Key benefits
- Room for a restless partner: You each get 90cm of width, which means one person turning over on the cushioned pillow top is much less likely to disturb the other.
- A share for everyone at 3am: When a child climbs in after a bad dream, the 180cm width means both adults keep a usable strip of mattress rather than clinging to the edges.
- A step up from the UK king: It is 30cm wider than the UK king and the same length, giving each sleeper 15cm more without needing a longer room.
- Scaled for a large master bedroom: In a generous master or a high-ceilinged period bedroom, a 6ft x 6ft 6in bed fills the space in proportion instead of floating in the middle.
- Cooler with more bodies in the bed: The CoolEase cover is designed to draw heat away quickly, which helps when a child or dog adds extra warmth to a shared bed.
This size suits you if...
You share with a partner who tosses and turns all night, children or a large dog regularly end up in your bed, or your bedroom is at least 3m x 2.9m and you want a soft, cushioned surface with space to spread out.
Consider another size if...
Your bedroom is under 3m x 2.9m, or a 180cm wide mattress won't clear your stairs and landing. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will a Silentnight Reflex 2200 super king fit in my bedroom?
We suggest a room of at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling comfortable once you add bedside tables on both sides. Measure the door swing as well, as a 180cm wide bed can stop a door opening fully on some layouts.
Is a super king worth it over a king for a restless partner?
For a partner who moves a lot, yes. The UK super king gives 90cm each against 75cm in the UK king, so 15cm more per person at the same length. The plush pillow top softens movement a little, but that extra distance does more to keep you asleep.
Is a UK super king big enough for two adults and a child?
For occasional night visits, mostly yes. Two adults on their own get 90cm each, so a small child squeezes in without anyone ending up on the floor edge. If a child sleeps with you most nights, or a large dog joins too, expect the bed to feel full.
What size bedding do I need for the Reflex 2200 super king?
You need UK super king fitted sheets with deep enough pockets for a 33cm mattress, as standard pockets may slip off the pillow top corners. A 260 x 220cm duvet fits. Super king bedding is pricier than UK king bedding, so factor in a spare set.
Will a super king mattress fit in a loft conversion?
Check access and headroom first. Getting a 180cm wide mattress round a tight landing turn is the usual sticking point, so measure the stairs before you compare the retailers listed on this page. In the room, the slope usually decides the wall: put the headboard where you can sit up on a 33cm deep mattress.
