Key benefits
- Room to move apart: With 90cm each, a restless partner can turn over without reaching your side, which means the springs have less movement to carry across in the first place.
- Space for a small visitor: When a child wanders in at 3am, the UK super king still leaves both adults a usable strip rather than a sliver at the very edge.
- Fits a large dog as routine: If a big dog sleeps on the bed every night, the 6ft width means it can stretch out without pushing either of you towards the floor.
- Medium suits a mixed household: The medium rating sits in the middle ground, which is useful in a super king shared by two adults with different positions and preferences.
- Proportioned for a big room: In a period property or a large master bedroom, a 180cm wide bed looks in scale where a smaller size can leave the room feeling oddly empty.
This size suits you if...
You share with a genuinely restless partner and want real distance between you, your children or a large dog join you most nights, or your bedroom comfortably clears our suggested minimum of 3m x 2.9m and a smaller size would look lost in it.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or you would lose space for bedside tables. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How much bigger is the Polperro Miracoil Memory super king than the king?
The UK super king is 30cm wider than the UK king, and the two are the same length. For a couple, that works out at 15cm more each: 90cm per person against 75cm on the UK king. If you're mainly sizing up to escape a restless partner, that extra width is what you're paying for.
Is a UK super king Polperro big enough for two adults and a child?
For occasional visits, usually yes. Two adults get 90cm each, so a small child climbing in after a bad dream can fit between you without anyone ending up on the edge. If a child shares with you every night for months, expect it to feel snug, although far less cramped than on a UK king.
What size bedroom do I need for a super king Silentnight Polperro?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable. In a loft conversion, measure where the ceiling slopes down, because the full-height wall usually decides where a bed this wide can go and how easily you can get in on both sides.
Will a super king mattress fit up my stairs and through the bedroom door?
At 180cm wide and 28cm deep, this is a large mattress to carry. Before ordering, measure tight landing turns, low stairwell ceilings and how far your bedroom door opens. Then compare the retailers listed on this page once you're confident it will make the trip upstairs.
What bedding fits a UK super king Polperro Miracoil Memory?
You'll need super king fitted sheets deep enough for a 28cm mattress, and a 260 x 220cm duvet gives proper overhang on both sides. Super king bedding costs more than king, so factor in a couple of sets of sheets when you budget for this size.
