Assessed from the specification published by MattressNextDay, captured September 2026, and from regular price comparison across our UK retail partners.
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 & what's inside
- 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.

Who's it NOT for?
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 from price of £949 puts it beyond entry-level options.
Hypnos Purity Luxury Wool Mattress
View all mattresses
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. Prices range from £949 to £2,099 depending on the size you choose.
