Features
3600 Pocket Springs icon
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 icon
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 icon
33cm Depth
This mattress is approximately 33cm deep.
No Need To Turn icon
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 icon
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 icon
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 icon
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 icon
Turning Handles
Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.
Hypoallergenic icon
Hypoallergenic
Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
