Key benefits

Key Benefits of the Millbrook Wool Sublime Medium Pocket 8000 Super King Mattress

  • 90cm each for two sharing: Each sleeper gets 90cm of width, which means a restless partner can turn over without dragging you awake, distance doing what no comfort layer can.
  • 30cm wider than the UK king: That works out at 15cm more space per person than the UK king, a difference you feel most on nights when the whole household ends up in one bed.
  • Pocket springs across a wide surface: Pocket springs respond to each sleeper independently, which matters more at this width, where two people of different weights can settle without tilting towards each other.
  • Full 200cm length: The same length as the UK king, so taller sleepers get the extra 10cm over standard 190cm sizes without paying a length penalty for the width.
  • Room needed is the real cost: We suggest a bedroom of at least 3m x 2.9m, so measure before you order rather than after it arrives.

Who should buy the Millbrook Wool Sublime Medium Pocket 8000 Super King Mattress?

This size suits you if...

You share the bed every night and one of you is a genuinely restless sleeper, or children and pets treat your bed as theirs and everyone still needs a fair share of the mattress. It also suits you if you have a large master bedroom, perhaps in a period property, where a UK king would look a little lost against the wall.

Consider another size if...

Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or you struggle to justify super king bedding costs. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m and still gives 75cm each.

FAQ's

Frequently Asked Questions About the UK Super King

Is the super king Millbrook Wool Sublime big enough for a family sharing?

It is the most forgiving standard size for it. Two adults get 90cm of width each, so when a child wanders in at 3am there is genuine space to absorb them rather than everyone shuffling to the edges. Across the 180cm width, the pocket sprung construction also limits how much one person's movement carries to the others.

What room size do I need for the Millbrook Wool Sublime in a UK super king?

We suggest a bedroom of at least 3m x 2.9m for a UK super king, and that is a genuine minimum rather than a comfortable one. Check door swing and any tight landing turns before ordering too, because a 180 x 200cm mattress is an awkward thing to manoeuvre through a narrow hallway.

Should I choose the super king or the UK king version of this mattress?

If your room takes it, the UK super king is the better buy for a couple. It is 30cm wider than the UK king at the same 200cm length, giving each of you 15cm more space. If your room is closer to the 2.7m x 2.9m we suggest for the UK king, size down rather than squeeze.

How much more space does the super king give a couple than a double?

A meaningful amount. The UK super king is 45cm wider and 10cm longer than the UK double, and where the UK double gives 67.5cm each for two sharing, the UK super king gives 22.5cm more per person. For couples upgrading from a double, that is usually the single biggest comfort improvement available.

Is the Millbrook Wool Sublime super king easy to find in stock?

Availability for this size can be thinner than for the smaller sizes, so it may take slightly more effort to find. The retailer table on this page is updated as stock and prices change, so compare what is listed here rather than relying on a single shop's listing.
