Description

Breathable, supportive, supremely comfortable, and 100% recyclable, the Octasmart Premium Deluxe Mattress has it all. Using innovative technology and space-age design, the mattress is packed with revolutionary Octasprings® for tailored and responsive support. The comfort comes courtesy of the deep and cushioning layer of premium quality, bolstered by a layer of patented Ecocell foam. With the Octavent™ Air System helping to keep you at the perfect temperature for a deep and refreshing night’s sleep, your bed will become your favourite place in the home.

The Octasmart Premium Deluxe Mattress is for those who want to transform their sleep experience. With perfect levels of cushioning and support, combined with an outstanding onboard climate control system, a deep and indulgent sleep needn’t be a thing of the past.

Sleeping smart

The Octasmart Premium Deluxe Mattress uses the next step in sleep technology in the form of Octasprings®. While they're as strong, responsive, and adaptive as traditional pocket springs, they've been made from specially-engineered memory foam. Crafted into lattice-like coils, they are fully breathable, helping to keep the mattress fresh and the sleeper cool at night. The mattress has been designed to offer extra support to where it's needed most, so the Octasprings® have been arranged in five different smart zones, each with its own levels of firmness. By keeping the hips and shoulders supported, the spine can achieve its natural shape, helping to minimise back pain while taking the weight from pressure points, such as the knees, ankles, and elbows.

Keeping cool

The Octavent™ Air System has been developed to ensure the sleeper is kept at the perfect temperature throughout the night. The system acts like hundreds of tiny air pumps, drawing cool, dry air into the mattress and discharging air that's become warm and humid as the result of moisture and body temperature. As a result, the Octasmart Premium Deluxe Mattress is eight times more breathable than others and can reduce the temperature between the sheets by up to 3°C. Ideal for those who run hot at night.

Peerless comfort

To enhance its cloud-like comfort, the Octasmart Premium Deluxe Mattress uses open-cell memory foam to cushion and contour your whole body. This is supported by a layer of patented Ecocell® foam which offers consistent elasticity thanks to its three-dimensional cell structure. In addition, this mattress is wrapped in a smart performance cover, which sports hundreds of comfort pockets for that ‘sleeping on air’ feeling.

Features

Octasprings®

Breathable memory foam springs of different firmnesses are arranged in up to 8 body zones to provide unmatched levels of support, flexibility and comfort across your entire body for a healthy, restful sleep. Built up in layers, individual Octasprings® dynamically conform to the contours and movements of your body in all sleeping positions.

Ecocell®

Ecocell® is a unique, next generation foam designed to be permanently elastic with a 3 dimensional cellular structure, providing efficient air circulation and support where you need it. Ecocell® has been especially developed to guarantee point adaptable support and remain permanently elastic. A three-dimensional cellular structure allows the material to breathe. While you sleep, the elasticity of Ecocell® foam reduces the painful pressure points that can sometimes cause you to toss and turn during the night.

Memory Foam

Originally designed by NASA, Memory Foam moulds to your body, giving orthopaedic support and superb comfort. It also helps to overcome the pressure points of the body.

Ecocell® Foam Support Layer

A layer of signature Ecocell® Foam, with a 3-dimensional permanent cell structure, provides both a breathable and moisture wicking support layer.

Removable Cover

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.

Hypoallergenic

Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
