Key benefits
- The classic shared size: At 135 x 190cm, the UK double gives a couple a proper shared bed without dominating a typical British bedroom.
- Pocket springs matter more at this width: With 67.5cm each for two people sharing, independently moving springs help mask a partner's movement when you're sleeping fairly close.
- Fits rooms a king would crowd: Allow at least 2.6m x 2.8m and you should still have space for wardrobes and a route around the bed.
- Bedding is cheap and everywhere: Double sheets and a 200 x 200cm duvet are stocked at every price point, which keeps the ongoing cost of dressing the bed down.
- Easier to get upstairs: A double is more forgiving on the turning stairs of older terraces and tight new build landings than the wider sizes of this mattress.
This size suits you if...
You share the bed every night and want the standard couples' size that still leaves room for bedside tables on both sides, you sleep alone but like space to stretch out, or perhaps with a pet who claims a corner, or you're furnishing a guest room that needs to handle visiting couples comfortably.
Consider another size if...
You and your partner both want more personal space than 67.5cm each, or one of you is a restless sleeper. 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 Mirapocket 1000 in a UK double good for couples?
It's a sensible pairing. The UK double gives two people 67.5cm each, and the Mirapocket 1000's pocket springs move independently, so a partner shifting position transfers less through the mattress. Lighter movers will notice this less than restless sleepers, but at this width, where you sleep close together, it's a genuine advantage over an open coil design.
Will a UK double Mirapocket 1000 fit my bedroom?
The mattress is 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 usually leaves space for bedside tables on both sides plus a wardrobe. If you're squeezing it into a small second bedroom alongside drawers, measure your walking routes first.
Should I get the Mirapocket 1000 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. If space is tighter, or the bed is for a guest room, the UK double is the safer call.
Is the double Mirapocket 1000 a good guest room mattress?
Yes, with a caveat. A UK double handles visiting couples as well as solo guests, and pocket springs mean two unfamiliar sleepers disturb each other less. The caveat is that Silentnight doesn't publish full firmness or construction details for this model, so check the retailer listing if your guests have specific comfort needs.
Can I get a UK double Mirapocket 1000 up a narrow staircase?
Usually, yes. At 4ft 6in x 6ft 3in, a double is the widest size that tends to manage the turning stairs of older terraces and tight new build landings without drama. Silentnight doesn't publish handling guidance for this model, so measure your tightest turn against the 135cm width before ordering, especially in a first flat.
