What the Sleep Expert thinks...

"If you struggle with overheating at night, this is one of the most effective options in the range. The cooling gel layers genuinely make a difference, helping you feel fresher from the moment you lie down. At the same time, the firm spring system keeps your spine aligned, so you’re getting both temperature control and proper orthopaedic support in one mattress"

Description

The solution to hot, sleepless nights, the SleepSoul Cooler Ortho 4000 Series Pocket Gel Mattress is here to keep you cool and comfortable all night long. With thick layers of cool gel memory foam, you'll instantly feel the cooling effects of this refreshing mattress as soon as you touch it!

Orthopaedic support for better posture

Firm pocket springs keep your body wonderfully supported, with orthopaedic effects. By moving independently, these springs are able to precisely target your pressure points, keeping your spine, hips, and shoulders perfectly aligned. Memory foam layers provide further support by cushioning your body and molding to your unique curvature. This breathable foam responds to your movements, ensuring you're properly supported and comforted at every point of contact.

Actively draws heat away from your body

Generous layers of thick cool gel memory foam also cushion your pressure points, but their most exciting feature is the cooling sensation they provide. Actively drawing heat away from your body, this specially engineered material prevents overheating and encourages a night of deeper sleep, with your body naturally dropping in temperature as you sleep. It's well-known that coolness can help to reduce inflammation, so coupled with orthopaedic support, this mattress encourages a truly blissful night's sleep.

Instant cooling sensation

A cool feel knitted fabric cover enhances breathability, as well as offers an instant cooling effect as soon as you get into bed. This incredible technology is impressively cool to the touch, not just drawing excess heat away from your body, but actively emitting a cold sensation to refresh your entire body. Perfect for hot sleepers, those going through menopause, or anyone who enjoys a cooler sleeping environment, this cover provides fast-acting freshness.

Features

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.

Cooler™ Fabric Cover

Active cooling properties provide an instant cool sensation. Highly breathable for a fresher feel.

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.

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.
