Layer Details
- Cover. A knitted micro quilted cover, which means the top surface has a soft, slightly cushioned texture stitched into it. It adds a touch of surface comfort without a separate pillow top.
- Fillings. 100% polyester fibre fillings sit between you and the springs. These give a simple, breathable comfort layer, though they won't contour to your body the way memory foam would.
- Springs. 1000 individual pocket springs form the support core, part of Silentnight's Mirapocket system. Each spring is sewn into its own fabric pocket, so it responds to pressure independently and reduces the ripple effect when someone else moves.

- Space beats motion transfer: The 1000 pocket springs already limit ripple from a fidgety partner, and at 90cm each for two people sharing, movement often simply happens too far away to notice.
- Room for night-time visitors: If a child pads in at 3am, or the dog treats the bed as routine, a 180cm width means everyone still gets a workable share.
- 30cm wider than a UK king: The UK super king is 30cm wider than the UK King and the same length, a difference you feel every night if you currently share a smaller bed.
- A big bed at a modest spec: The simple polyester fibre fillings keep this an affordable route to a super king, though the feel is springy rather than plush.
- Fills a large master properly: In a period property or generously sized main bedroom, a UK king can look lost; a 6ft x 6ft 6in bed suits the proportions.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, you have a genuinely restless partner and distance matters more to you than fancy fillings, or children and pets regularly join you and a UK king no longer stretches far enough. Your room comfortably clears our suggested 3m x 2.9m minimum.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you'd struggle to get a 180cm wide mattress up your stairs. We'd recommend the UK king instead, which needs a room of at least 2.7m x 2.9m.

How big is the Silentnight Pocket Essentials 1000 super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That works out at 90cm each for two people sharing, the widest per-person space of any standard UK size, and it's the same length as a UK king with an extra 30cm of width.
What room size do I need for this mattress in a UK super king?
We suggest at least 3m x 2.9m, and that's our guidance rather than Silentnight's. Anything tighter and you'll struggle to open wardrobe doors or walk round the bed. In a loft conversion, check the ceiling slope too, as it often decides which wall the bed can sit against.
Is the super king a good choice for a restless partner?
Yes, arguably the best one. The 1000 pocket springs respond to each sleeper separately, which reduces motion transfer, but 90cm each for two people sharing does most of the work. On a budget mattress like this, extra distance is more effective than extra fillings would be.
Will a super king Pocket Essentials 1000 get up my stairs?
This is the size where staircases bite. A 180cm wide sprung mattress can't be rolled or folded, so measure your stairwell, any landing turns and the bedroom door swing before ordering. This model isn't sold as zip and link halves, so it goes up in one piece.
Is this mattress big enough to share with children or pets?
It's the size we'd point families towards. At 180cm wide, a child wandering in at night, or a large dog with established habits, doesn't force anyone to the edge. The independent pocket springs also mean their fidgeting is less likely to travel across to you.
