Layer Details
Cover
A soft, woven viscose cover sits on top. Viscose is smooth and breathable, so the surface feels gentle against bedding rather than clammy.
Comfort fillings
Beneath the cover sit generous natural fillings of British wool and alpaca wool. Wool helps regulate temperature, which means it can feel warmer in winter and cooler in summer than synthetic fillings.
Mini Pocket Springs
A layer of small, individually cased springs adds comfort close to the surface. These respond to lighter pressure, giving soothing relief at the shoulders and hips.
Pocket Springs
The main support comes from individual springs encased in cloth pockets. Each one adapts to movement separately, so support is distributed to each part of your body rather than the whole bed tilting when your partner turns over.

Key benefits
- Leaves room for everything else: At 90cm wide, the UK single leaves space for a wardrobe, a desk and toy storage, so a small bedroom still has somewhere to play or study.
- Two beds can share one room: If siblings share, or you want a guest room with two separate beds, the narrow footprint makes a pair of UK singles with a walkway between them more realistic.
- Breathable fillings for a warm child's room: British wool and alpaca help regulate temperature, which means a teenager in a small, stuffy bedroom is a little less likely to wake up overheated.
- Springs that respond to a lighter body: The mini pocket springs near the surface react to gentle pressure, so a smaller frame still gets some give at the shoulders and hips.
- Fits under a sloping ceiling: In a loft conversion where only a narrow strip has full headroom, the UK single slots into spaces a wider mattress simply wouldn't.
This size suits you if...
You're buying for a child or teenager who needs a proper, supportive bed without losing floor space, or you're furnishing a compact spare room or study. It also suits you if you sleep alone and want natural fillings in a size that fits a small room comfortably.
Consider another size if...
You share the bed with a partner, or you sprawl and want more width. 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
Is the Sleepeezee Centurial 01 4500 UK single a good mattress for a teenager?
For many teenagers, yes. The UK single is the standard one-person size, and the medium feel suits most back and combination sleepers. The wool and alpaca fillings also help in a warm bedroom. A very light child who prefers a soft, sink-in surface may find a medium a touch firm, though.
Will the Centurial 01 4500 UK single fit a bunk bed or mid sleeper?
The 90 x 190cm size matches standard UK single frames. The thing to check is depth. This mattress is 26cm deep, and raised frames such as bunks, cabin beds and mid sleepers often set a maximum mattress depth for the guard rail to work safely. Check the frame maker's guidance before buying.
How much room do I need for a Sleepeezee Centurial 01 4500 single?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk around the bed and open a wardrobe door, and still fit a desk in a child's room or a spare room that doubles as an office.
Can two people share a UK single Centurial 01 4500?
We wouldn't recommend it. The UK single is designed for one sleeper. For two people, the UK double gives 67.5cm each and the UK king gives 75cm each. We suggest at least 2.6m x 2.8m for the UK double and 2.7m x 2.9m for the UK king.
Should I get the UK single or UK small double Centurial 01 4500 for a guest room?
Pick the UK single if you want two separate beds or the room is tight. The UK small double is 30cm wider and the same length, which gives a single guest more space to spread out. We suggest at least 2.4m x 2.8m for the UK small double.
