Layer Details
- Memory Foam Comfort Layer. A responsive memory foam that gently moulds to your body's contours, which means it absorbs energy and eases built-up pressure at the hips and shoulders. You'll feel a slight cradling on the surface rather than a deep sink.
- Mirapocket Spring Support System. 1000 individually nested pocket springs (based on the king size, with the count varying pro-rata for other sizes) react independently to your body weight and movement. Silentnight states the zoned support is scientifically proven to help spinal alignment and posture.

- Room for two, space for the room: At 135 x 190cm the UK double leaves enough floor around it for bedside tables on both sides in most bedrooms, which a UK king often doesn't.
- 67.5cm each for two people sharing: That's the established standard couples have slept on for decades, and the independent Mirapocket springs mean one of you turning over disturbs the other less.
- Medium/Firm suits a shared bed: A middle-ground feel is a safe pick when two people with different preferences share, although lightweight side sleepers may find it slightly too solid.
- Easy to dress: Standard double sheets and duvets are stocked everywhere at every price, and the 25cm depth suits ordinary fitted sheets without stretching.
- A sensible guest room size: The UK double comfortably sleeps visiting couples, and the Purotex allergen treatment is a quiet bonus when different guests use the bed.
This size suits you if...
You share the bed most nights and your room is a typical UK size, allow at least 2.6m x 2.8m for this mattress with space to move around it. It also suits you if you're kitting out a guest room that needs to sleep visiting couples, or you sleep alone and want space to spread out without giving a whole room over to the bed.
Consider another size if...
You and your partner both like to sprawl, or one of you is a restless sleeper, and your room measures at least 2.7m x 2.9m. We'd recommend the UK king instead: 15cm wider and 10cm longer.

Is the UK double Pocket Essentials 1000 big enough for a couple?
For most couples, yes. You get 67.5cm each for two people sharing, the long-standing UK standard, and the individually nested Mirapocket springs react to each sleeper separately, so movement transfers less across the bed. If either of you is broad-shouldered or a restless sleeper, the UK king adds 15cm of width and 10cm of length.
What room size do I need for a double Silentnight Pocket Essentials 1000?
We suggest a minimum of 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That leaves walking space on both sides and, in most rooms, enough wall left for bedside tables each side, something a UK king can squeeze out in a typical British bedroom.
How many springs does the UK double version have?
Silentnight counts the 1000 Mirapocket springs on the king size, with the count varying pro-rata for other sizes, so the UK double has proportionally fewer. The brand doesn't publish an exact double figure. In practice the spring density across the surface is the same, so the feel and zoned support don't change with size.
What bedding fits the double Pocket Essentials 1000?
Standard UK double bedding: fitted sheets sized 135 x 190cm and a 200 x 200cm double duvet. At 25cm deep, this mattress sits within the range ordinary fitted sheets are cut for, so you shouldn't need deep-pocket versions. Double bedding is also the most widely stocked size in the UK, at every price point.
Should a couple pick this mattress in a double or a king?
It comes down to your room. The UK double needs at least 2.6m x 2.8m; the UK king is 15cm wider and 10cm longer and needs at least 2.7m x 2.9m. If your bedroom clears the larger figure and you both value space, size up. In a smaller room, the double keeps the bed from dominating.
