Assessed from JAY-BE's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you're a hot sleeper or you've been put off by the sinking feel of foam, this is one to consider. The fillings are 100% foam-free, and the open-cell structure of the e-Fibre encourages airflow and helps moisture evaporate, which means less of that clammy, overheated feeling overnight. The green credentials are genuinely strong too: Jay-Be is a Global Recycled Standard certified manufacturer, independently audited as zero-to-landfill, and the fabric is OEKO-TEX certified, free from harmful chemicals. Materials are hypoallergenic and vegan-friendly, with a natural salt-based fire retardant rather than a chemical treatment. Yes, at 21cm it's a slimmer build, but the deep sprung core still provides evenly distributed support, and the price is honest for what you get.
Key Features & what's inside
- Cover/Fabric. A deep-quilted knitted fabric that's OEKO-TEX certified, which means it has been tested and shown to be free from harmful chemicals. The quilting adds a soft, cushioned surface feel from the moment you lie down.
- Comfort Layer. Extra-soft Advance e-Fibre with an open-cell structure that encourages airflow and helps moisture evaporate, so heat is less likely to build up around you. It's made from recycled PET bottles, with a minimum of 70% recycled content.
- Support Core. A deep sprung core that provides evenly distributed support across the mattress. Springs respond to pressure more quickly than foam, giving a slightly bouncier, more traditional feel.

Who's it NOT for?
If you love the slow, cradling sink of memory foam, this isn't it: the all-fibre-and-spring build gives a springier, more traditional feel. Its medium firmness may also feel a little soft for heavier sleepers who prefer firm support, and at 21cm it's shallower than some deep divan-style mattresses.

Is the Jay-Be Ryze mattress foam free?
Yes. The fillings are 100% foam-free, combining breathable Advance e-Fibre with a deep sprung core. That means better airflow than a typical foam boxed mattress, which you'll notice as a cooler, drier feel overnight.
How firm is the Jay-Be Ryze mattress?
Jay-Be describes it as medium firmness. That suits most sleepers, although anyone who prefers a very firm surface, or a heavier person needing extra support, may find it a little soft.
What is the Jay-Be Ryze mattress guarantee?
It comes with a 10-year guarantee from Jay-Be, which is reassuring at this price point.
How deep is the Jay-Be Ryze mattress?
It's 21cm deep across all sizes. Dimensions are Single 90x190x21cm, Small Double 120x190x21cm, Double 140x190x21cm and King Size 150x200x21cm. Standard fitted sheets should work fine, but it's slimmer than some deeper mattresses.
Is the Jay-Be Ryze mattress good for allergies?
The materials are hypoallergenic and vegan-friendly, the fabric is OEKO-TEX certified as free from harmful chemicals, and the fire retardant treatment is a natural salt-based one rather than a chemical coating. A sensible choice for allergy-prone sleepers.
