- Fits the average UK bedroom: At 135cm wide, this double leaves walking space and room for furniture where a UK king can start to dominate.
- Room for bedside tables on both sides: Allow at least 2.6m x 2.8m and most couples can still fit a table each side, which a wider size often rules out.
- Zoned springs across a shared bed: The Miracoil system gives targeted support along the mattress, which means each of you gets support where your weight actually sits.
- Memory foam softens the sharing: The body moulding memory foam layer settles around shoulders and hips, so a partner's slightly different sleeping position matters less.
- Easy to dress and replace: Double sheets and duvets are stocked everywhere at every price, handy if this is a guest room you dress occasionally.
This size suits you if...
You share the bed every night and your room sits around the typical UK bedroom footprint, you're kitting out a guest room that needs to sleep visiting couples comfortably, or you sleep alone and want space to spread out without giving the bed the whole room. With 67.5cm each for two people sharing, it suits couples who don't mind sleeping fairly close.
Consider another size if...
You and your partner both need real space, or one of you is tall enough to find 190cm tight. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m and we'd recommend it instead.

Is the Silentnight Comfort Miracoil Memory in a UK double big enough for a couple?
It sleeps two, with 67.5cm each for two people sharing. The zoned Miracoil springs and memory foam top help each sleeper feel supported, but that width means you'll sleep fairly close together. Couples who value personal space, or anyone over about six foot, would feel the benefit of the UK king.
What room size do I need for this mattress in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That smaller minimum still leaves room to walk around the bed and, in most layouts, fit a bedside table on each side. This is our guidance rather than Silentnight's, so measure your own room before ordering.
Should I get this Silentnight mattress in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king. If your room meets our suggested 2.7m x 2.9m for the UK king and you share every night, the extra width is usually worth having. In a smaller room, or a guest room used occasionally, the UK double is the more sensible fit.
Will a UK double fit up the stairs in an older house?
At 135 x 190cm it's a more manageable carry than the UK king or UK super king, which helps on the turning staircases of older terraces and tight new build landings. Silentnight doesn't publish handling guidance for this model, so check access measurements and ask the retailer about delivery to the room before you buy.
Is the UK double a good choice for a guest room?
Yes, it's arguably the best size for one. It sleeps visiting couples where a UK single can't, without swallowing a spare room the way a UK king might, and double bedding is the cheapest and easiest to find. The memory foam and spring combination should suit a range of guests without you knowing their preferences.
