Layer Details
- 90cm each, every night: Two people sharing get 90cm apiece, which means a partner who turns over constantly is happening at a distance rather than against your back.
- Firm support across the full width: The Miracoil system runs zoned support through the whole 180cm, so someone sleeping near the edge gets the same solid feel as someone in the middle.
- Space for company: When a child wanders in at 3am or the dog claims the foot of the bed, a 6ft width means nobody ends up clinging to the edge.
- Same length as a UK king: At 200cm long it matches the UK king, so taller sleepers lose nothing by having the extra width.
- Distance beats cushioning: This is a firm mattress rather than a plush one, but at this width sheer separation does more to protect your sleep than any comfort layer would.
This size suits you if...
You share the bed every night and want the most space you can buy, your children or pets treat your bed as their own and you'd rather plan for that than fight it, or one of you is a genuinely restless sleeper. Your bedroom should measure at least 3m x 2.9m, and ideally more, so the bed doesn't dominate the room.
Consider another size if...
Your bedroom is under our suggested minimum of 3m x 2.9m, or you sleep alone. We'd recommend the UK king instead: it's 30cm narrower but the same length, and needs a smaller room, at least 2.7m x 2.9m.

How much space do two people get on the Silentnight Special Sleep super king?
The UK super king measures 180 x 200cm, or 6ft x 6ft 6in, which gives two people sharing 90cm each. That's the same width per person as a UK single, so you can both stretch out without negotiating territory in the night.
Is the Silentnight Special Sleep super king worth it over the UK king?
The UK super king is 30cm wider than the UK king and exactly the same length, so the decision comes down to width and room size. If a restless partner or visiting children are the problem, the extra 30cm helps more than any change of mattress would. Allow at least 3m x 2.9m for the super king.
Will I feel my partner move on a super king Miracoil mattress?
The Miracoil system uses a connected spring unit rather than individual pocket springs, so it passes on more movement than pocket-sprung rivals. In the UK super king, though, 90cm each puts real distance between you, and that gap does a lot of the isolating work on its own.
Is the Silentnight Special Sleep super king good for families sharing the bed?
It's a sensible pick if children or a dog regularly join you. The 180cm width absorbs an extra small body without pushing anyone to the edge, and the firm, zoned support stays stable under uneven weight. Lightweight side sleepers in the family may find the firmness a little unyielding, so bear that in mind.
What should I check before buying a UK super king?
Measure the room first: we suggest at least 3m x 2.9m for a UK super king. Then check the route in, since door swings and tight landing turns can be awkward with a mattress this size. Bedding is a separate line on the budget too, as super king sheets and duvets cost more. Compare the retailers listed on this page for current prices.
