Layer Details
Wool and bamboo memory foam cover
A quilted cover that blends wool with bamboo memory foam, with a stretch knit finish. It gives a plush top surface and a naturally soothing feel.
Bamboo Air Memory Foam
A ventilated memory foam layer that encourages airflow through the mattress. Mlily says this helps regulate body temperature, so you stay cooler for longer.
Flex Comfort Foam
A responsive foam layer that adapts to your body contours. It adds cushioning between the memory foam and the springs.
Pocket springs
Mlily's 2500 H-Spring system of individually wrapped springs. It adds to the feeling of comfort while giving all-over support as you sleep.
Flex Support Foam
A custom foam base layer that provides support from the bottom up. It gives the springs a stable foundation.

Key benefits
- Fits typical UK bedrooms: At 4ft 6in x 6ft 3in, it sits comfortably in rooms where a UK king would leave you edging sideways around the frame.
- Room for bedside tables: We suggest at least 2.6m x 2.8m, with around 3m x 3m giving you space for a bedside table on each side.
- Usable edges when sharing: The Airtech border with its F-Joint system supports the sides, which means each of you can use your full 67.5cm without rolling towards the middle.
- Cooler for two bodies: Two people generate more heat than one, so the ventilated Bamboo Air Memory Foam layer is a helpful feature on a shared UK double.
- Easy bedding to find: Standard double sheets and a 200 x 200cm double duvet fit, so you won't need to replace bedding you already own.
This size suits you if...
You share a bed with your partner in a typical UK bedroom and want proper sleeping space without the bed taking over, or you're setting up a guest room for visiting couples, or you sleep alone but your dog or cat insists on its own corner.
Consider another size if...
You're both tall or already feel crowded at 67.5cm each. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the Mlily Haluna Natural Pocket 2500 UK double big enough for two people?
For most couples, yes. A UK double gives you 67.5cm each, and the supported Airtech border means the outer edges feel usable rather than sagging. If either of you sprawls or you wake each other often, the UK king gives 7.5cm more each, which you'll notice over a full night.
What size bedroom do I need for a UK double Mlily Haluna?
We suggest at least 2.6m x 2.8m. Around 3m x 3m is more comfortable, as it lets you fit a bedside table on both sides and still open a wardrobe door. In a smaller second bedroom, measure where drawers and doors swing before you commit.
Mlily Haluna UK double or UK king: which should a couple choose?
Choose by your room as much as your comfort. The UK double is 15cm narrower and 10cm shorter than the UK king. We suggest at least 2.7m x 2.9m for the UK king, so if your room falls short of that, the UK double is the better fit.
What bedding fits a UK double Mlily Haluna mattress?
Double fitted sheets and a 200 x 200cm double duvet fit the 135 x 190cm surface. The mattress is 27cm deep, so check the pocket depth on any fitted sheet you buy, as shallow ones can slip off the corners.
Is a double worth it over a single for one person with a pet?
Often, yes. The UK double is 45cm wider than the UK single, which gives a cat or dog its own patch without pushing you to the edge. We suggest at least 2.1m x 2.8m for the UK single, so check your room against both.
