Key Benefits of the Millbrook Wool Sublime Medium Pocket 11000 Super King Mattress

  • 90cm each for two sharing: With 90cm each for two people sharing, a restless partner mid-fidget is far enough away that you may simply not notice.
  • Room for the whole household: When children wander in during the night, or a large dog treats the bed as its own, this size means nobody ends up clinging to an edge.
  • 15cm more each than the UK king: The UK super king is 30cm wider than the UK king and the same length, giving each sleeper 15cm more than the UK king's 75cm.
  • A medium pocket sprung feel at full width: Pocket springs respond to each sleeper independently, which means one heavier or lighter partner shouldn't pull the other into a dip across all that width.
  • Suits larger master bedrooms: In a period property or a big new build master, a smaller size can look lost, while a UK super king fills the room in proportion.

Who should buy the Millbrook Wool Sublime Medium Pocket 11000 Super King Mattress?

This size suits you if...

You share every night and want the most sleeping space a standard UK size offers, your partner turns over often enough that distance matters more than any comfort layer, or children and pets regularly join you and you'd rather everyone kept a fair share. Your room should measure at least 3m x 2.9m by our guidance, with more feeling comfortable.

Consider another size if...

Your bedroom is under the 3m x 2.9m we suggest, or the bed would dominate the room. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

How much space do two people get on a super king Millbrook Wool Sublime?

Two people sharing get 90cm each, the same width per person as a UK single. Across a medium pocket sprung mattress like this one, that means a partner who shifts around at night is doing so at a genuine distance from you, and the springs respond to each of you separately rather than as a pair.

Is the Millbrook Wool Sublime better in a UK king or a UK super king?

The mattress itself is the same; the difference is space. The UK super king is 30cm wider than the UK king and the same length, so each sleeper gains 15cm over the UK king's 75cm. If your room comfortably clears 3m x 2.9m and disturbance is your main complaint, the extra width is what fixes it.

What room size do I need for this mattress in a UK super king?

We suggest a room of at least 3m x 2.9m, and that's our guidance rather than Millbrook's. That allows walking space on both sides and room for bedside tables. Before ordering, check door swing and any tight landing turns, because a 180 x 200cm mattress is an awkward thing to move upstairs.

Where can I buy the Millbrook Wool Sublime 11000 in a super king?

Availability for this size is limited, so compare the retailers listed on this page; the prices shown here are updated as retailers change them. It's also sensible to confirm the full specification, delivery arrangements and access requirements directly with the retailer before you commit, since a super king is a considerable delivery.

Is a super king mattress worth it for a family bed?

If children wander in at night or a large dog sleeps with you as routine, yes, this is the size where that stops costing the adults their sleep. At 180cm wide, the same footprint as two UK singles side by side, three bodies fit without anyone being pushed to the edge.
