Assessed from JAY-BE's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Breathability is the standout reason. Every layer here is designed with airflow in mind: open-cell comfort layers, a 3D Mesh ventilated border and a foam-free build, which means heat has plenty of routes out rather than building up around you. If you're a hot sleeper, that matters more than almost anything else. Sustainability credentials are unusually strong too. The Advance e-Fibre layer uses a minimum of 70% recycled content, the fabric is OEKO-TEX certified, and Jay-Be is a zero-to-landfill certified manufacturer made in the UK. The medium firmness suits most sleepers, although anyone wanting a plush, sink-in feel or a very firm surface should look elsewhere. From £224.23, it's honestly priced for what you get.
Key Features & what's inside
- Advance e-Fibre™. An extra-soft, deep-quilted top layer of Advance e-Fibre, which means a luxurious surface feel the moment you lie down. It also wicks moisture away to help keep the mattress fresh and regulate temperature.
- Breathable comfort layers. Open-cell comfort layers let air circulate freely through the mattress. In practice that means a fresher, more ambient sleep environment rather than trapped heat.
- 3D Mesh ventilated border. The border itself is made from ventilated 3D mesh, which gives warm air an escape route around the sides. It's a small detail that adds to the mattress's overall breathability.
- Deep Pocket Sprung core. 800 individual pocket springs adapt to your body's contours for tailored support. Because each spring moves independently, motion transfer is reduced, so you're less likely to be disturbed by a restless partner.

Who's it NOT for?
This isn't the mattress for you if you love the slow, cradling sink of memory foam, as it's entirely foam-free by design. At 23cm deep it's also a little slimmer than some, so if you prefer a tall, hotel-style mattress it may feel modest. Very firm-mattress fans should look elsewhere too.

Is the Jay-Be Ryze e-pocket 800 foam free?
Yes. Jay-Be describes it as 100% foam-free, using breathable fillings and an Advance e-Fibre comfort layer instead of foam. That's good news if you sleep hot, as foam tends to hold onto body heat, and this construction is built for airflow throughout.
How firm is the Jay-Be Ryze Sprung Quilted mattress?
Jay-Be lists it as medium firmness. That middle-ground feel suits most sleepers and sleeping positions, although anyone who specifically wants a very soft or very firm mattress may find it a compromise.
How many springs does the Jay-Be Ryze e-pocket 800 have?
It contains 800 individual pocket springs. Each spring moves independently, so the mattress adapts to your body's contours and reduces motion transfer, meaning less disturbance when a partner shifts position.
What guarantee comes with the Jay-Be Ryze mattress?
Jay-Be offers a 10-year guarantee on this mattress, which is a reassuring commitment at this price point. It also comes with free next working day delivery when ordered before 12pm.
Is the Jay-Be Ryze mattress sustainable?
It has stronger credentials than most. The Advance e-Fibre layer is made from recycled PET bottles with a minimum of 70% recycled content, the fabric is OEKO-TEX 100 certified, and Jay-Be is a Global Recycled Standard certified, zero-to-landfill manufacturer making the mattress in the UK using 100% certified renewable electricity.
