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, £549 to £1,249 is a real spend, but you're paying for natural materials and a 10-year Hypnos guarantee. There's no stated trial period on the retailer listing we sourced, which is one thing to check before you buy.
Key Features & what's inside
- 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.

Who's it NOT for?
If you love a soft, enveloping feel, this medium firm build may feel a little unyielding, particularly for lightweight side sleepers. Memory foam fans should look elsewhere too, 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.
Hypnos Natural Luxury Mattress
View all mattresses
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. Prices range from £549 to £1,249 depending on the size you choose.
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.
