Key benefits
- Fits most UK bedrooms: At 135 x 190cm it leaves space for a wardrobe and drawers where a UK king would start to crowd the room.
- Room for two: You get 67.5cm each for two people sharing, which is comfortable for most couples, although broad shouldered pairs may feel it.
- Boxed delivery suits awkward access: Rolled and compressed, it can be carried up the turning stairs of an older terrace or across a tight new build landing without a struggle.
- Pocket springs help light sleepers sharing: The 1000 pocket springs move independently, which means less disturbance when your partner turns over in the night.
- Cheapest size to dress: Double sheets and a 200 x 200cm double duvet are stocked everywhere, useful if you're kitting out a whole home at once.
This size suits you if...
You share the bed every night and want the traditional couples' size in a room where a UK king would dominate, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since a UK double is what most guests expect to find.
Consider another size if...
Your room comfortably exceeds 2.7m x 2.9m and you both like space, or one of you is tall. The Mirapocket 1000 in a UK king is 15cm wider and 10cm longer, and we'd recommend it instead.

FAQ's
Will a UK double Mirapocket 1000 fit in my bedroom?
We suggest allowing at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That leaves room to walk round the bed and open drawers. If you want bedside tables on both sides, sketch the layout first: the mattress itself is 135cm wide, so the tables add to that.
Is the double big enough for two on this mattress?
You get 67.5cm each for two people sharing, and the pocket springs reduce the ripple you feel when a partner moves, which matters more at this width than on a bigger bed. Most couples find it fine. If either of you sprawls, the UK king version of this mattress adds 15cm of width.
Can I get the boxed double up narrow stairs?
More easily than a conventional double, yes. The Mirapocket 1000 arrives rolled and compressed in a box, so turning stairs in older terraces and tight new build landings are far less of a problem. Unbox it in the bedroom itself, because once it expands you won't be moving it anywhere easily.
Is the UK double Mirapocket 1000 a good guest room choice?
It's a natural fit. A UK double is the size visiting couples expect, and at 135 x 190cm it usually leaves enough floor space in a second bedroom for a wardrobe and a chest of drawers. Double bedding is cheap and easy to find too, handy for a room used a few weeks a year.
Should I choose this mattress in a UK double or a UK single?
For anyone sharing, the UK double. For a solo sleeper it depends on the room: the UK double is 45cm wider than the UK single, and both are the same length, so you gain width, never legroom. In a small room we suggest at least 2.1m x 2.8m for the UK single.
