Layer Details
- Knitted cover. A soft knitted cover that adds a touch of cosiness and warmth. Knitted covers also enhance airflow, so the surface stays breathable.
- Luna Fusion Cool Memory Foam. A 4cm layer of memory foam with an open cell structure, which means it breathes better and feels cooler than standard memory foam. You get the contouring without as much of the heat.
- Reflex Foam. Reflex foam in 2cm and 3cm layers adds cushioning and reinforces the medium to firm feel. It moulds to your body while promoting spinal alignment.
- Luna Pocket Springs. A core of 2500 Luna pocket springs, each encased in its own cloth pocket. They respond individually to movement, which means personalised support and less disturbance when a partner shifts.

- Fits where space is tight: At 90cm wide it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or slots under the slope of a loft conversion.
- Medium firm suits growing bodies: The structured, medium firm feel keeps a child or teenager's spine aligned rather than letting them sink, which many parents specifically look for.
- Guest rooms that earn double duty: A UK single works well in a spare room that is also an office, and two singles can host visiting family where one double would not.
- Cooler than standard memory foam: The 4cm Fusion Cool layer has an open cell structure, which means a teenager who sleeps warm gets contouring without the trapped heat.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and lowest priced of any UK size, a small saving that adds up over years.
This size suits you if...
You're buying for a child or teenager and want proper support rather than a budget foam slab, you need a guest bed for a spare room that spends most of its life as a study, or you're kitting out a student room or first flat where the frame is provided and the mattress isn't. The 90 x 190cm footprint suits almost any UK bedroom.
Consider another size if...
You're an adult who shares the bed, or a restless solo sleeper who wants more than 90cm of width. We'd recommend the UK small double, which is 30cm wider and the same length; allow at least 2.4m x 2.8m for it.

Will the Luna Memory 2500 single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, but check depth before you buy. This mattress is 25cm deep, and many raised frames specify a maximum mattress depth so the guard rail stays high enough. Measure from the base to the rail top and compare against your frame's guidance.
Is the Luna Memory 2500 in a UK single suitable for a child?
Yes, with one caveat. The medium firm feel and pocket spring support suit growing children and teenagers well, and the open cell foam runs cooler than standard memory foam. Very light children may find it a little solid at first, and owner feedback on this model suggests a short adjustment period is normal.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you a walkway and space to make the bed. That makes it a realistic fit for box rooms, lofts with a narrow usable footprint, and children's rooms where the bed shares space with a desk and wardrobe.
Can I fit two Luna Memory 2500 singles in one guest room?
Often, yes. Each mattress is 90cm wide, so two beds plus a walkway between them needs a reasonably generous room; sketch your layout against the 90 x 190cm footprint before ordering. Two singles give guests flexibility that one double doesn't, since friends or siblings each get their own bed.
Where can I buy the Luna Memory 2500 in a single?
Stock and pricing change regularly, so the most reliable answer is the live comparison table on this page, which updates as retailers change their prices. If the UK single shows limited availability, it's worth checking back, as listings for individual sizes come and go more often than for the model as a whole.
