Layer Details
- Pillow Top. A deep pillow top filled with cool gel memory foam, which means a cushioned surface that actively draws heat away from your body. It helps regulate your temperature through the night rather than letting warmth build up.
- Cool Gel Memory Foam. This layer adds pressure relief and support, moulding to your shape for a more comfortable night. It regulates body temperature better than standard memory foam, so hot sleepers get the contouring without the heat.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, which means support and pressure relief exactly where your body needs it. It also helps limit motion transfer if you share the bed.
- Knitted Cover. A soft, breathable knitted cover that lets air move through the surface. That helps keep you at an even temperature all night long.

- Leaves floor space free: At 3ft x 6ft 3in, the UK single leaves room for a desk, wardrobe and toy storage in a child's bedroom without the bed taking over.
- Cooler sleep for teenagers: Gel memory foam in the pillow top draws heat away from the body, which means a teenager in a small, warm bedroom is less likely to wake up hot.
- Firm support for growing bodies: The firm, orthopaedic feel keeps older children and teens well supported, although very light younger children may find the surface a little firm on hips and shoulders.
- Pairs neatly in shared rooms: Two UK singles suit siblings sharing a room or a guest room set up for two friends, with each sleeper on their own spring unit.
- Fits a spare room office: A UK single sits against one wall of a study that doubles as guest space, keeping the rest of the room usable for work.
- Deep build to check against frames: The 32cm depth gives a plush, full feel, but it reduces guard rail height on bunks, cabin beds and mid sleepers, so measure first.
This size suits you if...
You're kitting out a child's or teenager's room where the bed has to share space with a desk and storage, you sleep alone and tend to run warm, or you want a supportive guest bed for a spare room that also works as an office.
Consider another size if...
You share the bed every night or want space to stretch out. 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.

Is the SleepSoul Coolology 3000 single too deep for a bunk bed?
It may be. At 32cm, the UK single is deeper than many mattresses designed for bunks, cabin beds and mid sleepers, and a deep mattress lowers the effective height of the guard rail. Check the frame maker's maximum mattress depth before ordering, and if the frame falls short, choose a slimmer mattress for the top bunk.
What size room do I need for a UK single Coolology 3000?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open drawers, which matters in a child's room where the bed also has to share space with a wardrobe and desk.
Is a UK single Coolology 3000 long enough for a tall adult?
The UK single is 190cm long, the same length as the UK double. If you're tall and your feet reach the end, the UK king is 10cm longer; we suggest at least 2.7m x 2.9m for the UK king.
Is the Coolology 3000 single too firm for a young child?
SleepSoul describes it as firm, which suits older children and teenagers who want solid support. Very lightweight children, especially those who sleep on their side, press into the surface less, so they may find a UK single of this mattress a little unyielding on hips and shoulders.
Is the SleepSoul Coolology 3000 a good single for a guest room?
For a spare room that doubles as a study, a UK single keeps the footprint compact against one wall. The firm feel and gel foam suit most adult guests, and two UK singles side by side let you host a pair of friends who would rather not share a bed.
