Jay-Be Ryze Sprung Quilted e-pocket 800 Mattress in a Box

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. It's fairly priced for what you get.

Warm sleepers
Open-cell comfort layers, a 3D Mesh ventilated border and a foam-free build give heat plenty of routes out, so you should stay cooler overnight.

Eco-conscious buyers
The Advance e-Fibre layer contains at least 70% recycled content, the fabric is OEKO-TEX certified, and it is made in the UK by a zero-to-landfill manufacturer.

Couples
Each of the 800 pocket springs moves independently, which reduces motion transfer so you are less likely to be woken by a restless partner.

Combination sleepers
Medium firmness and individually moving pocket springs that adapt to your body's contours suit a range of positions as you shift through the night.

Allergy sufferers
The OEKO-TEX certified fabric and moisture-wicking Advance e-Fibre top layer help keep the mattress feeling fresh, in a build with no foam at all.

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. If you prefer sleeping on a very firm mattress, this might not be the best choice either.

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 an affordable starting price. 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.
