Layer Details
Pillow Top
An extra layer of plush fillings sewn onto the surface, which means a softer, more cushioned first impression when you lie down. It gives the medium firm core a gentler feel on pressure points like hips and shoulders.
Cool Gel Memory Foam
This foam contours to your body for pressure relief and support, while the gel helps regulate body temperature better than standard memory foam. In practice, you get the hug of memory foam with less of the heat build-up.
Pocket Springs
Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your body shape rather than pushing back as one unit. That independence also helps reduce disturbance when a partner moves.

Key benefits
- Leaves room for the rest of the bedroom: At 90 x 190cm, the UK single leaves space for a desk and a wardrobe in a child's bedroom, so homework and storage are not squeezed out by the bed.
- A slightly cooler feel for warm teens: The cool gel memory foam handles heat a little better than standard memory foam, which helps teenagers who tend to overheat under a single duvet.
- Two beds for siblings sharing: Two UK singles side by side give each child a bed of their own, and in a reasonably sized room you can keep a walkway between them.
- A proper bed in a study: In a study that doubles as a guest room, the UK single keeps the desk usable day to day while still giving visitors a pillow-top hybrid for the night.
- Fits under a sloping ceiling: The narrow footprint lets you tuck the UK single beneath the slope of a loft conversion, where a wider mattress would reach into the lowest headroom.
This size suits you if...
You sleep alone and want a pillow-top hybrid in a small room, or you are furnishing a child's or teenager's bedroom that also needs a desk and wardrobe, or you want a comfortable guest bed for a study or loft conversion.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Will the SleepSoul Wish 3000 UK single fit a mid sleeper or cabin bed?
The UK single is 90 x 190cm, the standard footprint that most raised frames are built around. Depth is the more likely problem. At 30cm, the Wish 3000 is deeper than many bunk, cabin and mid sleeper frames allow for, so check the frame maker's maximum mattress depth and the guard rail height before you buy.
Is the SleepSoul Wish 3000 in a UK single good for a child or teenager?
It suits most growing teenagers well, especially warm sleepers, because the gel memory foam feels a little cooler than standard memory foam. The medium firm feel is the thing to watch: lighter children who sleep on their side may find it a touch firm, although the pillow top softens the surface.
How much floor space do I need for a SleepSoul Wish 3000 single?
We suggest at least 2.1m x 2.8m for a UK single. That allows you to walk around the bed and open drawers or a wardrobe. If you plan to put two UK singles in one room for siblings or guests, you will need a larger room than that.
Should one adult choose the Wish 3000 in a UK single or a UK small double?
The UK single suits you if your room is tight or you sleep fairly still. If you like to spread out, the UK small double is 30cm wider than the UK single and the same length, which gives you noticeably more room to turn. We suggest at least 2.4m x 2.8m for the UK small double.
Is a UK single Wish 3000 long enough for a tall adult?
The UK single is 190cm long, the same length as the UK small double and the UK double. If you are tall enough for your feet to reach the end, the UK king is 10cm longer than the UK single, but it is also 60cm wider, so it needs a much larger room: we suggest at least 2.7m x 2.9m for the UK king.
