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.

- Room for two without dominating the room: At 4ft 6in x 6ft 3in, this is the size that leaves space for bedside tables on both sides in a typical UK bedroom.
- 2500 springs shared between two sleepers: Each spring reacts on its own, which means your partner's midnight shuffle stays on their side of the 135cm width.
- Cooler sharing: Two bodies raise the temperature under any duvet, so the open cell Fusion Cool foam and knitted cover matter more in a shared double than in a single.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit, stocked everywhere at every price point.
- A sensible guest room choice: The medium firm feel suits a wide range of visiting sleepers, and the double footprint fits most spare rooms.
This size suits you if...
You share the bed every night and want proper couple space in a room where a bigger bed would crowd out the wardrobe, or you're furnishing a spare room that needs to sleep visiting couples comfortably. It also suits a solo sleeper who likes to spread out, medium firm support included, with enough spare width that a dog or cat claiming a corner doesn't push you to the edge.
Consider another size if...
You and your partner both like a lot of personal space, since 67.5cm each is workable rather than generous. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and we suggest a room of at least 2.7m x 2.9m for it.

Is the Luna Memory 2500 in a UK double big enough for a couple?
Yes, for most couples. The UK double is 135cm wide, giving 67.5cm each for two people sharing, and the 2500 pocket springs respond individually so you feel less of each other's movement. If either of you is broad shouldered or a restless sleeper, the UK king's extra 15cm of width is the more comfortable long term buy.
What room size do I need for the Luna Memory 2500 double?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. Measure with the wardrobe doors open, as that's usually where a double gets tight.
Should I get the Luna Memory 2500 in a UK double or size up to the UK king?
Go double if your room is close to the 2.6m x 2.8m minimum, or if a bigger bed would leave no space for other furniture. Size up if you share nightly and value space over floor room: the UK king is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m for it.
Will the Luna Memory 2500 double get up narrow stairs?
It's a 25cm deep hybrid with a pocket spring core, so it arrives as a full size mattress rather than rolled small. At 135 x 190cm the double is manageable on most staircases, but if you're in an older terrace with a turning stair or a tight new build landing, measure the awkward point first.
Is the double a good size for a guest room?
It's the safest choice. A UK double sleeps visiting couples without swallowing a smaller spare room, and the medium firm feel of this mattress suits back and stomach sleepers, which covers most guests. If the room only just fits a bed and wardrobe, the UK small double is 15cm narrower and the same length.
