Description

The Octasmart Premium Mattress takes the best elements of the support offered by pocket springs and the comfort provided by memory foam to create a new sleeping experience. Octaspring® technology offers adaptive and reactive support, 24 hours a day, seven days a week. To heighten the effect of sleeping on clouds, the Aerocell® foam offers sumptuous cushioning, given a firm foundation by a layer of Ecocell® foam. The Octavent™ Air System delivers next-generation temperature regulation, making your Octasmart Premium Mattress eight times more breathable than many of its standard counterparts. If a good night’s sleep has become something of a stranger, then the Octasmart Premium Mattress could be the reintroduction you’re looking for.

Breathable, supportive, cool, and comfortable, the Octasmart Premium Mattress sees sleep technology striding into the 21st Century. However, with the environment in mind, the mattress is 100% recyclable and uses 50% less material in its production than others. Sleep has never felt so good.

Beat the warm weather

If you run hot at night, the Octasmart Premium Mattress is designed to keep you cool, even when the weather is unseasonably warm. The unique Octavent™ Air System behaves like a series of air pumps, removing warm, humid air created by moisture and body temperature and drawing in cool, clean, dry air. The result is a cooling effect that means your new mattress is eight times more breathable than others and can help to reduce the temperature between the covers by up to 3°C. Free from chemicals, this system makes the mattress perfect for those who want to sleep deeper, for longer.

Space-age springs

Octasprings® are the next step in reactive and responsive support. While they're inspired by traditional pocket springs, they're made from specially-engineered memory foam. Crafted into lattice-like coils, they offer as much support as their metal cousins with the added ability to react immediately to changes in bodyweight, pressure, and movement. Used in aircraft seats, they've been individually nested to create five zones of body support, so your spine is kept in perfect alignment, and the weight is taken from pressure points, such as the ankles, knees, elbows, and shoulders.

Sleep in comfort

While support is important, you can't get a good sleep if the element of comfort is missing. The Octasmart Premium Mattress uses Aerocell® foam to ensure your downtime is supremely comfortable. Aerocell® foam boasts a permanently elastic quality, allowing it to comfort and cushion every part of your body. With a firmer Ecocell® layer underneath, this mattress offers a sleep experience like no other.

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.
