Key benefits

Key Benefits of the Silentnight Mirapocket 1200 Memory Double Mattress

  • Independent springs where they count: Pocket springs move on their own, which means your partner turning over at 3am registers far less on your side of a shared 135cm surface.
  • A width most rooms can take: At 4ft 6in x 6ft 3in, this size leaves space for a wardrobe and drawers in a typical UK bedroom, where a UK king often would not.
  • Room for bedside tables both sides: Allow at least 2.6m x 2.8m and you should still fit a table on each side, which makes daily life around the bed noticeably easier.
  • A sensible guest room choice: Visiting couples expect a double, and the memory foam surface softens the initial feel for guests who arrive used to all sorts of mattresses.
  • Easier to get upstairs: A 135cm-wide mattress turns the stairs of an older terrace or a tight new build landing more readily than the wider sizes in this range.

Who should buy the Silentnight Mirapocket 1200 Memory Double Mattress?

This size suits you if...

You share the bed every night and want the classic couples' size without giving up floor space, or you sleep alone and like room to stretch, perhaps with a dog or cat claiming a corner. It also suits a guest room that needs to sleep visiting couples comfortably. Your room should measure at least 2.6m x 2.8m, our suggested minimum for a UK double.

Consider another size if...

You and your partner both like space, since 67.5cm each for two people sharing is snug for restless sleepers. If your room allows at least 2.7m x 2.9m, we'd recommend the UK king instead.

FAQ's

Frequently Asked Questions About the UK Double

Is the Silentnight Mirapocket 1200 Memory in a UK double big enough for a couple?

It gives 67.5cm each for two people sharing, which most couples find workable rather than generous. The pocket springs help here: each spring compresses independently, so movement on one side carries less across a shared surface. If either of you sleeps restlessly or spreads out, the UK king is the more comfortable long-term choice.

What room size do I need for the UK double version of this mattress?

We suggest at least 2.6m x 2.8m for a UK double. That allows walking space around the bed and, in most layouts, a bedside table on each side. If you're furnishing a second bedroom or first flat, this footprint usually still leaves room for a wardrobe and a chest of drawers.

Will this mattress fit up a narrow staircase in a UK double?

At 135 x 190cm it's the more manageable of the shared sizes, and a double will turn a tight landing or terrace staircase more easily than a UK king or UK super king. Silentnight doesn't publish handling guidance for this model, so measure your tightest turn before ordering if access is awkward.

Should I get the Silentnight Mirapocket 1200 in a UK double or a UK king?

The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is a typical size or you want space around the bed; go for the UK king if you both value sleeping room and your bedroom measures at least 2.7m x 2.9m.
