Key benefits
- 90cm of width each: Each sleeper gets 90cm, which means a partner who turns over all night is noticeably further away, with 15cm more each than the UK king.
- Movement stays on their side: The 1000 inner pocket springs each sit in their own cloth sleeve, so one person's turn travels less across the bed, and the extra width adds distance on top.
- Space for a child or a dog: A youngster who wanders in at night, or a large dog that sleeps on the bed as routine, can take a share without squeezing either adult out.
- In proportion in a big room: In a period house or a generous master bedroom, the 6ft x 6ft 6in footprint fills the space properly, where a UK king can look slightly undersized.
- Flipping is a two-person job: Yes, it's double sided so you can turn it to spread wear, but at 180cm wide you'll want a second pair of hands to do it.
This size suits you if...
You share the bed every night and want 90cm each, a restless partner keeps waking you, or children and dogs regularly end up in with you, and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or a tight landing turn would make getting a 180cm-wide mattress upstairs awkward. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
What size room do I need for a Millbrook Wool Sublime Pocket 5000 super king?
We suggest at least 3m x 2.9m, although around 3.5m x 3.2m feels more comfortable once bedside tables are in. Before buying, check that the bedroom door can open fully past the bed. In a loft conversion, the sloping ceiling usually decides which wall the headboard goes against, so measure from there.
How much room does each person get on a UK super king Wool Sublime Pocket 5000?
Two people sharing get 90cm each. That's 15cm more each than the UK king and 22.5cm more each than the UK double, which is the difference you feel when a partner sprawls or a child arrives in the middle of the night.
Super king or king for the Millbrook Wool Sublime Pocket 5000?
The UK super king is 30cm wider than the UK king and the same length. Choose the UK super king if a restless partner, children or a dog regularly share the bed. If your room can't clear 3m x 2.9m, the UK king, which needs at least 2.7m x 2.9m, is the better fit.
Is a super king Wool Sublime Pocket 5000 hard to flip?
It's double sided, so flipping and rotating it spreads wear across both faces. At 180 x 200cm and 32cm deep, though, turning it alone is awkward, and most couples will find it far easier with one person at each side.
What bedding fits a Millbrook Wool Sublime Pocket 5000 super king?
You'll need UK super king sheets and a 260 x 220cm duvet. The mattress is 32cm deep, so choose fitted sheets with a deep pocket, because standard ones can pull off the corners. Super king bedding also costs a little more than UK king sets.
