Description

The leaders of sustainable sleep technology, JAY-BE have created the Jay-Be Benchmark S3 Memory Eco Friendly Mattress. With impressive support and comfort properties, this mattress is ready to enhance your sleep quality as soon as possible.

Expert orthopaedic support

A deep e-Spring™ core provides targeted orthopaedic support to your body, adapting to your movements throughout the night. This spring unit evenly distributes your weight over the surface of the mattress for a weightless feel. The medium-firm feel you'll experience is ideal for back, side, and front sleepers alike, especially if you're looking to sleep 'on' your bed rather than 'sink in' to it.

Foam-free memory e-Fibre™ cradles your body

Clever e-Fibre™ layers cushion your body in comfort and are highly breathable to provide a refreshing feel, while foam-free memory e-Fibre™ fillings contour to your unique body shape, offering personalised comfort. The padded border of this mattress ensures you can stretch out and enjoy the entire surface, as well as increases its lifespan.

Features

e-Spring™ Core

Sturdy support that evenly distributes your weight over the entire surface, providing a weightless feel.

Memory e-Fibre™

A foam-free, eco-friendly alternative to traditional memory foam, this highly breathable material contours your body for personalised pressure relief.

20cm Depth

This mattress is approximately 20cm deep.

Knitted Cover

This luxurious soft knitted cover is breathable, which helps to keep the sleeper at an even temperature all night long.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

Vacuum Packed & Rolled

Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully over time, usually being comfortable enough to sleep on after 48 hours.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

Hypoallergenic

Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

Vegan Friendly

This product is made from materials that are 100% free from animal by-products.

100% Foam Free

Free from harmful VOC emissions and uses a natural salt solution for fire retardancy, rather than harsh chemicals.

High Density Eco-Insulator

This eco-friendly layer prevents an uncomfortable 'spring feel'. You won't feel the springs digging into you, you'll just feel their supportive properties!

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Low Hazard

This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.

Additional features

Made by an NBF-Approved ManufacturerPeace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation.
