Layer Details
- Sleep surface. A naturally hypoallergenic fabric that feels soft against the skin. A gentle starting point for sensitive or allergy-prone sleepers.
- Airloft™ comfort layer. A foam alternative made from lightweight, open non-woven fibres, which the brand says is 18x more breathable. It mimics the feel of countless tiny springs, gently contouring to your body and spreading your weight evenly.
- 1000 Mini springs. A layer of 1,000 mini springs that respond to even slight movements, which means the surface adjusts as you shift in the night. They also add airflow through the middle of the mattress.
- Comfort Breathe®. Fibres described as 15x more breathable than standard memory foam. They promote airflow and help regulate temperature, a real plus if you tend to overheat.
- 600 Mirapocket spring unit. 600 pocket springs held in individual fabric pockets, each responding independently to your body. That gives you zoned support and better spinal alignment, and less disturbance from a restless partner.
- Protective layer. Disperses pressure from the spring unit across the mattress. In practice, this helps the mattress keep its feel for longer.
- Durable case. A soft but hard-wearing outer case designed to keep the mattress comfortable for years.
Layer details from silentnight.co.uk product page, September 2026.
- Real personal space: The UK king is 15cm wider than the UK double, which means you each get 75cm rather than negotiating the middle of the bed.
- Less disturbance across the width: The 600 Mirapocket springs respond independently, so an early alarm on one side is far less noticeable when there's 150cm between you.
- Extra length for taller sleepers: At 200cm it's 10cm longer than the UK double, a genuine relief if either of you is approaching six foot.
- Breathability across a bigger surface: The foam-free Airloft build lets air move through the whole 150cm width, useful when two warm bodies share one mattress.
- The medium/soft feel, shared: Its gentle, giving surface suits side-sleeping couples, although anyone needing firm support may prefer a different model rather than a different size.
This size suits you if...
You share the bed every night and have started to feel the edges of a double, you or your partner is tall enough that 190cm beds leave feet at the end, or one of you gets up hours before the other and you want space and springs working together to keep the peace.
Consider another size if...
Your bedroom falls under our suggested minimum of 2.7m x 2.9m for a UK king. If space is tight, we'd recommend the UK double instead, which is 15cm narrower and 10cm shorter, needing a room of at least 2.6m x 2.8m.

Is the UK king Comfort Breathe Plus 1600 big enough for a couple?
Comfortably, for most. At 150 x 200cm you get 75cm each for two people sharing, a noticeable step up from a double. Combined with the 600 Mirapocket unit, where each spring moves independently, it gives couples both physical space and less transferred movement. Larger couples who want more still could consider the UK super king.
Will a UK king fit in 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 deceptive: once fitted wardrobes go in, measure the floor that's actually left before committing. If it's tight, the UK double needs at least 2.6m x 2.8m.
Is the UK king long enough for someone over six foot?
Yes, and length is often the real reason taller sleepers upgrade. The UK king is 200cm long, 10cm more than the UK double, so a sleeper around six foot no longer has feet hanging off the end. If height is your only issue, the extra length matters more than the extra width.
Should I choose the UK king or the UK super king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length, so the choice is purely about width and room size. We suggest at least 3m x 2.9m for the UK super king. If your room clears that and you both spread out, size up; otherwise the UK king suits most couples.
Does the UK king reduce partner disturbance?
It helps in two ways. The extra width means movement happens further from you, and the pocket springs sit in individual fabric pockets that respond to the person moving rather than the whole bed. If one of you leaves hours before the other, that combination makes early starts less likely to wake the late sleeper.
