Layer Details
- Cover. A soft woven viscose cover creates a silky smooth finish. It's the first thing you'll feel, and it sets a gentle tone for the layers beneath.
- Pillow top. An additional comfort layer filled with natural alpaca wool, which means a more luxurious feel underneath you. The alpaca also helps with temperature regulation, useful if you tend to overheat at night.
- Latex. Latex is incredibly durable and returns to its shape quickly, offering superior pressure relief. In practice, that means less of a sinking feeling and easier movement when you change position.
- Wool. A natural insulator with strong temperature regulating properties. It works alongside the alpaca layer to keep the sleep surface closer to a comfortable temperature year round.
- Pocket Springs and Mini Pocket Springs. 4500 traditional pocket springs are combined with 2500 mini pocket springs, each individually cased. This provides personalised support along your body and reduces motion transfer, so a restless partner is less noticeable.

- Leaves floor space free: At 90 x 190cm, or 3ft x 6ft 3in, it leaves room for a desk and wardrobe in a child's bedroom, and we suggest allowing at least 2.1m x 2.8m.
- Support shaped to one body: The 4500 pocket springs and 2500 mini pocket springs respond to a single sleeper's shape, which means a growing teenager's hips and shoulders are supported individually rather than sagging into a dip.
- Cooler in snug rooms: The wool and alpaca layers help regulate temperature, which is useful in a small loft conversion bedroom where warm air tends to collect under the sloping ceiling.
- Twin guest beds: Two UK singles side by side let a spare room host friends who would rather not share, and each guest gets the same medium firm surface.
- Check raised frames first: At 35.5cm deep it sits high, so on a bunk or mid sleeper you'll want to confirm the frame's maximum mattress depth and that the guard rail still clears the surface.
This size suits you if...
You sleep alone and want natural fillings in a compact bedroom, or you're furnishing a teenager's room or a guest room where two single beds make more sense than one double.
Consider another size if...
You share your bed with a partner most nights. 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 Sleepeezee Centurial 03 7000 UK single too deep for a bunk bed?
It may be. The mattress is 35.5cm deep, which is tall for most raised frames. Before buying, check the bunk or mid sleeper maker's maximum mattress depth and make sure the guard rail still sits comfortably above the sleeping surface. On a standard divan or bed frame the depth is no problem.
Will a UK single Centurial 03 fit a small bedroom?
In most cases, yes. The UK single measures 90 x 190cm, and we suggest at least 2.1m x 2.8m of floor space so you can still open a wardrobe and walk around the bed. That makes it a sensible option for box rooms, children's rooms and loft conversions with a narrow usable floor.
Will my teenager outgrow a UK single Centurial 03 7000?
Width is rarely the issue for one sleeper, but length can be for a tall teen. The UK single is 190cm long, and the UK king is 10cm longer. If height is a concern, we suggest at least 2.7m x 2.9m for the UK king, so check the room first.
Is the Centurial 03 7000 in a single a good choice for a guest room?
It suits a guest room you use regularly, especially with two singles for guests who prefer separate beds. For a room used a few nights a year, this is a premium mattress with natural fillings, so a simpler option may be the better use of your budget. Compare the prices listed on this page.
Do standard single fitted sheets fit the Sleepeezee Centurial 03?
Check the pocket depth before you buy. The mattress is 35.5cm deep, so look for deep fitted single sheets that list a pocket at least that deep. A standard single duvet, 135 x 200cm, fits the UK single without any trouble.
