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.

- Proper space for two: At 150cm across, the UK king is 15cm wider than the UK double, which means each of you gets a genuine half of the bed.
- Less partner disturbance at this width: The 2000 individually pocketed Mirapocket springs absorb movement locally, so an early riser slipping out at six can leave the other side largely undisturbed.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, a real difference if one of you is approaching six foot and used to feet hanging over the edge.
- Cooler when sharing: Two bodies raise the temperature under a duvet, so the graphite-infused Memory Cool foam, which Silentnight says runs 15% cooler than standard memory foam, matters more at this size.
- Cushioning across the whole surface: The pillow top and slow-moulding foam cradle each sleeper separately, so a side sleeper and a back sleeper can share without compromising.
This size suits you if...
You share the bed every night and a double has started to feel like a negotiation, one of you keeps different hours to the other and movement wakes you, or a taller partner needs the extra 10cm of length a UK king brings. It also suits couples whose dog has quietly claimed a corner and shows no sign of giving it back.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. We'd recommend the UK double of this mattress instead, where we suggest at least 2.6m x 2.8m.

Is the Silentnight Memory Cool 2000 in a UK king big enough for two adults?
Yes, comfortably for most couples. The UK king measures 150 x 200cm, which works out at 75cm each for two people sharing. Combined with the 2000 pocketed springs limiting motion transfer, it gives each of you your own settled patch of bed. If you want still more room, the UK super king is 30cm wider.
Will a UK king Memory Cool 2000 fit in my bedroom?
We suggest allowing at least 2.7m x 2.9m for a UK king, which leaves room to walk round the bed and open drawers. Measure with wardrobes and radiators in mind: newer master bedrooms often feel smaller than the floor plan suggests once furniture is in. If it's tight, the UK double needs at least 2.6m x 2.8m.
Is the UK king long enough for a tall sleeper?
At 200cm, the UK king is 10cm longer than the UK double, which is often the difference between feet on the mattress and feet in mid-air for anyone around six foot. The pillow top runs edge to edge, so you get the same cushioned feel right to the foot of the bed.
Does the king size help if my partner gets up earlier than me?
It helps on two fronts. The width means you're rarely sleeping close enough to feel every shift, and the 2000 Mirapocket springs respond to movement individually, so one side compressing doesn't ripple across to the other. Slow-recovery memory foam also absorbs motion rather than bouncing it back.
How does the UK king compare with the UK super king in this mattress?
The UK king is 30cm narrower than the UK super king, and the two are the same length. The UK super king needs a bigger room: we suggest at least 3m x 2.9m for it, against 2.7m x 2.9m for the UK king. For most couples the UK king is the more practical fit.
