Key benefits

Key Benefits of the Millbrook Wool Sublime Pocket 4000 Double Mattress

  • Room to share: At 67.5cm per person, the UK double gives each partner a defined strip of the mattress, which means less nudging for couples who settle close.
  • Fits an average bedroom: We suggest at least 2.6m x 2.8m, so in a typical main bedroom a UK double can usually sit with a bedside table on each side.
  • Bedding is easy to find: Standard double sheets fit, and a 200 x 200cm double duvet covers two sleepers, which helps if you're kitting out a whole home on a stretched budget.
  • Steady support for two: The medium-firm feel gives both of you consistent support, although a lighter side sleeper sharing with a heavier partner may find it a little firm.
  • Suits a guest room: A UK double hosts a visiting couple comfortably, and being double-sided means you can flip it between visits so wear stays even on both surfaces.

Who should buy the Millbrook Wool Sublime Pocket 4000 Double Mattress?

This size suits you if...

You share the bed with a partner and your bedroom is around average size, or you sleep alone but like space for a dog or cat curled up at your feet. It also suits a guest room where visiting couples stay.

Consider another size if...

One of you sprawls or sleeps restlessly, and 67.5cm each would feel tight. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Double

Is a UK double Millbrook Wool Sublime Pocket 4000 big enough for two people?

For most couples, yes. The UK double gives 67.5cm each, which works if you sleep fairly close or one of you is slim. If either of you sprawls, or you're both broad-shouldered, the UK king gives 75cm each and may feel noticeably roomier.

What size bedroom do I need for a UK double mattress?

We suggest at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable. That leaves walking space round the bed and usually room for a bedside table each side. In a smaller second bedroom with a wardrobe and drawers, check the door swing before you commit.

Millbrook Wool Sublime Pocket 4000 double or king: which should couples choose?

The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is closer to 2.6m x 2.8m, since we suggest at least 2.7m x 2.9m for the UK king. Taller couples may prefer the extra length of the UK king.

What bedding fits a UK double Millbrook mattress?

Standard double fitted sheets made for a 135 x 190cm bed, plus a 200 x 200cm double duvet. Because this mattress is 31cm deep, choose deep-pocket fitted sheets so the corners stay put when you or your partner turn over.

How big is a UK double Millbrook Wool Sublime Pocket 4000 in feet?

The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. That's the traditional British double, so bed frames and bedding labelled as a standard double should match it.
