Description

1278720-5063475047258

Features

3600 Pocket Springs

Pocket springs are springs mounted in their own separate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.

Staycool™ Gel

Staycool™ Gel helps to manage moisture levels within the mattress, which aids temperature regulation so you won't feel too hot in warmer months.

33cm Depth

This mattress is approximately 33cm deep.

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.

Pillow Top

Pillow top mattresses have the benefit of an additional pillow layer of plush fillings on the top of the mattress, which provides extra luxurious comfort.

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.

Made in The UK

This item has been manufactured in the UK.

Additional features

Knitted CoverThis luxurious soft knitted cover is breathable, which helps to keep the sleeper at an even temperature all night long.
Vegan FriendlyThis product is made from materials that are 100% free from animal by-products.
Made by an NBF-Approved ManufacturerPeace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation.
Fire Resistant - Low HazardThis product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.
