With a plush, cushioning pillow top, and orthopaedic, highly supportive pocket springs, the Premium Memory Hybrid Mattress is ready to offer you the proper night's sleep you've been dreaming of.

Orthopaedic pocket springs target key areas of the body

High tensile steel pocket springs are housed in individual fabric pockets, allowing them to move independently - a bit like piano keys - to adapt to your changes in weight distribution (your movement) throughout the night. This adaptability allows them to target intense support to key areas of your body, especially your shoulders and hips, which in turn helps to keep your spine aligned to reduce back aches and pains.

A cooler, fresher night's sleep free from overheating

To help keep you at the optimal sleeping temperature, a generous layer of Cool Gel Memory Foam actively draws heat away from the body for a fresher, cooler sleeping experience. This memory foam also gently moulds to your unique body shape, offering personalised pressure relief that helps to relieve tension at every point of contact. A plush pillow top layer acts as a built-in mattress topper, plumped with Comfort Foam layers which provide even more cushioning pressure relief.

An undisturbed night's sleep and a fuller sleep surface

Reinforced edges thanks to an outer layer of firmer pocket springs allow you to enjoy the full surface of the mattress without worrying about side-sagging. Maintaining the structure of the mattress and enhancing its durability, this 'no roll together' technology also gives you and your partner personalised sleeping zones, so you don't end up rolling towards the middle of the bed by accident.

800 Pocket Springs icon
800 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 icon
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.
32cm Depth icon
32cm Depth
This mattress is approximately 32cm deep.
Knitted Cover icon
Knitted Cover
This luxurious soft knitted cover is breathable, which helps to keep the sleeper at an even temperature all night long.
Orthopaedic Support icon
Orthopaedic Support
Designed to offer a firmer sleep surface, providing targeted support for your back and joints.
Reinforced Edges icon
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 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.
Vacuum Packed & Rolled icon
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 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.
Vegan Friendly icon
Vegan Friendly
This product is made from materials that are 100% free from animal by-products.
Fire Resistant - Low Hazard icon
Fire Resistant - Low Hazard

Customer Review Summary

Customers generally appreciate the quality and comfort of the product, often noting that it greatly enhances their sleep experience. Many reviews highlight the excellent support it provides, contributing to less discomfort during the night, which is especially beneficial for those with specific sleep needs. The durability and high-quality materials used in its construction have also received favourable mentions. However, some customers found it to be firmer than expected, which can be a double-edged sword—while it offers strong support, those preferring a softer feel may need some time to adjust. Overall, the product is well-regarded for its blend of comfort and practicality.
