Layer Details
- Memory Cool™. A graphite-infused memory foam that moulds to your body to relieve pressure, which means less tossing to find a comfortable position. The graphite actively transfers heat away from you, and Silentnight claims this makes it 15% cooler than standard memory foam.
- Mirapocket® springs. 2000 Mirapocket® springs, each held in its own individual pocket so they respond to every movement independently. In practice that means zoned support for your back and less motion transfer across the bed.

- 75cm each for two sharing: Two people get 75cm of width apiece, which means you can settle into your own side rather than negotiating space all night.
- Distance plus pocket springs: The 2000 individual springs respond to movement separately, and the wider footprint keeps you further from that movement in the first place, so early alarms disturb less.
- 200cm of length: The UK king runs 10cm longer than the UK double, which means anyone approaching six foot stops finding their feet at the edge.
- Cooler surface across a bigger bed: The graphite-infused Memory Cool™ foam draws heat away from your body, and with 75cm each there's more untouched, cooler surface to move onto.
- Room to shift position: The moulding memory foam relieves pressure while the extra width lets you prop pillows or change position without crowding a partner, useful during pregnancy or recovery.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, one of you gets up hours before the other and you'd rather not feel it, or someone in the bed is tall enough that a 190cm mattress leaves their feet hanging. It also suits couples who want more space without the room a UK super king demands.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. In either case we'd recommend the UK double instead, which needs around 2.6m x 2.8m.

Is the Silentnight Memory Cool 2000 in a UK king big enough for a couple?
Yes, for most couples it's the comfortable choice. At 150cm wide it gives two people 75cm each, and the 2000 Mirapocket® springs respond to each sleeper independently, so you feel less of a partner's tossing. If you regularly share with a child or a dog, the UK super king is 30cm wider and worth considering.
Will a UK king Silentnight Memory Cool 2000 fit my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves space to walk round the bed and open drawers. New build master bedrooms can be tighter than they look once wardrobes go in, so measure the usable floor rather than the wall-to-wall figure before committing.
Is the UK king long enough for tall sleepers?
At 200cm, the UK king is 10cm longer than the UK double, and that difference is often the whole point of the upgrade. If one of you is over six foot, the extra length stops feet reaching the end of the mattress. The UK super king is the same length, so sizing up only adds width.
Does a king size help if my partner gets up earlier than me?
It helps in two ways. The 2000 pocket springs move independently, so one side compressing doesn't tilt or bounce the other, and with 75cm of width each there's simply more mattress between you. Neither makes a bed silent, but together they make a 5am alarm far easier to sleep through.
