Hypnos describes the Denhome Luxury Comfort as medium, a feel that suits most sleepers, although lightweight side sleepers may find it a touch firmer than expected. Inside, 1200 six-turn pocket springs sit beneath layers of British wool and cotton, which means the mattress can adjust to your body temperature and wick away moisture rather than trapping heat. It comes in eight sizes, from a UK Single up to an Emperor, plus two EU sizes. Mattress Online offers a 100-night trial and a 10-year guarantee, which gives you real time to decide.

Why should you choose this mattress?
This is a mattress for people who care where their materials come from. The wool is Responsible Wool Standard certified, the Solotex padding is made from recycled plastic, and Hypnos holds a Royal Warrant from His Majesty King Charles III. The natural fibres do practical work too: wool and cotton are breathable, which means less overheating if you tend to sleep warm. Three rows of firmer springs around the border give edge support, so you can sit on the side or sleep near the edge without feeling like you might roll off. Yes, the starting price is a serious spend, but the construction and the 10-year guarantee listed by Mattress Online help justify it.
Key features & layer details
Cover
A blend of cotton, viscose and damask fibres with a chemical-free fire retardant treatment, which means it meets fire safety standards while staying kind to your skin. It's a soft, traditional-feeling surface rather than a synthetic one.
Comfort layer
Solotex padding made from recycled plastic sits just beneath the cover. It creates the cushioned initial feel you notice when you first lie down.
Wool filling
British wool, certified to the Responsible Wool Standard, acts as a natural insulator. Its breathable structure adjusts to your body temperature, so you're less likely to wake up too hot or too cold.
Cotton filling
Natural cotton fibres wick away moisture and help regulate temperature through the night. If you're a hot sleeper, this layer works alongside the wool to keep things fresh.
Support system
A core of 1200 ReActivePro six-turn pocket springs responds to each part of your body independently, which means your partner's movements are less likely to disturb you. Three rows of extra durable springs around the border firm up the edges.

Best suited for?
Warm sleepers
Breathable wool and cotton layers wick away moisture and adjust to your body temperature, which means you are less likely to wake up too hot.
Eco-conscious buyers
Responsible Wool Standard certified British wool and Solotex padding made from recycled plastic suit anyone who cares where their mattress materials come from.
Couples
Each of the 1200 pocket springs responds independently, which means your partner's movements are less likely to disturb you, and firmer border springs help you use the full width.
Combination sleepers
A medium feel that suits most sleepers, plus three rows of firmer edge springs, lets you move around and sleep near the edge without feeling unsupported.
If you want the contouring, hug-like feel of memory foam, this traditional pocket spring build won't give you that. It's also a stretch at a premium starting price if you're furnishing a guest room, and anyone hoping for a genuinely firm, orthopaedic-style surface should look elsewhere: Hypnos rates this as medium.
Save on an earlier or ex-display model

FAQ's
How firm is the Hypnos Denhome Luxury Comfort mattress?
Hypnos describes it as medium, though you may see it listed as medium firm elsewhere. In practice that means a balanced feel that suits most sleeping positions, and at least one owner reported it felt slightly firmer than they expected, so err on the softer side of your expectations.
Does the Hypnos Denhome come with a trial period?
Mattress Online lists a 100-night trial with this mattress, along with a 10-year guarantee. Those are the retailer's own terms rather than a Hypnos-wide promise, so if you buy elsewhere, check that seller's trial and returns policy before ordering.
What sizes does the Hypnos Denhome Luxury Comfort come in?
Eight sizes are available: UK Single, Small Double, Double, King, Super King and Emperor, plus EU Double and EU King.
Is the Hypnos Denhome good for hot sleepers?
It should be. The fillings are British wool and natural cotton, both breathable fibres that adjust to your body temperature and wick away moisture, and the pocket spring core allows air to move through the mattress in a way solid foam can't.
How is the Hypnos Denhome delivered?
Mattress Online offers free delivery to most of mainland England and most of Scotland, Wales and Northern Ireland, with a two-hour time slot and weekday next day delivery available. Room of choice delivery and old mattress removal are both available for an extra charge. These are the retailer's terms, not the brand's.
