Layer Details
Pillow top
A top layer of foam added to increase cushioned comfort. It makes the surface feel gentler without changing the firm rating.
Memory foam
A 3cm layer of plush memory foam in the centre of the mattress. It gives some contouring and pressure relief above the firmer layers.
Hard foam base
A base of hard foam that offers strong support to the areas you need it most. It keeps the mattress feeling firm and stable.
Pocket springs core
1500 pocket springs, each individually encased in its own pocket. They respond separately, which gives the mattress its supportive, orthopaedic-style base.

Key benefits
- Room for two in an ordinary bedroom: At 135 x 190cm it gives each of you 67.5cm, and it sits comfortably in rooms where a UK king would crowd out the furniture.
- Less drifting towards the middle: SleepSoul lists no roll-together, which means two adults sharing a UK double are less likely to slide into a dip between them during the night.
- Firm support right across the surface: The 1500 individually pocketed springs respond separately, which means each of you is held up by the springs beneath you rather than by one shared, sagging area.
- Bedding you can buy anywhere: Standard double sheets and a 200 x 200cm double duvet fit, so you won't be searching for specialist sizes when you set up the room.
- Extra width if you sleep alone: If you sleep solo and a dog or cat tends to claim one corner, the UK double gives you 45cm more width than the UK single.
This size suits you if...
You share your bed with a partner every night and want firm support in a size that suits a typical UK bedroom, or you're setting up a guest room for visiting couples. It also fits if you sleep alone but like plenty of space for yourself and a pet.
Consider another size if...
Your bedroom is smaller than our suggested 2.6m x 2.8m, or bedside tables won't fit on both sides. We'd recommend the UK small double instead, which needs at least 2.4m x 2.8m.

FAQ's
Is the SleepSoul Luna 1500 Ortho Pillow Top double big enough for two people?
For most couples, yes. You each get 67.5cm of width, which is the traditional UK standard for sharing. That's 7.5cm less each than a UK king would give, but SleepSoul doesn't make this mattress in a UK king, so the UK double is the roomiest option for this model.
What size bedroom do I need for a UK double Luna 1500?
We suggest at least 2.6m x 2.8m. Around 3m x 3m is more comfortable, as it leaves room for a bedside table on each side and space to open wardrobe doors. In a smaller second bedroom, measure where the drawers and wardrobe will go before you commit.
Should I choose the UK double or the UK small double Luna 1500?
The UK double is 15cm wider than the UK small double, and the two are the same length. For a couple sharing nightly, those 15cm make a real difference. If your room is tight, the UK small double needs at least 2.4m x 2.8m, against our 2.6m x 2.8m suggestion for the UK double.
How big is a UK double SleepSoul Luna 1500 in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. That's the standard UK double footprint, so it fits a normal double bed frame or divan base without any special ordering.
Is a UK double Luna 1500 a good choice for a guest room?
It can be, if your visitors are usually couples. The UK double gives two guests 67.5cm each without filling a modest spare room. Bear in mind it's rated firm, so guests who prefer a soft, sinking feel may find it a little unyielding, even with the pillow top.
