Key benefits
- Room for a restless partner: With 90cm of width each, a partner who fidgets or gets up early is far less likely to wake you, and distance helps more here than any surface layer.
- Space when the family piles in: A child who wanders in after a bad dream, or a large dog who sleeps on the bed as a matter of course, can fit without anyone clinging to the edge.
- Fills a large room properly: In a generous master bedroom or a tall-ceilinged period room, a UK super king sits in proportion, where a UK king can look slightly lost against the wall.
- Season swap across the whole bed: Both of you move to the summer or winter side at once, although turning a mattress this wide and 39cm deep is a two-person job.
- Pillow top you can take off: The cashmere pillow top covers the full 180cm width and comes off if the softer surface doesn't suit either of you.
This size suits you if...
You share the bed every night with someone who moves a lot, your children or a large dog regularly end up in with you, or your main bedroom is big enough that a smaller bed would look undersized against the wall.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or the landing and doorways are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is a UK super king Flaxby Silkstone big enough for two adults and a child?
For occasional visits, yes. At 180 x 200cm you each get 90cm when two of you share, so a small child tucked between you still leaves both adults some room. If a child sleeps with you every night, the UK super king is the size that keeps that arrangement comfortable rather than cramped.
What size bedroom do I need for a Flaxby Silkstone UK super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right once you add bedside tables on both sides. In a loft conversion, measure where the ceiling slopes, because that usually decides which wall a bed this wide can go against. Check door swing and landing turns before ordering too.
Flaxby Silkstone UK king or UK super king for a restless sleeper?
The UK super king is 30cm wider than the UK king and the same length, giving each sleeper 15cm more. If a partner's tossing and turning is the main reason you're upgrading, that extra distance is what makes the difference. The UK king needs at least 2.7m x 2.9m, against 3m x 2.9m for the UK super king.
What bedding fits a UK super king Flaxby Silkstone?
You'll need super king sheets and a 260 x 220cm duvet. Look for deep fitted sheets, because this mattress is 39cm deep and standard pockets often won't reach round it. Bedding at this size costs more than for a UK king, so factor that in when you budget for the whole bed.
Can one person flip a Flaxby Silkstone super king between seasons?
We wouldn't plan on it. The summer and winter sides are the main reason to choose this mattress, but at 180 x 200cm and 39cm deep, turning a UK super king is awkward for one person. Plan to flip it with a second pair of hands, and leave space around the bed to do so.
