Key benefits
- 90cm of your own: Silentnight says its Mirapocket springs adapt to your body, and with 90cm each for two sharing, a partner's restless turning happens well away from your side.
- 15cm more each than a king: The UK super king is 30cm wider than the UK king at the same length, which means 15cm more each, enough to notice on a fidgety night.
- Space for the extras: When a child wanders in or a large dog sleeps on the bed as routine, 180cm of width means someone squeezing in no longer pushes anyone to the edge.
- Airflow for a busier bed: More bodies in one bed means more warmth, so the airy fibres Silentnight uses to help air flow should suit a family-sized sleeping surface.
- In scale with a big room: In a period property or a large master bedroom, a 6ft wide mattress at 36cm deep looks in proportion where a UK king can look a little lost.
This size suits you if...
You share the bed every night with a genuinely restless partner and want real distance between you, or your children and dogs regularly end up in bed with you and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or your stairs and landing are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How big a room do I need for a Silentnight Breatheasy 1000 super king?
We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m tends to feel comfortable rather than tight. In a loft conversion, measure where the ceiling slopes down first, because the sloping wall usually decides where a 6ft wide bed can go. Check the door swing clears the corner as well.
Is a super king worth it over a king if my partner is restless?
For a genuinely restless partner, usually yes. The UK super king gives 90cm each against 75cm each on the UK king, so 15cm more of your own space. Silentnight says its Mirapocket springs adapt to each body, but physical distance is what keeps a kicked leg or a flung arm off your side.
Will a super king mattress fit two adults and a child?
It's the widest standard UK size, at 180cm. With a small child in the middle, each adult keeps more room than on a UK king, which is 150cm wide. Expect it to feel full once children grow or a large dog joins in too, so think about how your household might change.
What bedding fits a super king Breatheasy 1000?
You need super king sheets and a 260 x 220cm duvet. At 36cm deep, look for fitted sheets with deep pockets, as shallow ones may not tuck under. Super king bedding also costs more than smaller sizes, so factor that in if you're replacing everything at the same time.
Will a 180 x 200cm mattress get up my stairs?
A mattress this wide and 36cm deep is bulky to manoeuvre, and tight landing turns cause the most trouble. Measure every doorway, the stairwell and any turn on the landing before ordering, then compare the retailers listed on this page once you're sure the UK super king will make it to the bedroom.
