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
- Leaves room for everything else: At 3ft x 6ft 3in, the UK single sits against one wall and still leaves floor space for a wardrobe, a desk and toy storage in a smaller bedroom.
- A cooler foam layer for one: Mlily says the ventilated Bamboo Air Memory Foam encourages airflow, which means a teenager who runs warm should feel less heat build-up than on solid foam.
- Usable right to the edge: The Airtech border with an F-Joint system gives edge-to-edge support, which matters on a narrow bed where you sit on the side to dress or read.
- Pairs easily in a guest room: Two UK singles side by side let friends or siblings sleep apart, and each mattress takes standard single sheets and a single duvet (135 x 200cm).
- Nothing to turn: It's single-sided, so in a child's room or a rarely used spare bed there's no flipping routine to forget.
This size suits you if...
You sleep alone and want foam contouring over springs in a compact room, or you're kitting out a child's or teenager's bedroom where the desk and storage need the floor space, or your spare room doubles as an office and only has space for a narrow bed.
Consider another size if...
You share the bed, or you sprawl and a 90cm width already feels tight. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m for the UK double.

FAQ's
Will the Mlily Haluna Natural Pocket 2500 UK single fit a bunk bed or cabin bed?
It fits the 90 x 190cm UK single base, but the mattress is 27cm deep, which is more than many raised frames are designed for. Bunk, cabin and mid-sleeper beds usually state a maximum mattress depth so the guard rail stays high enough. Check the frame maker's guidance before ordering, especially for a top bunk.
What size is a Mlily Haluna Natural Pocket 2500 single in feet?
The UK single measures 3ft x 6ft 3in, or 90 x 190cm. That matches the standard UK single size, so it should drop into most single bed frames, divans and bunk bases sold in the UK without any gap at the sides or foot.
How big does a bedroom need to be for a UK single Mlily Haluna mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open drawers. In a loft conversion, the narrow footprint means you can tuck it under the sloping ceiling and keep the full-height part of the room clear.
Is the UK single Mlily Haluna long enough for a tall teenager?
The UK single is 190cm long, the same as the UK double. If your teenager is already close to that height, the UK king and UK super king are the longer options in this mattress, as the UK single is 10cm shorter than the UK king. Most children and teens will be comfortable on the UK single for years.
Does the Mlily Haluna Natural Pocket 2500 come in a UK small double?
No. Mlily offers this mattress in four sizes, and the UK small double isn't one of them. If the UK single feels too narrow, the next size up is the UK double: the UK single is 45cm narrower than the UK double, and we suggest at least 2.6m x 2.8m for the UK double.
