Layer Details
- Memory Cool™. A graphite-infused memory foam that moulds to your body, relieving pressure and absorbing energy as you move. The graphite actively transfers heat away from you, which Silentnight says creates a sleep environment 15% cooler than standard memory foam.
- Mirapocket® springs. 2000 Mirapocket springs sit in individual pockets, each responding to your movement independently. In practice that means zoned support where you need it and less motion transfer across the bed.
Layer details from silentnight.co.uk product page, September 2026.
- 90cm of space each: Two sharers get 90cm each, so you can spread out fully without either of you drifting into the other's half of the graphite-infused foam.
- Distance plus motion isolation: The 2000 Mirapocket springs respond independently, and across 180cm of width a fidgeting partner's movement rarely reaches your side at all.
- Room for night-time visitors: When a child or a large dog appears at 3am, a super king absorbs the extra body without everyone waking up cramped.
- Cooler across a bigger bed: The graphite layer that Silentnight says runs 15% cooler than standard memory foam matters more here, where two warm sleepers share one surface.
- The right scale for larger rooms: In a big master bedroom a UK king can look undersized; at 6ft x 6ft 6in this fills the space properly.
This size suits you if...
You share every night and want the maximum sleeping space stocked as standard in the UK, your partner is restless and you have decided distance is the real fix, or children and pets regularly join you and a UK king has started to feel crowded. Your bedroom should measure at least 3m x 2.9m, and around 3.5m x 3.2m will feel more comfortable.
Consider another size if...
Your room is under 3m x 2.9m, or you would rather spend the difference on bedding and furniture. We'd recommend the UK king instead: it is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is a super king too big for a normal bedroom?
Often, yes. We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m before the room feels balanced rather than dominated by the bed. Measure with wardrobes and door swing in mind, and check any landing turns. If the numbers are tight, the UK king needs at least 2.7m x 2.9m.
Is the Memory Cool 2000 in a super king good for restless couples?
It is a strong pairing. The 2000 Mirapocket springs sit in individual pockets, so movement on one side is absorbed rather than passed across the bed, and 90cm each of width adds physical distance on top. Between the two, a partner who turns frequently becomes far easier to sleep through.
Will a super king Memory Cool 2000 fit if children climb in at night?
This is the size for it. At 6ft x 6ft 6in there is room for a small visitor without anyone hanging off the edge, and the pocket springs keep their wriggling from travelling to the far side. A large dog at the foot of the bed is absorbed just as easily.
How much wider is a super king than a king for the Memory Cool 2000?
The UK super king is 30cm wider than the UK king, and the two are the same length. That extra width is what separates a comfortable shared bed from one where two people barely notice each other, which is the whole point of sizing up with this mattress.
