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 to sprawl on your own: At 30cm wider than the UK single, there's space to lie diagonally or starfish, with the firm pocket springs keeping you level wherever you settle.
- Kinder to a small floor plan: It is 15cm narrower than the UK double, which can decide whether the bedroom door swings clear or catches the corner of the bed frame.
- Less drift towards the middle: SleepSoul lists no roll-together for this mattress, so on a narrower bed you and a visiting partner are less likely to slide into each other overnight.
- Straightforward bedding: Small double is a standard 4ft UK size, so fitted sheets are easy to buy and a regular double duvet covers the bed comfortably.
- Manageable to rotate: It's single-sided with handles, so you turn it head to foot rather than flip it, and a 120cm width is easier to shift in a cramped loft conversion.
This size suits you if...
You sleep alone and keep ending up at the edge of a UK single, or your bedroom is too compact for a full double frame and a partner only stays over now and then rather than every night.
Consider another size if...
You share the bed every night, because the UK small double gets tight for two week in, week out. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m.

FAQ's
Is the SleepSoul Luna 1500 small double big enough for two people?
For a weekend guest or a partner who stays occasionally, yes, and the lack of roll-together helps on a narrower surface. For nightly sharing it is a squeeze. The UK double is 15cm wider at the same length and gives 67.5cm each, so we'd point regular couples there.
What size bedroom do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk round the bed and open a wardrobe. If your room is smaller than that, the UK single needs at least 2.1m x 2.8m by our guidance.
Should I get the Luna 1500 Ortho Pillow Top in a small double or a double?
Both are 190cm long, so the choice is about width. The UK small double is 15cm narrower, which suits a solo sleeper in a compact room. If two of you share every night, the UK double is the better fit, provided your room allows at least 2.6m x 2.8m.
Is the Luna 1500 small double long enough for a tall sleeper?
The UK small double is 190cm (6ft 3in) long, the same as the UK single and UK double. A UK king is 10cm longer, but SleepSoul doesn't make this mattress in a UK king, so very tall sleepers who need extra length would have to look at a different model.
What sheets fit a UK small double mattress that is 31cm deep?
Buy small double (4ft) fitted sheets, and choose a deep-pocket style because this mattress is 31cm deep, which is more than some standard sheets are cut for. A regular double duvet works well on top and hangs a little over each side.
