Key benefits
- More room each than a UK double: At 75cm each, you get 7.5cm more personal space than on a UK double, which means fewer elbows when one of you rolls over.
- Length for a taller partner: The 200cm length (6ft 6in) adds 10cm over a UK double, so a partner over six foot can stretch out without their feet reaching the edge.
- Less disturbance from early starts: The 1000 inner pocket springs each sit in their own sleeve, so one partner getting up before dawn should send less movement across the bed.
- A gentle feel for side-sleeping couples: The medium soft wool top cushions hips and shoulders, although a heavier partner or a back sleeper may find it slightly too soft.
- Space without super king demands: We suggest at least 2.7m x 2.9m for a UK king against 3m x 2.9m for the UK super king, which helps in a new build master bedroom.
This size suits you if...
You share the bed every night and keep bumping into each other on a UK double, or one of you is over six foot and needs the 200cm length. It also suits couples whose alarms go off hours apart and who want a little more distance between them.
Consider another size if...
Your bedroom is smaller than 2.7m x 2.9m. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
How much space does each person get on a Millbrook Wool Sublime Pocket 5000 UK king?
Two people sharing get 75cm each. That's 7.5cm more each than on a UK double, which is enough to notice when you both sleep on your side. If you want more, the UK super king gives 90cm each, so a UK king gives 15cm less per person.
Is the Millbrook Wool Sublime Pocket 5000 king size long enough for someone over 6ft?
It's 200cm long, or 6ft 6in, which is 10cm longer than the UK double. For a partner over six foot, that extra length is often the real reason to upgrade. The UK super king is the same length, so sizing up beyond a UK king only adds width.
What size bedroom do I need for a UK king Millbrook Wool Sublime Pocket 5000?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. A new build master bedroom can feel smaller than its floor plan once wardrobes go in, so measure around existing furniture. King sheets and a 230 x 220cm king duvet will fit.
Should I get a UK king or UK super king Millbrook Wool Sublime Pocket 5000?
The UK super king gives 90cm each against 75cm on a UK king, which helps if a dog sleeps on the bed or one of you sprawls. It needs more floor space, though: we suggest at least 3m x 2.9m for the UK super king versus 2.7m x 2.9m for the UK king.
Is a king size Millbrook Wool Sublime Pocket 5000 good if my partner gets up early?
It should help. The UK king is 15cm wider than a UK double, so there's more distance between you, and the individually sleeved pocket springs keep movement fairly local. The soft top does let you sink in slightly, so a very restless partner may still be felt a little.
