Product Overview

Experience legendary cooling comfort and a cradling memory foam sensation, with the Dormeo® S Plus Evolution mattress featuring unique patented Octaspring® technology. Thicker than the standard S Plus mattress, the extra depth and 50% more memory foam makes this a softer, plusher option.

Find your own perfect comfort with the unique interchangeable dual firmness S-shaped core and enjoy completely personalised sleep.

The S Plus Evolution mattress diminishes tossing and turning, increases blood circulation and aids muscle regeneration whilst you sleep. Unlike other mattresses, the high quality Dormeo® Memory Foam is sewn directly into the cover, giving both individual sleepers and partners the most comfortable night’s sleep imaginable.

Unique S-Shape Layer

Inspired by the human body and the natural S-Shape of the spine, the S-Plus mattress is designed to provide unparalleled sleep comfort thanks to the innovative layer of Octaspring technology running through the heart of the mattress.

Complete Customisation

Based on 15 years of collaboration with engineers and research on the needs of more than 8 million customers, the result, the S Plus has been designed to be the first 100% personalised mattress offering over 30 comfort combinations*. 

1. Choose your Side

The smartly connected cores, personal to each side of the mattress, can be quickly and easily interchanged independently of one another making the S Plus the risk-free choice for couples with different sleeping preferences.

2. Choose your Comfort

Simply unzip the cover and flip your side of the mattress to choose between two between two unique Ecocell™ foam densities. Either the softer side normally suited for side sleepers, or the firmer side often preferred by back sleepers.

3. Choose your Support

Rotate your mattress core head to toe to find your preferred side of the unique S-shaped Octaspring® layer. Have the Octasprings closer to your neck and shoulders for more adaptability and more bounce, or simply rotate the mattress horizontally adding distance between the Octaspring layer and your neck and shoulders for more solid support under your shoulders.

Body Zoned Octaspring Technology

The Octaspring® is a next generation, patented sleep technology, which delivers up to 8x greater ventilation compared to traditional foam, offering a cooler, fresher night’s sleep, while providing incredible comfort and support.

Whilst the unique Octaspring® technology offers unrivalled breathability, the individual Octaspring® springs are arranged in different firmness levels, which create customised body support zones that are beneficial to correct spinal alignment for a better night’s sleep.

Next Generation Ecocell™

Our uniquely breathable Ecocell™ foam – the Dormeo® difference, encases the unique Octaspring® tube technology. Ecocell™ is a next generation foam designed to be permanently elastic with a 3-dimensional cellular structure, providing efficient air circulation and support where you need it.

Anti-bacterial, Anti Dust Mite

A luxurious quick drying Climalite Silver cover tops off the S Plus, wicking away moisture to keep the mattress fresh, whilst the Clean Effect treatment delivers anti-bacterial, anti-dust mite and anti-static protection.
