The Cooflex® Hybrid ICE Mattress uses both pocket springs and cool gel memory foam to provide a superior night's sleep. The foundation of over 800 individually wrapped pocket springs, which each move independently, provides bespoke, targeted support for each part of your body. They also work to create unique 'sleeping zones', meaning that each occupant of the bed is resting on their own independent sleep surface. This allows movement within the bed without your partner feeling that movement through the bed.
On top of the pocket spring core is a thick layer of next-generation cool gel-infused memory foam. It provides all the benefits of memory foam, but also helps to maintain optimum body-temperature. This means not only cloud-like comfort and pressure-relieving support, but also a cool & fresh slumber.
The Hybrid ICE mattress comes vacuum packed, rolled and boxed. This allows you to transport with ease to your room of choice. Once unpackaged, the mattress will be ready to use within 4 hours (although the final 'feel' will not be at its best until around 48 hours!).
Buy with confidence knowing that Hybrid ICE mattress ships with a 5-year guarantee from Coolflex®.

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.
Cool Gel Memory Foam
Cool Gel Memory Foam enhances pressure relief and support, while also improving comfort for a better nights sleep. Cool Gel Memory Foam has the added benefit of being better at regulating body temperature than standard memory foam, so you won't feel too hot in warmer months.
26cm Depth
This mattress is approximately 26cm 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.
Reinforced Edges
The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.
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.
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.
Vegan Friendly
This product is made from materials that are 100% free from animal by-products.
Fire Resistant - Low Hazard
This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.
- Best of both worlds - cooling gel memory foam and pocket springs
- Perfect medium firm feel - ideal for all sleeping positions
- Arrives vacuum packed, rolled & boxed for easy transport to your bedroom
- Backed by a 5-year manufacturer's guarantee
- No movement transfer between sleepers

Instantly relieved the pain in my hip. Very comfortable and relaxing.Not too sure yet on the cooling effect, as may have been hampered by having one of the many bugs that are going around. But I think it is promising.
