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.

Key benefits
- Room to spread out alone: The UK small double is 30cm wider than the UK single, which means you can sleep diagonally or starfish without an arm dropping off the edge.
- Keeps floor space in smaller rooms: Being 15cm narrower than the UK double, it leaves a little more clearance for a wardrobe door or a bedside table in a tight bedroom.
- Steady support for a visiting couple: The individually cased springs limit motion transfer, so two guests sharing for a weekend are less likely to wake each other when one turns over.
- Cooler sleep in a small room: Wool and alpaca layers help regulate temperature, useful in a compact bedroom or loft conversion where warm air tends to collect.
- Easy frames and bedding: At 4ft wide it is a standard UK size, so finding a frame is straightforward, although the 35.5cm depth calls for deep fitted sheets.
This size suits you if...
You sleep alone, you like to stretch out, and your bedroom is at least 2.4m x 2.8m but would feel cramped with a full double, or you are kitting out a guest room or loft conversion where couples stay occasionally rather than every night.
Consider another size if...
You share the bed every night, since two adults will feel short of space. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
What room size do I need for a Sleepeezee Centurial 03 in a UK small double?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk round the bed and open drawers. If your room is smaller than that, measure your door swing and any sloping loft ceilings before ordering, as a 35.5cm deep mattress on a frame sits fairly high.
Is the Centurial 03 7000 small double big enough for a teenager who has outgrown a single?
For most teenagers, yes. The UK small double is 30cm wider than the UK single and the same length, so they gain real sideways room without the bed taking over the floor. The medium firm feel suits most back and side sleepers, although heavier sleepers wanting a distinctly firm surface may prefer more resistance.
Can a couple sleep on the Sleepeezee Centurial 03 small double for a weekend?
For occasional stays it works well. Yes, 120cm is snug for two adults, but the pocket springs reduce motion transfer, so a restless guest is less noticeable to their partner. For couples sharing every night, the UK double gives 67.5cm each and is the more comfortable long term choice.
Will a Centurial 03 7000 UK small double fit a loft conversion bedroom?
Often it fits better than a full double. It is 15cm narrower than the UK double, which can free up enough width to stand beside the bed under a sloping ceiling. The wool and alpaca layers also help if the loft room runs warm in summer.
