Key benefits
- More room each than a UK double: The UK king gives 75cm each for two sharing, which means 7.5cm more per person than a UK double and a little more space before elbows meet.
- Length for a taller partner: The UK king measures 5ft x 6ft 6in and is 10cm longer than a UK double, so a partner over six foot is less likely to find their feet at the end.
- Less disturbance on early starts: The 13250 pocket springs each sit in their own cloth pocket and move independently, so one partner getting up should send less movement across a 150cm wide bed.
- Cushioning without the super king footprint: You get the Medium Soft pillow top across a full UK king, while needing less floor space than the UK super king, for which we suggest at least 3m x 2.9m.
- Handles for rotating a larger mattress: Built-in handles make rotating a 37cm deep UK king more manageable, which matters because this mattress can be rotated but not flipped.
- Standard king bedding fits: King sheets and a 230 x 220cm king duvet suit this size, so a shared duvet is less likely to be pulled off one side overnight.
This size suits you if...
You share the bed every night and the UK double has started to feel cramped, one of you is over six foot and keeps running out of length, or your schedules differ and you want a little more distance from a partner who gets up early.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the Cotterdale 13250 UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each for two sharing, compared with 67.5cm each on a UK double, so you each gain 7.5cm. If one of you sprawls or a dog regularly joins you, the UK super king gives 90cm each, though it needs a larger room.
How much longer is a UK king than a UK double?
The UK king is 200cm long, which is 10cm longer than a UK double. In imperial, the UK king measures 5ft x 6ft 6in. That extra length makes the biggest difference when one partner is over six foot and finds their feet reaching the end of a UK double.
What size bedroom do I need for a UK king mattress?
We suggest allowing at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m giving comfortable room to walk around both sides. New build master bedrooms can feel smaller than expected once wardrobes go in, so measure the space you'll actually have left.
Should I choose the Cotterdale 13250 in UK king or UK super king?
The UK king is 30cm narrower than the UK super king and the same length, giving 15cm less each for two sharing. Choose the UK king if your room is under our suggested 3m x 2.9m for the UK super king, or if 75cm each already feels roomy enough.
Will I feel my partner move on a UK king pocket spring mattress?
Probably less than on a UK double. The 13250 springs move individually, and the UK king's extra 7.5cm per person adds a little more distance between you. Across a Medium Soft pillow top you may still notice a partner turning, but early risers should cause less disruption.
