Layer Details
Pillow top
A plush pillow top with 2cm of soft foam beneath the surface. It gives a cushioned, softer-feeling top without changing the medium firm rating.
CoolGel foam
A 3cm CoolGel layer that contours gently to your body and disperses heat. That means pressure-relieving comfort with less heat build-up.
Pocket spring core
1000 individually pocketed springs with up to 2000 mini pocket springs. Each spring moves on its own, which gives a supportive base that follows your shape.

Key benefits
- Fits a compact room: We suggest allowing at least 2.1m x 2.8m of floor space, which means a box room or study can take this bed and keep a desk or wardrobe.
- Helps in warm small rooms: The 3cm CoolGel layer is designed to disperse heat, which helps a teenager or student sleeping in a small room where the air can feel a little stuffy.
- Easy for guests to settle into: The pillow top gives a soft, cushioned surface that most guests take to quickly, while the medium firm pocket spring base underneath keeps them supported.
- Simple to dress: A standard single duvet (135 x 200cm) fits, so kitting out a child's bed or spare room needs nothing unusual beyond deep fitted sheets.
- Turning handles for rotation: It's single-sided, so you rotate it head to toe rather than flip it, and the turning handles give you something to grip when you do.
This size suits you if...
You sleep alone, or you're furnishing a teenager's room or a spare room with a standard bedstead or divan, and you want a cushioned top over a medium firm spring base without giving up the floor space a bigger bed would take.
Consider another size if...
You need it for a bunk bed or mid-sleeper with a low depth limit, or you share the bed. For two sleepers, we'd recommend the UK double, which gives 67.5cm each; allow at least 2.6m x 2.8m.

FAQ's
Will the SleepSoul Heaven Cool Gel 3000 UK single fit a bunk bed or mid sleeper?
Possibly not. The UK single is 30cm deep, and raised frames usually set a maximum mattress depth so the guard rail stays high enough to be safe. Check the frame maker's limit before buying. If the figure is lower than 30cm, this mattress is better kept for a divan or bedstead at floor level.
What size room do I need for a UK single SleepSoul Heaven Cool Gel 3000?
We suggest at least 2.1m x 2.8m for a UK single. That leaves space to walk around the bed and fit a small wardrobe or desk, which matters in a child's bedroom or a spare room that also works as a home office.
Is a UK single long enough for a tall teenager?
The UK single measures 90 x 190cm, the same length as a UK double. If your teenager is tall and their feet already reach the end of the bed, the UK king is 10cm longer, although it needs far more floor space than a box room usually offers.
What sheets and duvet fit a UK single pillow top mattress?
A standard single duvet (135 x 200cm) fits this mattress well. For fitted sheets, choose ones with deep enough pockets to cover a 30cm depth, because a pillow top mattress this tall can pull shallow single sheets off the corners overnight.
Can two guests share a UK single SleepSoul Heaven mattress?
No, a UK single is a one-person bed. For a guest room, two UK singles side by side give each guest their own space. If you'd rather have one bed, the UK single is 45cm narrower than the UK double, and we suggest at least 2.6m x 2.8m for the UK double.
