Key benefits
- Made for two in an ordinary room: At 135 x 190cm, this UK double gives couples a shared bed that fits comfortably where a UK king would dominate the floor.
- Springs that suit sharing: The 1000 Mirapocket springs respond to each sleeper separately, which means your partner turning over is less likely to disturb you.
- Room for tables both sides: In a room of around 3m x 3m, the UK double usually leaves space for bedside tables on both sides, something a UK king often sacrifices.
- A practical guest room choice: Its Medium/Firm feel suits a wide range of visitors, and the UK double is the size a visiting couple expects to find.
- Easy to dress cheaply: Standard double sheets and a 200 x 200cm double duvet fit this size, and both are stocked everywhere at every price.
This size suits you if...
You're a couple sharing every night in a typical UK bedroom, you're kitting out a guest room that needs to sleep two visitors comfortably, or you're furnishing a first flat or second bedroom where the bed has to leave room for a wardrobe and drawers. The 135 x 190cm footprint is the long-standing standard for sharing, and this mattress's slightly firmer feel suits most sleepers.
Consider another size if...
You share the bed nightly and want more personal space than 67.5cm each for two people sharing allows. 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.

FAQ's
Is the Silentnight Comfort Pocket Essentials UK double big enough for a couple?
Yes, for most couples. The UK double is 135 x 190cm, giving 67.5cm each for two people sharing, and the 1000 Mirapocket springs limit how much you feel a partner moving. If either of you is tall or sleeps sprawled, the UK king adds 15cm of width and 10cm of length.
What room size do I need for this mattress in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That gives you space to open a wardrobe and fit bedside tables on both sides. This is our own guidance rather than Silentnight's, so measure your room before ordering.
Should I get the Silentnight Comfort Pocket Essentials in a double or a king?
Choose the UK double if your room is on the smaller side or you want cheaper bedding; choose the UK king if you share every night and value personal space, since it's 15cm wider and 10cm longer. For the UK king we suggest a room of at least 2.7m x 2.9m.
Is a UK double a good size for a guest room?
It's the natural choice. A UK double sleeps visiting couples without swallowing a spare room, and this mattress's Medium/Firm feel is a safe middle ground for guests you can't ask about firmness preferences. Lightweight side sleepers may find it slightly firm, but for occasional use that matters less.
