The Dormeo Octasmart Deluxe Double Mattress combines three next-generation sleep technologies into one smart mattress:

Luxurious Memory Foam
 - A top layer of the highest quality open cell memory foam moulds perfectly to your unique shape for blissful comfort, adapting to, and cradling your entire body.

Octaspring® technology - At the heart of the topper are hundreds of 4cm Octasprings® which work together to support and cradle every inch of your body, 3-dimensionally adapting to alleviate pressure from the back, hips and shoulders. Every single Octaspring® comfort point adapts to your body weight and releases pressure across the extra sensitive support points, improving comfort and providing better sleep quality.

Signature Ecocell® Foam - A bottom layer of our signature Ecocell® foam, with a 3-dimensional permanent cell structure, offers a great supportive base.

The Octavent™ Air system is designed to make your topper naturally more breathable, aimed to helping you fall asleep faster, and sleep deeper for longer. This patented system harmonises award-winning Octaspring® aerospace technology with a smart performance cover, together allowing cool air to circulate inside the topper and hot air to escape.

Like Sleeping on clouds, the hundreds of comfort pockets built into the smart-performance cover will make you feel like you are sleeping on tiny clouds. It brings extra freshness to the topper allowing better air circulation and letting hot air escape.

Different firmness Octaspring® springs are arranged in 3 body zones to provide customised support for your back, with more support for your hips and shoulders which allows your spine to comfortably take its natural shape.

Safe for you, smart for the planet, the Dormeo Octasmart Deluxe Mattress has been designed to leave 50% less environmental footprint, as the toppers can be 100% recycled. Octasmart® products are free from harmful chemicals and emissions and are certified by OEKO-TEX certificate.
