Key benefits
- More room each: You each get 75cm of width, which is 7.5cm more per person than a UK double, enough to stop elbows meeting when one of you turns over.
- Less disturbance on mismatched schedules: If one of you is up hours before the other, the UK king's extra 15cm of width over a UK double puts a little more distance between you.
- Length for taller sleepers: At 200cm, or 6ft 6in, the UK king is 10cm longer than a UK double, so a partner over six foot is far less likely to rest their feet on the edge.
- Zoned support across both sides: The seven spring zones run the full width, which means each of you gets support shaped to shoulders and hips rather than a uniform feel.
- Room for the dog without losing your spot: If a dog joins you most nights, the UK king's extra width over a UK double means the dog takes some of the spare space instead of yours.
This size suits you if...
You share a bed every night and feel cramped in a UK double, especially if one of you rises much earlier than the other. You'll also benefit if one partner is over six foot and the length matters more than the width, and your bedroom is at least 2.7m x 2.9m.
Consider another size if...
Your bedroom measures less than 2.7m x 2.9m, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Millbrook Sovereign Natural Pillow Top UK king big enough for two people?
Yes, for most couples. The UK king gives you 75cm each, which is 7.5cm more per person than a UK double. That sounds slight, but it's the difference most sharers notice first. If you both sleep sprawled out, the UK super king gives 90cm each.
Is a UK king mattress long enough if you're over six foot?
The UK king is 200cm long, which is 6ft 6in, and 10cm longer than a UK double. For a partner approaching or over six foot, that extra length is often the real reason to size up, more than the width.
What size bedroom do I need for a UK king Millbrook Sovereign?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m being comfortable once you add bedside tables and wardrobes. New build master bedrooms can feel smaller than their floor plans suggest, so measure with furniture in place.
Should I choose the UK king or UK super king Sovereign Natural Pillow Top?
The UK super king gives 90cm each, so the UK king gives 15cm less per person. Both are the same length. Choose the UK super king if your room is at least 3m x 2.9m and you both like plenty of space; otherwise the UK king suits most couples.
What bedding fits a UK king Millbrook Sovereign Natural Pillow Top?
King sheets fit the 150 x 200cm surface, and a 230 x 220cm king duvet covers two sleepers. The mattress is 31cm deep, so check that your fitted sheet's pocket is deep enough to tuck under comfortably.
