Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want natural materials without giving up the responsiveness of springs. The Talalay latex core is naturally bouncy, which means turning over feels easy rather than like wading through foam, and two fleeces of wool help regulate temperature if you tend to sleep warm. The eOlus™ fibres in the top layers are made from recycled plastic bottles, a small sustainability point that also adds support. Certifications back it up: Responsible Wool Standard, National Bed Federation approval and BS7177: 2008 fire resistance. Mattress Online, currently the only listed retailer, offers a 100-night trial on it, so you can change your mind if the medium feel doesn't suit.
Key Features & what's inside
- eOlus™ and Solotex™. Two layers of synthetic fibres sit at the top: plush eOlus™ fibres made from recycled plastic bottles add a firmer feel and extra support, while Solotex™ provides a cushioning comfort layer. Both are breathable and durable, which means the surface should hold its feel over time.
- Wool. Two fleeces of natural wool sit above the latex. Wool is naturally temperature-regulating and lets air flow freely, which means less overheating on warm nights.
- Latex. The core is natural Talalay latex, an extremely springy material that gives the mattress its bouncy feel. That resilience is good for relieving built-up pressure, particularly around hips and shoulders.
- ReActivePro™ 6-turn pocket springs. At the centre are 1200 ReActivePro™ 6-turn pocket springs that mould to your shape for personalised support. The 6-turn design responds quickly and bounces back, which means support follows you as you move.

Who's it NOT for?
If you want a firm, unyielding surface, the Hypnos medium rating and springy latex probably won't suit you. It's also a stretch for tight budgets: at £1,269 upwards, there are far cheaper hybrids. And if you dislike bounce and prefer the slow, sinking feel of memory foam, latex will feel too lively.
Hypnos Witney Latex Supreme Mattress
View all mattresses
Is the Hypnos Witney Latex Supreme firm or medium?
Hypnos rates it as medium, although you may see it listed elsewhere as medium firm. In practice the latex core gives a supportive but springy feel, so it suits most sleepers who want balance rather than an especially hard or soft surface.
Does the Hypnos Witney Latex Supreme come with a trial?
Mattress Online, the retailer listing this mattress, offers a 100-night trial. That's the retailer's own offer rather than a Hypnos policy, so check the terms wherever you buy.
How long is the guarantee on the Hypnos Witney Latex Supreme?
It carries a 10-year guarantee from the manufacturer, which gives reasonable long-term reassurance on a mattress at this price.
What sizes does the Hypnos Witney Latex Supreme come in?
It's available in UK Single, Double, King, Super King and Emperor, plus EU Double and EU King. Prices range from £1,269 to £2,419 depending on size.
Is the Hypnos Witney Latex Supreme good for hot sleepers?
It should be a sensible pick. The wool layers are naturally temperature-regulating and let air flow freely, and latex tends to sleep cooler than memory foam, so hot sleepers are less likely to overheat.
