Layer Details
- Bamboo Charcoal Memory Foam. A 2cm top layer with air channels that let air flow through the mattress. The bamboo charcoal also absorbs moisture, which helps regulate temperature through the night.
- Flex Comfort Memory Foam. A 2cm layer of memory foam that cradles to your shape. This is where the cushioned, contouring feel comes from.
- Ortho Comfort Foam. A 3cm layer specifically engineered to ease back and joint pain. It sits between the softer comfort foams and the springs.
- Pocket Springs. 800 Ortho Firm pocket springs, each encased in its own cloth pocket so it moves independently. This means the mattress adapts to your movement and distributes support where your body needs it.
- Core Support Foam. A 4cm base layer of supportive foam that adds extra firmness. It promotes spinal alignment, underpinning the firm feel of the whole mattress.

- Leaves floor space for everything else: At 3ft x 6ft 3in, the UK single leaves room beside the bed for a desk and a chest of drawers, which matters in a box room or a busy child's bedroom.
- Firm support for back and front sleepers: The 800 pocket springs respond individually, which means a teenager who sleeps on their back or front gets a level spine rather than a dip in the middle.
- Slim enough for many raised frames: At 23cm deep it is slimmer than many hybrids, which helps on cabin beds and mid sleepers, although you should confirm the frame's maximum mattress depth before ordering.
- Two single beds for guests: A pair of UK singles lets two friends stay without sharing, and when guests leave, the room goes back to being a study.
- A little airflow in a small room: The bamboo charcoal top layer has air channels, which helps slightly in a compact bedroom, although hot sleepers may still feel some warmth from the memory foam.
This size suits you if...
you're buying for a child or teenager who sleeps on their back or front and needs a firm, supportive surface, or you're fitting a compact bedroom, loft conversion or raised frame where only a narrow bed will work.
Consider another size if...
you're a solo adult who likes to spread out, or a partner sometimes joins you. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

Will the Mlily Ortho Memory 800 single fit a mid sleeper or bunk bed?
The UK single measures 90 x 190cm, the standard footprint for most bunks and mid sleepers, and the mattress is 23cm deep. Raised frames usually set a maximum mattress depth so the safety rail stays high enough above the sleeper, so check the frame maker's guidance before you buy.
What size bedroom do I need for a Mlily Ortho Memory 800 single?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk around the bed and open a wardrobe, which is why the UK single works in box rooms and smaller children's bedrooms.
Is a single Mlily Ortho Memory 800 big enough for an adult?
For one adult of average build, the UK single's 90cm width is workable, although it leaves little room to turn over freely. If you're tall, the UK king is 10cm longer than the UK single, while the UK double adds width but keeps the same length.
Should I put two singles or one double Mlily Ortho Memory 800 in a guest room?
Two UK singles suit friends or siblings who would rather not share a bed. A UK double gives 67.5cm each for two sharing and needs at least 2.6m x 2.8m by our guidance, compared with 2.1m x 2.8m for one UK single.
Can the Mlily Ortho Memory 800 single go in a loft conversion?
Usually, yes. At 3ft wide, the UK single can sit lengthways along the lower wall under a sloping ceiling, leaving the higher part of the room free to stand in. Measure the head height where the pillow end will sit, as the mattress adds 23cm to the frame height.
