- The classic couples' footprint: At 135 x 190cm, or 4ft 6in x 6ft 3in, this is the size most UK couples share, and most UK bedrooms are built around.
- Room left over for furniture: Allow at least 2.6m x 2.8m and you'll still fit bedside tables on both sides, plus a wardrobe, where a UK king would crowd the walls.
- 67.5cm each when sharing: Two people get 67.5cm each for two people sharing, workable for most couples, although restless sleepers may feel each other's movements on foam.
- A light lift on the stairs: An all-foam double is easier to flex round a turning staircase in an older terrace or a tight new build landing than a sprung mattress of the same size.
- Cheap and easy to dress: Double sheets and 200 x 200cm duvets are sold everywhere at every price point, useful if you're furnishing a whole home and the budget is already stretched.
This size suits you if...
You share the bed every night and want the traditional couples' size without giving the whole room over to the mattress, you're kitting out a first flat or a guest room where visiting couples will stay, or you sleep alone but like space to spread out, perhaps with a dog or cat claiming a corner.
Consider another size if...
You and your partner both like room to sprawl, or one of you is a restless sleeper. On a foam mattress that closeness is noticeable, so if your room allows at least 2.7m x 2.9m, we'd recommend the UK king instead.

Is the Silentnight Comfortable Foam Sleep Mattress in a UK double good for couples?
Yes, for most. The UK double is the long standing shared size, giving 67.5cm each for two people sharing. Foam also transfers less movement noise than springs, which helps if you go to bed at different times. Larger couples, or those who spread out, may prefer the UK king, which is 15cm wider and 10cm longer.
Will a UK double Silentnight foam mattress fit my bedroom?
The mattress measures 135 x 190cm, and we suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves space to walk round the bed and open drawers. If you want bedside tables on both sides, measure the wall the bed sits against before committing.
Is the double version of this mattress easy to get upstairs?
Silentnight doesn't publish a weight for this size, but all-foam doubles are generally lighter and more forgiving to manoeuvre than sprung equivalents, which helps on the turning stairs of older terraces or a narrow new build landing. A 135cm width still needs two people to carry comfortably, so plan for a second pair of hands.
Should I get this mattress in a UK double or a UK single for a spare room?
If the room mainly hosts visiting couples, the UK double is the safer buy: it's 45cm wider than the UK single at the same length, so two guests can share without complaint. If the room is small, the UK single needs only 2.1m x 2.8m of floor space, against our suggested 2.6m x 2.8m for the double.
How does the UK double compare with the small double for this mattress?
The UK double is 15cm wider than the UK small double, and the two are the same length. For a couple, that extra width matters on foam, where you tend to stay in your own dip rather than rolling together. The UK small double suits a solo sleeper in a compact room, needing at least 2.4m x 2.8m.
