The Hypnos Purity Luxury Wool uses wool to regulate temperature and wick away moisture, which means fewer clammy nights if you tend to sleep warm. It's 26cm deep and sits at the premium end, but Hypnos is an NBF-approved manufacturer and the mattress carries a 10-year guarantee. It arrives flat rather than rolled and boxed, so the fillings aren't compressed in transit. Sizes run from UK Small Single right up to Emperor, plus EU sizes.

Why should you choose this mattress?
This is a mattress for people who want natural, breathable materials rather than foam. The ReActivePro™ 8-turn pocket springs respond independently to body movements, which means your partner's shifting shouldn't disturb you, and Triple Edge Protection™ keeps the perimeter supportive if you sleep near the edge. Above the springs sit Solotex™ cushioning for pressure relief, wool and cotton for temperature control, and an eOlus™ recycled fibre pad for resilience and airflow. It's hypoallergenic and fire resistant to BS7177: 2008. The medium firmness suits most sleepers, although those who prefer a very firm surface may want to look elsewhere. Yes, it's a real investment, but the materials and 10-year guarantee help justify it.
Key features & layer details
Cover
A damask cover made from breathable Belgian damask fabric. It lets air pass through rather than trapping heat at the surface.
Solotex™ cushioning
Layers of soft Solotex™ cushioning gently cradle the body, which means pressure relief at your hips and shoulders. This is the plush feel you'll notice first.
Wool and cotton fillings
Sumptuous wool fleeces from British sheep on Red Tractor assured farms work alongside responsibly sourced cotton. Together they regulate temperature and wick away moisture, a genuine help for hot sleepers.
eOlus™ comfort pad
An eOlus™ recycled fibre pad enhances resilience and airflow. It helps the comfort layers keep their shape over time.
ReActivePro™ pocket springs
An 8-turn pocket spring system with Triple Edge Protection™, engineered to respond independently to body movements. In practice that means adaptive support tailored to your shape and a firmer, more usable edge.

Best suited for?
Warm sleepers
Wool and cotton fillings regulate temperature and wick away moisture, which means fewer clammy nights if you tend to overheat in bed.
Couples
The ReActivePro™ 8-turn pocket springs respond independently to movement, which means your partner's shifting shouldn't disturb you during the night.
Allergy sufferers
Hypoallergenic construction using natural wool and cotton fillings suits anyone who wants a cleaner, more breathable sleep surface without relying on foam.
Combination sleepers
A medium feel with independently responding pocket springs gives adaptive support as you change position, with a firmer edge from Triple Edge Protection™ when you roll.
Eco-conscious buyers
Fillings include British wool from Red Tractor assured farms, responsibly sourced cotton and an eOlus™ recycled fibre pad, so the materials are natural or recycled.
If you like the contouring hug of memory foam, this traditional sprung feel won't give you that. Those who need a very firm or very soft surface should look elsewhere, as it's a medium. And if your budget is tight, the starting price puts it beyond entry-level options.
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 Hypnos Purity Luxury Wool mattress firm or soft?
It's listed as medium, which suits most back and side sleepers. If you're a heavier person who prefers a very firm surface, or a lightweight sleeper who likes to sink in deeply, it may not be the ideal match.
Does the Hypnos Purity Luxury Wool mattress come with a guarantee?
Yes, it carries a 10-year guarantee, which appears to be the Hypnos manufacturer's warranty as stated on the MattressNextDay listing. Hypnos is an NBF-approved manufacturer, which adds some reassurance about build quality.
Is the Hypnos Purity Luxury Wool mattress good for hot sleepers?
It's a strong choice. The wool and cotton fillings regulate temperature and wick away moisture, the eOlus™ pad promotes airflow, and the Belgian damask cover is breathable. Natural fibres like these tend to run cooler than foam-heavy designs.
Does the Hypnos Purity Luxury Wool mattress arrive rolled up?
No, it's delivered flat rather than rolled and boxed, so the natural fillings aren't compressed in transit. MattressNextDay lists free next-day delivery, though that's the retailer's own service offer rather than a Hypnos-wide promise.
What sizes does the Hypnos Purity Luxury Wool come in?
It's available in UK Small Single, Single, Small Double, Double, King, Super King and Emperor, plus EU Single, Double and King.
