Key benefits
- Fits an ordinary bedroom: We suggest a room of at least 2.6m x 2.8m, which means most couples can keep bedside tables on both sides and still open the wardrobe.
- Zoned support on each half: The seven spring zones run across the full 135cm width, so each of you gets support shaped to your own body on your own side.
- A shared medium feel: The pillow top cushions the whole surface, which gives two people with slightly different tastes a middle ground that suits most back and side sleepers.
- Easy bedding: Double sheets and a 200 x 200cm double duvet fit, so replacement linen is easy to find in any shop at any budget.
- Air for two warm bodies: Integrated side air vents help air move through the mattress, a modest help when two people are warming the same bed all night.
This size suits you if...
You share the bed with a partner in a standard UK bedroom and want space left for bedside tables and a wardrobe, or you sleep alone with a dog or cat that claims a corner and you like a cushioned medium feel.
Consider another size if...
You and your partner sprawl, or one of you is tall, and 67.5cm each already feels tight. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's
Is a UK double Millbrook Sovereign big enough for two people?
For most couples, yes. The UK double gives 67.5cm each, which is comfortable if you both sleep fairly still. The UK king gives 75cm each, so the UK double gives 7.5cm less per person. If either of you spreads out or a pet joins you, that difference becomes noticeable.
What size room do I need for a UK double mattress?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That usually allows a walkway on each side and a pair of bedside tables. In a smaller second bedroom, measure for wardrobe doors and drawers too, since they need clearance the bed can't share.
Millbrook Sovereign double vs king: what's the difference?
The UK double is 15cm narrower and 10cm shorter than the UK king. The pillow top, medium feel and spring zoning are the same in both, so the choice comes down to space. We suggest at least 2.7m x 2.9m for the UK king, compared with 2.6m x 2.8m for the UK double.
What are the Millbrook Sovereign double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. It is 31cm deep, so check that your fitted sheets are made for a mattress of that depth before you buy them.
Is a UK double Sovereign a good choice for a guest room?
It suits a guest room that hosts visiting couples, since 67.5cm each is a sensible share for a few nights. The medium feel with a pillow top tends to suit most back and side sleepers, so it's a safe pick for guests whose preferences you don't know. Double bedding is simple to buy and change between visits.
