Key benefits
- 90cm of width each: Two people sharing get 90cm each, enough distance that most disturbances stop before they reach you.
- Pocket springs plus space: The 1000 Mirapocket springs move independently, which means a partner turning over on their side of a 180cm surface barely registers on yours.
- 30cm wider than a UK king: The UK super king is 30cm wider than the UK king and the same length, so you gain sideways room without needing a longer bed frame.
- Room for the whole household: When a child pads in at 3am or the dog claims the foot of the bed, this width absorbs the extra body without anyone perching on an edge.
- Pillow top comfort at full width: The pillow top and Geltex layer run across the whole 180cm surface, so neither sleeper is stuck with a lesser patch.
This size suits you if...
You share the bed every night with a restless partner and want space to do the ignoring rather than relying on the mattress alone, your children or a large dog regularly join you and a UK king has started to feel crowded, or you have a large master bedroom where a smaller bed would look and feel undersized.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest for a UK super king, or bedding costs at this size put you off. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
Is the UK super king Silentnight Mirapocket 1000 good for restless partners?
It's arguably the strongest case for this size. The pocket springs respond to each sleeper individually, and the 90cm of width each person gets adds physical distance on top. A partner who turns constantly is much less of a problem when they're doing it well over an arm's length away.
Should I choose the UK king or the UK super king in this mattress?
The UK super king is 30cm wider than the UK king and they're the same length, so the decision is really about width and room size. If children or pets share regularly, or one of you sleeps lightly, the extra 30cm makes a genuine difference. In a room under 3m wide, the UK king is the sensible call.
How big a bedroom do I need for the Silentnight Mirapocket 1000 in a UK super king?
We suggest a room of at least 3m x 2.9m, and that's a minimum rather than a comfortable fit. Before ordering, check the door swing and any tight landing turns, because a mattress at 180 x 200cm is awkward to manoeuvre even when the room itself is large enough.
Can children share a UK super king with two adults?
More comfortably than any smaller size. At 180cm wide, a small visitor in the middle of the night still leaves both adults a reasonable share, where the same scenario on a UK double gets cramped quickly. It's a common reason parents of young children size up, and it works just as well for a large dog with established habits.
Where can I buy the Silentnight Mirapocket 1000 in a UK super king?
