- Room to share, sensibly: Two people sharing get 67.5cm of width each, which means comfortable co-sleeping without the footprint of a king dominating the floor.
- Fits most UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which leaves space for a wardrobe and drawers in a typical double bedroom or first flat.
- Bedside tables on both sides: At 135cm wide, most rooms that meet our suggested minimum can still take a table each side, so nobody's phone charges on the floor.
- Easy, affordable bedding: Double sheets and duvets are the most widely stocked in the UK, which keeps dressing the bed cheap if you're kitting out a whole home at once.
- Generous for one: Sleeping solo, you get the full 135cm to yourself, which is ample even when a dog or cat has claimed a corner by morning.
- Works for guests too: A UK double handles visiting couples in a guest room, so the bed does double duty rather than sitting sized for one.
This size suits you if...
You share the bed every night and want the standard couples' size, your bedroom is a typical UK double room around our suggested 2.6m x 2.8m minimum, or you sleep alone and want space to spread out, pet included. It also makes sense if you're furnishing a whole home and need bedding that's cheap and easy to find.
Consider another size if...
You both feel cramped at 67.5cm of width each and your bedroom is generous. We'd recommend the UK super king instead, which is 45cm wider and 10cm longer; allow at least 3m x 2.9m of floor space for it.

Will the Silentnight Just Sleep Calm UK double fit in a typical UK bedroom?
In most cases, yes. The mattress measures 135 x 190cm, and we suggest a room of at least 2.6m x 2.8m so you can walk round the bed and open drawers without shuffling sideways. A room nearer 3m square feels noticeably more relaxed and usually allows bedside tables on both sides.
How much space does each person get on the Just Sleep Calm UK double?
Two people sharing get 67.5cm of width each. That's comfortable for most couples, though if one of you sleeps in a starfish position you'll know about it. Solo sleepers get the full 135cm, which is plenty even with a pet claiming a corner of the bed.
Should I choose the Just Sleep Calm in a UK double or the UK super king?
It mostly comes down to your room. The UK double is 45cm narrower and 10cm shorter than the UK super king, and needs less floor space: we suggest at least 2.6m x 2.8m for the UK double, against at least 3m x 2.9m for the UK super king. If your bedroom comfortably clears the larger figure and you share nightly, the extra width is a genuine upgrade.
Is the UK double of the Just Sleep Calm a good guest room size?
Yes, it's arguably the best all-round guest size. At 135 x 190cm it sleeps visiting couples properly rather than squeezing them into something smaller, and double bedding is cheap and stocked everywhere, which matters for a bed that's only made up a few times a year.
