The Octasmart® Plus 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 mattress are hundreds of 9cm Octasprings® which work together to support and cradle every inch of your body, 3-dimensionally adapting to alleviate pressure from the back, hips & 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.

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

Octavent™ Air system - Our 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 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.

Smart Zoning - 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.

Not suitable for use with an electric blanket as this can alter the performance of the mattress.
