Key benefits
- Sized for shared rooms: At 135 x 190cm it fits most bedrooms, and we suggest at least 2.6m x 2.8m, with around 3m x 3m giving comfortable space to move.
- Room for bedside tables: In a typical master bedroom, a UK double usually leaves space for a bedside table on each side, so neither of you is reaching over the other for a lamp.
- A soft feel for two side sleepers: The medium soft wool and silk fillings give a cushioned surface, which means couples who both sleep on their side get shoulder give at 67.5cm each.
- Easy to dress: Double sheets and a 200 x 200cm duvet fit, although the 32cm depth means you'll want deep fitted sheets that tuck fully under.
- A welcoming guest bed: If visiting couples stay in your spare room, a UK double lets them share comfortably without the bed crowding out a wardrobe or drawers.
This size suits you if...
You share the bed with a partner and your bedroom is a typical UK size, rather than one with space to spare. It also fits if you're kitting out a guest room for visiting couples, or you sleep alone with a dog or cat who likes their own corner.
Consider another size if...
Your bedroom is smaller than our suggested 2.6m x 2.8m, so a UK double would leave little room to walk around it. We'd recommend the UK small double instead, which needs at least 2.4m x 2.8m.

FAQ's
Is the Millbrook Wool Sublime Pocket 5000 UK double big enough for two people?
For most couples, yes. A UK double gives 67.5cm each when two people share. If one of you sprawls or you're both broad-shouldered, the UK king gives 75cm each, which is 7.5cm more per person, but it needs a bigger room.
What size bedroom do I need for a UK double mattress?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That larger figure is what lets you fit a bedside table on both sides and still open a wardrobe without squeezing past the bed.
Should I get the UK double or UK king Millbrook Wool Sublime Pocket 5000?
The UK double is 15cm narrower and 10cm shorter than the UK king. If your room is tight, the UK double keeps space for furniture. If you have at least 2.7m x 2.9m and want more personal space, the UK king is the roomier choice.
Is a UK double long enough for tall sleepers?
The UK double is 190cm long. Taller sleepers whose feet reach the end may prefer the UK king, which is 10cm longer, provided the room allows our suggested 2.7m x 2.9m for that size.
What sheets fit the Millbrook Wool Sublime Pocket 5000 in a UK double?
Standard double sheets fit the 135 x 190cm surface, and a 200 x 200cm double duvet covers two people well. The mattress is 32cm deep, so check the pocket depth on fitted sheets, as shallow ones may slip off the corners.
