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
- 90cm each when sharing: Each of you gets 90cm of width, which means a restless partner's turning is far less likely to wake you than on a narrower bed.
- Room for a small visitor: When a child climbs in after a bad dream, a UK super king leaves both adults a usable share rather than a sliver at the edge.
- Usable edges across the full width: Mlily's Airtech border with its F-Joint system is designed to support the sides, so the outer edges of a wide bed should feel sleepable rather than sagging.
- 15cm more each than the UK king: The UK super king gives 15cm more each than the UK king at the same length, so the gain is purely sideways room.
- In proportion in a large room: In a big master bedroom or a high-ceilinged period room, a UK super king fills the space properly where a UK king can look a little lost.
This size suits you if...
You share the bed with a partner who moves a lot, and you want as much distance as a standard UK size allows. It also suits you if children or a large dog regularly join you overnight, and your bedroom comfortably clears 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or two of you sleep still and close. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

FAQ's
How much space does each person get on a Mlily Haluna Natural Pocket 2500 UK super king?
Two people sharing get 90cm each on the UK super king. That is 22.5cm more each than the UK double and 15cm more each than the UK king. If one of you is a restless sleeper, that extra distance tends to make the biggest difference.
What size bedroom do I need for a UK super king Mlily Haluna?
We suggest allowing at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling right once you add bedside tables on both sides. In a loft conversion, measure where the ceiling slopes, because the slope usually decides which wall the bed can go against.
Is a UK super king big enough for two adults and a child?
For occasional visits, yes. At 180cm wide, a young child can fit between two adults without anyone ending up on the edge. If you co-sleep as a family every night, measure carefully first, because this is as wide as standard UK sizes go.
How much wider is the Mlily Haluna super king than the king?
The UK super king is 30cm wider than the UK king, and both are the same length. If you are deciding between the two, width is the only thing you gain, along with a larger room requirement: we suggest at least 2.7m x 2.9m for the UK king.
What bedding fits a UK super king Mlily Haluna mattress?
You'll need UK super king sheets and a 260 x 220cm duvet. Bedding at this size usually costs more than for a UK king, so factor that into your budget. The mattress is 27cm deep, so check that your fitted sheets have deep enough pockets.
