Dormeo S Plus Evolution Memory Foam Mattress Review

The biggest downside of memory foam is breathability and that is a well-known fact. Heat retention and lack of breathability are the reasons why hot sleepers used to avoid memory foam products, and even those who are not hot sleepers were reluctant to buy something containing memory foam. Many sleep companies have worked to overcome these problems and most have made progress, but Octaspring technology developed by Dormeo has gone a step further than all.

Springs are much more breathable than memory foam and then sleep experts came up with the idea to make memory foam springs, so we got Octaspring technology. Thanks to this technology we get 5 to 8x better breathability compared to classic foam. But that’s not all, because Octaspring springs are also body-zoned. This means that the foam springs of different firmness levels are implemented in the mattress, to provide unique support for every part of the body.

Octaspring technology would not be anywhere near as effective as it is, if it is encased in traditional memory foam which would again impair the circulation of the air. That is why Dormeo has launched another new type of foam on the market – Ecocell.

Ecocell foam has a 3D cellular structure so it is very breathable and encases Octaspring springs. Ecocell foam is not only made to be breathable, but it is very elastic, so it provides great support. According to the manufacturer, Ecocell is permanently elastic, so durability is top-notch.

Memory foam mattresses are generally a great choice for allergy sufferers because memory foam is not a suitable environment for dust mites and other allergens. And this mattress is additionally treated, so Clean Effect treatment makes it anti-bacterial, anti-dust mite and anti-static. All in all, we don’t expect you to have any allergy problems when sleeping on it.

We are sure that couples will give this mattress an A + when it comes to motion isolation. They will experience zero movement for several reasons. Memory foam is great at motion insulation plus memory foam is sewn directly into the cover, so motion transfer is zero. Individual Octaspring springs also absorb motion and since both have their own part of the mattress, couples will sleep peacefully even if one of the partners is a restless sleeper.

When you look at the spine, it has an S-shape. That’s why this mattress has an S-shape foam layer that is designed to follow the natural curvature of the spine, to provide perfect support. This is something that most other mattresses do not have and it is especially important for back sleepers, who will find it easy to maintain spinal alignment throughout the night.

The Dormeo S Plus mattress was the first mattress on the UK market that you could personalise 100%, and you can do the same with the Dormeo S Plus Evolution Memory Foam mattress. You have dozens of combinations available, more precisely, over 30 combinations, if you buy any size other than Single. The Single size offers slightly fewer combinations, but also more than enough.

The first thing you can do is have each of the partners in bed customise their side, independently of the other side. All you have to do is unzip the cover and choose which foam density you want. The choice will probably depend on your sleep position. Also, you can rotate the core and thus choose between more bounce or more support.

This mattress certainly does not belong to the group of extra deep mattresses, but it is not necessary for every mattress to be extra deep. Hybrid mattresses are usually deeper than memory foam ones, and the industrial average for memory foam mattresses is 20cm, so this model is a few cm deeper than average. That will be enough for people with higher BMI too and people of average weight usually can’t even tell the difference between 23 and 28 cm for example.

If you are looking for a softer, plusher option then this is the right choice for you. It is a medium-soft firm, although due to Octaspring springs and other supportive layers, you will have the feeling that it is closer to medium-firm mattresses. On a firmness scale from 1 to 10, it is 4, but the feeling can be 5 as well. Because of this firmness, we recommend it to side and back sleepers. Side sleepers exactly need this firmness to be able to sink and thus avoid shoulder pain.

We always advise customers to choose a mattress that has at least a 5-year warranty, because the mattress is not something that should be changed often. When a mattress comes with a 10-year warranty it’s great, and when it comes with a 18-year warranty like this one, then you know you’ve bought your mattress for the next two decades.

We expected Dormeo to offer a 100-night trial, but a risk-free 60-night trial is enough. It takes you about a month to get used to the mattress and after that, you have another month to be 100% sure you want to keep it.
