Features

EcoFoam®

EcoFoam® is a unique material made from 100% recycled and re-engineered foam, resulting in a much ‘greener’ product and with a reduced carbon footprint. EcoFoam® is resilient and durable & naturally dust mite resistant, offering excellent body support.

14cm Depth

This mattress is approximately 14cm deep.

Waterproof Cover

A breathable waterproof cover that is just as comfortable as it is practical.

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.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

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.

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.

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Source 5

Domestic Flammability Rated BS 7177 - Source 5 fire retardant. Ideal for use in commercial environments such as Hotels, Universities, Holiday Camps, Retirement Homes, etc.

Additional features
