Experience cooling comfort and the cradling sensation of memory foam, with the Dormeo® S Plus mattress featuring unique patented Octaspring® technology. The S Plus is a mattress first - completely customisable personalised sleep! Make your sleep experience truly your own by choosing from a combination of different comfort and support levels thanks to a configurable S-shaped Ecocell core

No matter your preferences or how you sleep, the S Plus mattress can provide both individual sleepers and partners with their own great night’s sleep.

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 sleelpers, 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.

Rated 5 out of 5 by from Absolute comfort! This mattress is so comfortable I’m only sorry I didn’t get it sooner. Both me and my husband have slept soundly since getting it. We are not interrupted by each other’s movements and the mattress supports our backs according to our individual needs. Definitely recommend the pillows too.

Rated 5 out of 5 by from Fab mattress Purchased about 3 months ago now and we love it! It’s super comfy and brilliant that I can have a firm side of a mattress whilst my husband can have the soft side. No more bad backs for either of us and a great nights sleep is had by both. Highly recommend this matteess and well worth the money. It doesn’t sink in middle and there is no rolling together.

Rated 5 out of 5 by from Sleep on a cloud Not sure if a variable mattress is a gimmick but 60 day return made it worth a try. I am glad I did. Have suffered shoulder pain for some time, but no longer. Good nights sleep, no shoulder pain, result.

Rated 5 out of 5 by from 2 part reversible mattress for individual needs Bought memory fresh mattress 2019, fabulous comfort but for small double and decided it was not big enough, so donated to our son. Treated ourselves to the S plus and were not disappointed, so comfortable I have to prise myself out of bed to go for my morning swim. Would recommend Dormeo products to anyone needing a new mattress before any other product.

Rated 5 out of 5 by from Great mattress I bought the s plus mattress because the wife and I need different sleeping surfaces
Date published: 2020-01-26
Rated 5 out of 5 by from Wonderful! On the first night I felt like I sank into it. When I awaoke it felt like it was surrounding me and I felt nurtured, of all things. This is obviously silly, but that's what it felt like. I simply did not want to get up. These feelings lessened as the nights passed but it still feels wonderful, warm, comfortable. I had a similar mattress from the major competitor at several thousand pounds before and am astonished that this is even better. It is the best and most comfortable mattress I have ever had.

Rated 5 out of 5 by from Great Product Was a bit sceptical about the mattress as had seen it on one of the shopping channels but it has turned out to be just as all the adverts say. We unrolled it after it arrived & then a couple of days later put it on the bed and since then (2 months) we have had a good nights sleep, we also bought two pillows. We bought the mattress that you can alter to suit & we have one mattress one way & the other the other way, easy enough to change, just unzip the top cover, don't notice when one of us gets out of bed in the middle of the night either. Would thoroughly recommend this mattress.

Rated 5 out of 5 by from Great mattress Bought this for my grandson and his wife who haven’t been sleep8ng well. When I saw it I didn’t see how it could live up to other reviews, didn’t look any different to their previous mattress. But from the moment they slept on it they loved it, sleeping well and so comfortable. They love they can change the firmness on just one side if needed.
