Extra firm with orthopaedic benefits

Taking orthopaedic support to new heights, this mattress is incredibly firm. For heavier people, this will mean your hips and shoulders don't 'dip' too far into the mattress surface, helping to keep your spine properly aligned. The extra firm reflex foam material contours your unique body shape, providing personalised support at every point of contact. This mattress is perfect for those who prefer to sleep on top of their bed rather than 'in' it.

Hypoallergenic and highly breathable

Hypoallergenic properties also make this an exceptional mattress for allergy sufferers, while enhanced airflow keeps your sleeping environment fresh and clean. A breathable knitted cover is soft to the touch and further encourages air circulation to prevent overheating.

Rolled and boxed for convenience

Arriving vacuum-packed, rolled, and boxed to your door, this mattress is easily maneuvered to your room of choice. Whether you need to get it up some narrow stairs, around tight corners or need to keep it in storage for a short while, this rolled mattress makes everything easier.

Features

Reflex Foam

Reflex Foam conforms to the shape of your body, offering a comfortable night's sleep, with tailored support to help improve your spinal alignment and posture.

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.

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.

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.

Turnable

The mattress has fillings on both sides. Double-sided mattresses need to be turned regularly to keep them in good condition.

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 - 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.
