Key benefits
- Suits an everyday bedroom: We suggest a room of at least 2.6m x 2.8m, so most main bedrooms and plenty of second bedrooms can take it with space left to walk round.
- Space for a table each side: At 135cm wide, a UK double usually leaves room for a small bedside table on both sides, so neither of you clambers over the other at night.
- Spring support under both of you: Micro springs sit beneath the Serene foam, which means each sleeper gets support from springs rather than foam alone across their 67.5cm.
- A little easier to get upstairs: The UK double is 15cm narrower and 10cm shorter than the UK king, a small but real help on the turning stairs of an older terrace.
- Bedding you can buy anywhere: Standard double sheets fit, and a 200 x 200cm double duvet gives you both enough cover to stop any overnight tug of war.
This size suits you if...
You share the bed every night in a typical bedroom and still want bedside tables on both sides, or you're kitting out a first flat where the bed has to sit alongside a wardrobe and drawers, and a medium-firm hybrid feel appeals to you both.
Consider another size if...
One of you sprawls, or you'd both like more distance between you at night. We'd recommend the UK king instead, which gives 7.5cm more each and needs at least 2.7m x 2.9m.

FAQ's
Is the Blueberry Hybrid UK double big enough for two people?
For most couples, yes. A UK double gives 67.5cm each, which feels comfortable if you both sleep fairly still. If one of you sprawls, the UK king gives 75cm each and is 10cm longer, which taller sleepers will appreciate too.
What size bedroom do I need for a UK double Blueberry Hybrid?
We suggest at least 2.6m x 2.8m. That leaves enough floor to get round the bed, although around 3m x 3m feels more comfortable once you add bedside tables, a wardrobe and drawers. In a smaller second bedroom, measure where the wardrobe doors open before you commit.
How big is a UK double mattress in feet?
A UK double is 4ft 6in x 6ft 3in, or 135 x 190cm. It is the same length as the UK small double and the UK single, so the extra space goes entirely into width rather than legroom.
Should I get the Blueberry Hybrid in a UK double or a UK small double?
The UK double is 15cm wider and the same length. For two adults sharing, those extra centimetres make a noticeable difference. A solo sleeper in a compact room may be happy with the UK small double, for which we suggest at least 2.4m x 2.8m.
Will a UK double hybrid mattress fit up narrow stairs?
Measure first. This mattress is 135cm wide and 24cm deep, with micro springs inside, so check the tightest turn on the stairs and the landing width in a new build or older terrace. Once you know it will go up, compare the retailers listed on this page.
