Mirapocket pocket spring system
A zoned Mirapocket spring system that Silentnight says supports you both and prevents roll-together, so you each stay comfortably on your own side.

Key benefits
- Room to spread out: Each sleeper gets 90cm of width, which means you can turn over or sprawl a little without ending up on your partner's side.
- More space than a UK king: The UK super king gives 15cm more each than the UK king, and that extra width matters most when one of you tosses and turns.
- Two feels on a wide base: One half is softer and one firmer, so on a 6ft bed you each get your preferred feel across a full 90cm of your own.
- Space for a small visitor: When a child arrives at 3am or the dog settles at your feet, the UK super king leaves both adults a usable share of the mattress.
- Fills a large room properly: In a big master bedroom or a period property with high ceilings, a UK super king looks in proportion where a UK king can seem a little lost.
This size suits you if...
You share with a restless partner and want genuine distance between you, children or a dog regularly join you overnight, or your bedroom is at least 3m x 2.9m and a smaller bed would look undersized in it.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How much space does each person get on the Silentnight Yours & Mine UltraGel super king?
The UK super king gives 90cm each for two people sharing. That's 15cm more each than the UK king and 22.5cm more each than the UK double. If one of you is a restless sleeper, that extra distance between you tends to matter more than any comfort layer.
What size bedroom do I need for a UK super king Yours & Mine mattress?
We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m feels more comfortable. In a loft conversion, the sloping ceiling usually decides which wall the bed goes against, so measure the full-height floor space rather than the whole room.
Is the Yours & Mine super king big enough for us plus the kids or the dog?
It's the most space this mattress comes in, and the 180cm width gives everyone a better share when a child or dog joins you. A large dog that sleeps on the bed every night will still take up a fair amount of room, so a UK super king is easier, though not limitless.
Should I get the Silentnight Yours & Mine in a UK king or a UK super king?
Both are 200cm long, so the difference is width: the UK super king is 30cm wider. Choose the UK super king if you're disturbed by a partner's movement or regularly share with children. If your room is under 3m x 2.9m, the UK king, which needs at least 2.7m x 2.9m, is the more sensible fit.
What bedding fits a Silentnight Yours & Mine super king mattress?
You'll need UK super king sheets, and a 260 x 220cm duvet fits this size. The mattress is 33cm deep, so check that fitted sheets have deep enough pockets. Super king bedding costs more than smaller sizes, so factor that in alongside the mattress itself.
