Key benefits

Key Benefits of the Millbrook Wool Sublime Medium Pocket 8000 Double Mattress

  • A footprint most bedrooms can take: At 135 x 190cm, or 4ft 6in x 6ft 3in, it fits comfortably in rooms where a UK king would leave little walking space.
  • Room for bedside tables on both sides: In an average double bedroom you can usually keep a table each side, which a wider mattress often rules out.
  • 67.5cm each for two sharing: That's the traditional couples' allowance, fine for most, although restless pairs may want more.
  • Easy to dress: Standard double sheets and a 200 x 200cm duvet are stocked everywhere at every price, useful if you're kitting out a whole home at once.
  • Simpler to get upstairs: A UK double is easier to turn on the stairs of an older terrace or a tight new build landing than a UK king or UK super king.

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

This size suits you if...

You share the bed every night and your room sits around the typical UK double bedroom size, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also makes sense if you're furnishing a guest room for visiting couples. Allow at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm.

Consider another size if...

You're a couple with a larger room and either of you sleeps restlessly, because 67.5cm each can feel snug. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

FAQ's

Frequently Asked Questions About the UK Double

Is a UK double big enough for a couple on the Millbrook Wool Sublime?

Yes, for most couples. Two people sharing get 67.5cm of width each, the long standing UK standard for shared beds. If one of you moves around a lot at night, or you're both broad shouldered, the UK king gives 75cm each, which is 7.5cm more per person, so weigh that against your room size before deciding.

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

We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, a bedside table each. This is our own guidance rather than Millbrook's, so measure your room, including alcoves and door swing, before you commit.

Should I get the Millbrook Wool Sublime in a double or a king?

The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits smaller rooms and taller sleepers under about 6ft. Couples with the space usually appreciate the UK king's extra 7.5cm each. If your bedroom is under 2.7m x 2.9m, our suggested minimum for the UK king, the UK double is the safer choice.

Will a UK double mattress fit up a narrow staircase?

Usually, yes. At 135cm wide a UK double is one of the easier sizes to manoeuvre, and pocket sprung mattresses like this one can flex a little on a turn. If you live in an older terrace with a tight half landing, measure the pinch point first, and remember the UK king would be 15cm wider still.

What bedding fits the Millbrook Wool Sublime double?

Standard UK double sheets, made for 135 x 190cm mattresses, and a 200 x 200cm double duvet. Both are sold everywhere at every price point, which makes this size cheap and easy to dress, a genuine plus if you're furnishing a first flat or several rooms at once.
