Why should you choose this mattress?
This mattress makes sense if you want natural materials without foam-heavy construction. Latex offers pressure relief and returns to shape quickly, which means you won't feel stuck in one position, while the wool and alpaca layers help regulate temperature. If you're a hot sleeper, that combination is genuinely useful. The dual spring system, 4500 full-size pocket springs plus 2500 mini springs, gives a more responsive, personalised feel than a single spring layer, and reduces motion transfer for couples. The medium feel suits most back and side sleepers, although heavier sleepers who prefer a firmer surface may want more resistance. It's a significant spend, but the depth, natural fillings and handcrafted UK construction go some way to justifying it.
Key features & 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.

Best suited for?
Warm sleepers
Wool and alpaca wool layers work together to regulate temperature, which means the sleep surface stays closer to comfortable through the night and across the seasons.
Couples
Two layers of individually cased pocket springs, 4500 full-size plus 2500 mini, reduce motion transfer, so a restless partner is less noticeable beside you.
Side sleepers
Latex offers pressure relief and returns to shape quickly, giving a medium feel with less of a sinking sensation when you lie on your side.
Back sleepers
The medium feel suits most back sleepers, and the dual spring system gives personalised support along your body rather than a flat, uniform surface.
Combination sleepers
Latex springs back quickly, which means you won't feel stuck in one position and can move more easily when you change position during the night.
With a premium starting price, this isn't a budget option, so if you're furnishing a spare room there are cheaper routes. The medium feel may be too soft for those who need a distinctly firm surface, and at 35.5cm deep you'll want to check your fitted sheets can cope.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Sleepeezee Centurial 03 7000?
The retailer product page describes it as medium. That suits most back and side sleepers who want support with some give, although if you strongly prefer a very firm surface it may feel a little soft for you.
How many springs does the Centurial 03 7000 have?
It contains 4500 traditional pocket springs combined with 2500 mini pocket springs, a total of 7000. Each spring is individually cased, which means support adapts to your body shape and movement transfers less across the bed.
Does the Sleepeezee Centurial 03 come with a trial?
Mattress Online offers a 100-night trial and a 10-year guarantee. These are the retailer's own terms rather than a manufacturer promise, so check the conditions wherever you buy.
Is the Sleepeezee Centurial 03 good for hot sleepers?
It should help. The pillow top is filled with natural alpaca wool and there's a separate wool layer beneath the latex, both natural insulators with good temperature regulating properties. It's a fully sprung design too, which tends to allow more airflow than foam-heavy builds.
What sizes does the Sleepeezee Centurial 03 7000 come in?
It's available in UK Single, Small Double, Double, King and Super King.
