Key benefits
- Distance from a restless partner: Each sleeper gets 90cm, so a partner who shifts all night is far enough away that you are less likely to feel every turn through the springs.
- Room for night-time visitors: If small children wander in or a large dog sleeps on the bed every night, the 6ft width means the adults still keep a usable share of the mattress.
- Extra length over smaller sizes: At 200cm long, the UK super king suits taller sleepers who find their feet hanging over a 190cm UK double or UK small double.
- Scale for a large master bedroom: In a high-ceilinged period room or a spacious master, a UK king can look a little lost, whereas the UK super king fills the wall more convincingly.
- Firm support across the full width: The medium-firm pocket spring feel stays consistent from edge to edge, which helps when you spread out and sleep away from the centre.
This size suits you if...
You share the bed every night with a partner who moves a lot, your children or dogs regularly end up in it too, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is tight for space or has awkward sloping walls. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m by our guidance.

FAQ's
What size is the Millbrook Wool Sublime Pocket 4000 UK super king?
It measures 180 x 200cm, which is 6ft x 6ft 6in, and it is 31cm deep. With two people sharing, that works out at 90cm of width each.
How big does my bedroom need to be for a UK super king mattress?
We suggest allowing at least 3m x 2.9m, although around 3.5m x 3.2m feels more comfortable once you add bedside tables. Check the door swing too, as a 180cm-wide bed can easily block it. In a loft conversion, the slope of the ceiling usually decides which wall the bed can go against.
Is a UK super king worth it over a UK king for a restless partner?
For a genuinely restless sleeper, extra distance tends to help more than any comfort layer. The UK super king is 30cm wider than the UK king and gives you 15cm more each, with both sizes the same length. If your room can take it, that extra width is what you're paying for.
Can you flip a super king Millbrook Wool Sublime Pocket 4000 on your own?
It is double-sided, but flipping a mattress 180cm wide and 31cm deep is realistically a two-person job. Millbrook doesn't publish a weight for this mattress, so plan on help each time you turn or rotate it.
What bedding fits a UK super king Millbrook mattress?
You'll need super king sheets and a 260 x 220cm duvet. Because the mattress is 31cm deep, choose a deep fitted sheet so the corners stay put. Super king bedding costs a little more than smaller sizes, so factor that in.
