Layer Details
- Pillow Top. A plush stitched-in pillow top filled with wool, cotton and cashmere, which means a soft, cushioned surface without needing a separate topper. The natural fibres also help regulate temperature, useful if you tend to sleep warm.
- Pocket Springs. Up to 5,000 pocket springs that move independently of one another, which means support is targeted to your pressure points rather than spread evenly. It also helps limit motion transfer, so a restless partner is less likely to wake you.

- A small footprint in a crowded room: At 3ft x 6ft 3in, the UK single leaves space for a desk, a wardrobe and toy storage in a child's bedroom without the bed taking over the floor.
- A softer surface for one: The stitched-in pillow top gives a cushioned feel from the first night, which means a teenager or single adult gets a plush surface without buying a separate topper.
- Support that follows a growing body: The pocket springs respond individually, so a lighter child and a heavier teenager both get support where their hips and shoulders press down.
- Cooler for warm sleepers: The natural fibres in the pillow top breathe better than synthetic foam, which helps if the single goes in a small, warm box room.
- A comfortable guest bed: In a spare room that also works as an office, a UK single gives visitors a proper hotel-style bed while leaving room for a desk and chair.
- Check your frame first: At 38cm deep, this mattress is tall for raised frames, so confirm your bunk or cabin bed's maximum mattress depth before ordering.
This size suits you if...
You're furnishing a child's or teenager's bedroom that also has to fit a desk and wardrobe, you sleep alone in a compact room and prefer a softer surface over firm support, or your spare room doubles as a study and needs a guest bed with a small footprint.
Consider another size if...
You share the bed with a partner most nights, or you want a firm feel. For two sleepers we'd recommend the UK double instead, and we suggest at least 2.6m x 2.8m for the UK double.

Can I put a Serenity 5000 UK single on a bunk bed or mid sleeper?
Be careful here. The Serenity 5000 is 38cm deep, which is tall for a raised frame, and a deep mattress can bring the sleeping surface too close to the top of the safety rail. Check the maximum mattress depth your bunk, cabin or mid sleeper maker specifies before buying. On a standard single frame or divan, the depth is no problem.
Will a Serenity 5000 single fit in a box room?
Very likely, yes. The UK single measures 90 x 190cm, and we suggest allowing at least 2.1m x 2.8m of floor space so you can get in and out comfortably and still open drawers or a wardrobe. In a small room, the tall 38cm build does make the bed look a little more substantial than a slim single.
Do standard single fitted sheets fit the Serenity 5000 UK single?
Probably not. At 38cm deep, the Serenity 5000 needs deep fitted single sheets, and standard-depth ones tend to ping off the corners. The width and length are the usual 90 x 190cm, so a standard single duvet at 135 x 200cm fits fine. If you're kitting out a child's room, buy the deep sheets at the same time.
Is the Serenity 5000 in a UK single good for a teenager?
It suits most teenagers who like a softer, cushioned feel. The medium feel and pillow top are comfortable for side sleeping, and the springs keep support where their weight sits. A teenager who prefers a genuinely firm mattress will likely find it too soft. The stitched-in pillow top can't be flipped, so rotating it is the main upkeep.
Should I choose a single or a double Serenity 5000 for a guest room?
If your guests are usually on their own, or you need room for a desk, the UK single makes sense. For couples staying over, the UK double is 45cm wider and gives 67.5cm each for two sharing. We suggest at least 2.6m x 2.8m for the UK double, against 2.1m x 2.8m for the UK single.
