At 26cm deep, the Hypnos Natural Luxury pairs its natural fillings with Hypnos's ReActive 8-turn pocket springs, each spring responding independently to you and your partner. It comes in nine sizes, from a UK Single up to an Emperor. Hypnos is an NBF-Approved Manufacturer, and the mattress meets the BS7177: 2008 fire resistance standard. It suits sleepers who want a traditional, breathable feel, although anyone after a plush, sink-in surface may find medium firm a little too supportive.

Why should you choose this mattress?
If you sleep warm, this is a strong candidate. The wool and cotton fillings help regulate body temperature, and the eOlus fibres create a breathable layer that, unlike foam, doesn't hold onto heat or sweat. The fillings are also 100% recyclable, made without harsh chemicals, so there are no end-of-life disposal issues. Support comes from the ReActive 8-turn pocket springs, which sense the comfort needs of each sleeper independently, useful if you and a partner differ in weight. Yes, it's a real spend, but you're paying for natural materials and a 10-year Hypnos guarantee.
Key features & layer details
Pure Belgian Damask Cover
A breathable Belgian damask fabric tops the mattress. It lets air move through the sleep surface, which helps the natural fillings below do their temperature work.
Wool
Wool gives a soft, cushioned feel, which means gentle give at the surface before you reach the springs. It suits those who prefer a traditional, natural mattress.
Cotton
Cotton helps regulate body temperature through the night. It also adds a degree of support alongside its natural comfort.
eOlus™ Fibres
These fibres offer resilient body support while letting air and moisture pass through easily, so you get a soft, foam-like feel without the heat retention foam can bring. Made without harsh chemicals, the fillings are 100% recyclable with no end-of-life disposal issues.
ReActive™ 8-Turn Pocket Springs
Each spring has 8 turns and works independently, sensing the exact comfort and support needs of you and your partner. In practice that means vertical pressure is spread smoothly, giving total spinal and body support.

Best suited for?
Warm sleepers
Wool and cotton fillings help regulate body temperature, and the eOlus fibres let air and moisture pass through, so heat and sweat are less likely to build up.
Couples
Each ReActive 8-turn pocket spring works independently, so two people of different weights can each get support suited to them without feeling the other move.
Eco-conscious buyers
The fillings are 100% recyclable and made without harsh chemicals, which means no end-of-life disposal issues when the mattress eventually needs replacing.
Back sleepers
Medium firm support from the pocket springs spreads vertical pressure smoothly, giving the spine and body steady support while you lie flat.
Allergy sufferers
Natural wool and cotton fillings under a breathable Belgian damask cover suit anyone wanting a traditional mattress made without harsh chemicals.
If you love a soft, enveloping feel, this medium firm build may feel a little unyielding, particularly for lightweight side sleepers. If you prefer memory foam, this might not be the best choice either, as there's no foam here at all. And if a lengthy in-home trial matters to you, note that the retailer listing we sourced doesn't state one.
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 Natural Luxury mattress firm or soft?
It's medium firm. The wool and cotton fillings soften the surface a little, but the ReActive 8-turn pocket springs beneath keep the overall feel supportive. Most back and combination sleepers should get on well with it, although lightweight side sleepers may find it slightly too firm.
How deep is the Hypnos Natural Luxury mattress?
It's 26cm deep. That's a substantial build, so check your fitted sheets will stretch to accommodate it, particularly if you're moving from a shallower mattress.
Does the Hypnos Natural Luxury mattress have a guarantee?
Yes, it comes with a Hypnos 10-year guarantee, as listed on the MattressNextDay product page. Note that no trial period is stated on that listing, so ask the retailer about returns before ordering.
What sizes does the Hypnos Natural Luxury come in?
Nine sizes: UK Single, Small Double, Double, King, Super King and Emperor, plus EU Single, EU Double and EU King.
Is the Hypnos Natural Luxury good for hot sleepers?
It's a sensible pick. The cotton filling helps regulate body temperature, the Belgian damask cover is breathable, and the eOlus fibres let air and moisture pass through rather than trapping heat the way foam can.
