The Sleepeezee Centurial 02 6000 is described by the maker as medium in feel, which suits most sleepers who want support without a hard surface. At 31cm deep it has a substantial, hotel-style build, with UK Single up to Super King available. It sits at the pricier end, but the British wool and alpaca fillings, which help regulate temperature naturally, go some way to justifying that. Mattress Online lists it with a 100-night trial and a 10-year guarantee, though those are the retailer's own terms.

Why should you choose this mattress?
The main appeal here is the combination of two spring layers and natural fillings. Full-size pocket springs adapt to your movement and support each part of your body individually, while a layer of mini pocket springs sits above them, which means you get a cushioned, pressure-relieving feel at the surface rather than lying directly on the main support unit. British wool and alpaca fillings insulate and regulate temperature, so if you run warm at night this is a sensible pick over synthetic foams. It carries recognised reassurances too: National Bed Federation approved, handcrafted in the UK, and conforms to BS7177: 2008 for fire resistance. Yes, it costs more than entry-level pocket sprung options, but the materials are a cut above.
Key features & layer details
Cover
A soft woven cover forms the sleeping surface. It is the first thing you will feel when you lie down.
Comfort fillings
British wool and alpaca wool fillings sit beneath the cover, chosen for their natural insulative and temperature regulating properties. In practice, that means a surface that helps keep you comfortable across warmer and cooler nights.
Mini Pocket Springs
A layer of small, individually cased springs adds comfort and gentle pressure relief. These respond to lighter pressure than the main springs, so the mattress feels responsive at the surface.
Pocket Springs
The main support layer uses individual springs encased in cloth pockets that adapt to your movement. Each spring works independently, which means support is distributed to each part of your body rather than the whole surface moving as one.

Best suited for?
Warm sleepers
British wool and alpaca fillings insulate and regulate temperature naturally, which means you should stay more comfortable through the night than on a synthetic foam surface.
Combination sleepers
Individually cased pocket springs adapt to your movement, so changing position through the night should feel easy, with support following each part of your body.
Side sleepers
A layer of mini pocket springs sits above the main springs, giving a cushioned, pressure-relieving surface for shoulders and hips rather than lying straight on the support unit.
Couples
Each full-size spring works independently, so support is spread to each part of your body rather than the whole surface moving as one, and the size range runs up to Super King.
Back sleepers
A medium firm feel gives support without a hard surface, while the individually working pocket springs support each part of your body.
If you want a mattress you can rotate easily on your own, this may frustrate you: across owner reviews on Mattress Online it is described as heavy and needing two people to turn. Budget shoppers should also look elsewhere, given the premium starting price. And if you dislike any natural wool scent, be aware some owners mention a slight odour at first.
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
Is the Sleepeezee Centurial 02 6000 firm or medium?
The product page describes it as medium, so it should suit most sleepers, although some owners report it feels a little firmer than expected for the first few days before settling. If you need a genuinely firm mattress, this may be softer than you want.
Does the Sleepeezee Centurial 02 6000 come with a trial?
Mattress Online lists a 100-night trial, but this is the retailer's own offer rather than a Sleepeezee guarantee, and it requires buying a mattress protector from Mattress Online to qualify. If you buy elsewhere, check that retailer's terms, as they may differ.
How deep is the Sleepeezee Centurial 02 6000 mattress?
It is 31cm deep, which is a substantial build. Worth checking your fitted sheets before it arrives, as shallower sheets may struggle to stay on a mattress of this depth.
What sizes does the Sleepeezee Centurial 02 6000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King.
What guarantee does the Sleepeezee Centurial 02 6000 have?
Mattress Online lists a 10-year guarantee with this mattress. As that figure comes from the retailer's listing rather than Sleepeezee's own page, it is sensible to confirm the guarantee terms with whichever retailer you buy from.
