Product Overview

Just as your phone and TV have become smart, now so can your sleep. Using the latest innovation in sleep technologies, Octasmart® mattress toppers are powered by patented multi-award winning Octaspring® aerospace technology. Transform your mattress into the most comfortable and coolest bed of your dreams.

A layer consisting of hundreds of individual Octasprings® at the heart of the Octasmart® Mattress Topper evens out the lumps and bumps in your old mattress and adapts to your body. A patented Octavent™ Air System with a smart performance cover allows your bed to breathe through the night, plus 3 smart body zones create optimal support for your back, shoulders and hips - that’s what we call smart comfort engineering!

Smart Comfort at Heart

The Octasmart® Mattress Topper combines three next-generation sleep technologies into one smart topper:

1. Supportive Aerocell Foam

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

2. 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 & 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.

3. Our Signature Ecocell™ Foam

A bottom layer of our signature Ecocell™ foam, with a 3-dimensional permanent cell structure, offers a great supportive base. As well as transforming your old mattress, the topper can be used on your guest best, sofa bed, futon or even directly on the floor.

Octavent™ Air system

Our Octavent™ Air system makes your topper naturally 8 times more breathable, cooling your bed temperature by 3°C, 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.

Safe for you, Smart for the Planet

Designed to leave 50% less environmental footprint, our toppers can be 100% recycled. Octasmart® products are free from harmful chemicals and emissions and are certified by OEKO-TEX certificates.
