Layer Details
- ActiveBreathe layer. This comfort layer feels like memory foam but is ten times more breathable, which means contouring comfort without the overheating foam is known for. If you tend to sleep warm, this is the feature to pay attention to.
- Mirapocket® spring system. Silentnight's Mirapocket® system uses 800 pocket springs in the king size. Each spring moves independently, so the mattress responds to your shape and reduces the ripple effect when a partner shifts position.
- Eternity layer. The base Eternity layer gives the mattress extra stability and long lasting resilience. In practice, that means the firm feel should hold up rather than softening quickly.

- 75cm each for two sharers: Two people get 75cm of width apiece, which means you can both stretch out rather than negotiating a shared strip in the middle.
- Less disturbance from a restless partner: The Mirapocket® springs, 800 of them in the king size, move independently, so an early riser slipping out is less likely to wake the person still asleep.
- 200cm of length for taller sleepers: At 6ft 6in long, the UK king removes the feet-off-the-end problem that anyone approaching six foot knows from a standard double.
- Firm support across a wider surface: The firm feel stays consistent edge to edge, useful if one of you sleeps near the side or needs stable support getting in and out.
- Cooler sharing for two: Two bodies generate more heat than one, and the ActiveBreathe comfort layer is designed to let that warmth escape rather than trap it in foam.
This size suits you if...
You share the bed every night and a double has started to feel cramped, particularly if one of you is tall enough to appreciate the extra 10cm of length over a UK double. It also suits couples on different schedules, since the independent springs soften the disturbance of one partner leaving hours before the other, and it fits a room of at least 2.7m x 2.9m.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you want even more sprawl than 75cm each. For tighter rooms we'd recommend the UK double instead; for maximum space, the UK super king is 30cm wider and needs at least 3m x 2.9m.

Is the Silentnight Revitalise Refresh 800 in a UK king good for couples?
Yes, provided you both like a firm feel. You get 75cm of width each, and the Mirapocket® springs respond to each sleeper separately, which reduces the ripple when a partner turns over or gets up early. Lightweight side sleepers may find the firmness a little unyielding, so factor that in before sizing up.
Will a UK king Silentnight Revitalise Refresh 800 fit in my bedroom?
The mattress is 150 x 200cm, and we suggest a room of at least 2.7m x 2.9m so you can walk round both sides and open drawers comfortably. New build master bedrooms often shrink once fitted wardrobes go in, so measure the usable floor space rather than the room on the plan.
Should I choose the UK king or the UK double in this mattress?
The UK king is 15cm wider and 10cm longer than the UK double, a difference you feel every night when sharing. On a firm mattress like this you won't roll towards each other much, so the extra width goes further. Choose the UK double only if your room is under 2.7m x 2.9m.
Is the UK king Silentnight Revitalise Refresh 800 long enough for tall sleepers?
At 200cm, or 6ft 6in, it suits most people comfortably, including anyone approaching six foot who finds their feet reaching the end of a 190cm double. If one of you is well over six foot and you have the room, the UK super king offers the same length with 30cm more width.
