Key benefits
- Room to get away from a fidget: At 90cm each, a partner who turns all night is a full arm's length further off, and the individually pocketed springs help keep their movement on their own side.
- Space when the family piles in: A child arriving at 3am or a large dog on the foot of the bed no longer means one adult clinging to the edge.
- Extra length as well as width: The UK super king is 200cm long, 10cm longer than a UK double, which means taller sleepers are less likely to find their feet over the end.
- Proportions for a large bedroom: In a period house with high ceilings or a generous master bedroom, a UK king can look a little lost, and the UK super king fills the space properly.
- Handles for a heavy job: The Cotterdale can only be rotated, not flipped, and the built-in handles make turning a mattress this large much more manageable for two people.
This size suits you if...
You share the bed with someone who tosses and turns, or children and pets join you most nights, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or you sleep alone. We'd recommend the UK king instead: allow at least 2.7m x 2.9m.

FAQ's
Is the Cotterdale 13250 super king big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each on the UK super king, so a small child arriving in the night can usually fit between you without anyone being pushed to the edge. If a child sleeps with you every night as they grow, everyone will still feel it a little by morning.
What size bedroom do I need for a Harrison Spinks Cotterdale super king?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable once you add bedside tables on both sides. In a loft conversion, check where the ceiling slopes, because a bed this wide often only works against one wall.
How much bigger is the Cotterdale super king than the king?
The UK super king is 30cm wider than the UK king, and they are the same length. In practice that gives each of two sleepers 15cm more width: 90cm each on the UK super king compared with 75cm each on the UK king.
What duvet and sheets fit a super king Cotterdale 13250?
A 260 x 220cm duvet suits a UK super king, along with super king sheets. The Cotterdale is 37cm deep, so check the pocket depth on any fitted sheet before you buy, as standard sheets may not stretch over the pillow top.
Will a 6ft Harrison Spinks Cotterdale fit up my stairs?
The UK super king measures 180 x 200cm (6ft x 6ft 6in) and is 37cm deep, so it is a large, bulky mattress to carry. Measure door openings, how the doors swing and any tight landing turns first, then compare the retailers listed on this page.
