your hips and shoulders. The graphite actively transfers heat away from you, and Silentnight claims it creates a sleep environment 15% cooler than standard memory foam.
- Mirapocket® springs. 1000 Mirapocket® springs, each held in its own individual pocket so they respond to every movement independently. In practice that means zoned support where you need it and less of the whole-bed wobble you get with open-coil mattresses.

- The classic shared size: At 135 x 190cm it's the long-established couples' standard, wide enough for two without swallowing an average UK bedroom.
- Pocket springs matter more when you share: The 1000 Mirapocket springs respond individually, which means a partner turning over at 3am is less likely to wake you.
- Two warm bodies, cooler foam: Couples generate more heat than solo sleepers, so the graphite-infused Memory Cool layer drawing warmth away is genuinely useful at this size.
- Fits rooms a UK king would crowd: We suggest at least 2.6m x 2.8m, which leaves space for bedside tables on both sides in most master bedrooms.
- Easy to dress and easy to move: Double bedding is stocked everywhere at every price, and the 135cm width copes better with tight landings and turning stairs than larger sizes.
This size suits you if...
You share the bed every night and want the traditional couples' size rather than the extra spread of a UK king, or you sleep alone and like room to stretch out, perhaps with a dog or cat claiming a corner. It also makes sense for a guest room that hosts visiting couples, since the Medium/Firm feel suits most back and combination sleepers without dividing opinion too sharply.
Consider another size if...
You and your partner both sleep hot or move about a lot, and 67.5cm each for two people sharing feels tight. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, needing at least 2.7m x 2.9m of room.

Is the Silentnight Memory Cool 1000 double big enough for a couple?
For most couples, yes. The UK double gives you 67.5cm each for two people sharing, and the 1000 individual pocket springs limit the disturbance you feel when a partner moves. If either of you is broad-shouldered or a restless sleeper, the UK king, 15cm wider, is the more comfortable long-term choice.
What room size do I need for the Memory Cool 1000 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides plus bedside tables, which is where the UK double beats a UK king in a typical UK bedroom: the extra width of a UK king often costs you exactly that.
Should I get the Memory Cool 1000 in a double or a king?
Go with the UK double if your room is close to our 2.6m x 2.8m minimum or you want bedside tables on both sides without squeezing past the bed. Choose the UK king, which is 15cm wider and 10cm longer, if you share every night and have at least 2.7m x 2.9m to work with.
Will a double Memory Cool 1000 fit up narrow stairs?
The UK double is 135 x 190cm and 29cm deep, which is more manageable on turning stairs in older terraces or a tight new build landing than a UK king or UK super king. Measure your tightest turn before ordering, since a hybrid with pocket springs won't fold the way an all-foam roll-up might.
Is a double Memory Cool 1000 good for a guest room?
It's a sensible guest room choice. A UK double accommodates visiting couples as well as solo guests, and the Medium/Firm feel is a safe middle ground for people whose preferences you don't know. The main caveat: lightweight side sleepers may find it slightly firm at the shoulder, though for occasional stays that matters less.
