Who is Silentnight Just Breathe Eco Comfort Hybrid Mattress for?​

Just Breathe Eco Comfort Hybrid Mattress is quite a firm mattress. Silentnight classifies it as medium/firm, and we agree. Of course, firmness depends on your body weight, as well as the base of the bed it is on. In general, nearly all people will experience it as a medium firmness mattress and therefore enjoy an undisturbed night's sleep.

We would not be surprised even if Silentnight characterized it as an orthopaedic mattress, due to the level of firmness and extra support. That's why it can be exactly what someone with a bad back or posture is looking for. The majority of those who prefer to spend their nights on their stomachs will also like this mattress. Most back sleepers may buy it too, while we are not so sure about side sleepers.

However, there is a possibility that if you are a side sleeper you will be able to use it comfortably, especially those with higher BMI, so they should take advantage of the trial period and learn about it first-hand.

Features you should know about Silentnight Just Breathe Eco Comfort Hybrid mattress​

To further comprehend why it is termed a hybrid mattress, we must first examine its distinguishing features and qualities.

Eco Comfort Fibre layer​

The Silentnight Eco Comfort series features several eco-friendly mattress variations and is named after its key feature: eco-friendliness. Silentnight is a company that makes a significant contribution to the preservation of the environment, although certainly not all of its products are sustainable because they are made of polyester. Silentnight is an environmentally friendly, Carbon+ neutral organization and they have signed up to the Climate Pledge committing to achieve Net Zero Carbon by 2040. Silentnight powers factories and offices from 100% renewable schemes.

The Silentnight Eco Comfort fibres layer featured in this mattress has now become part of over 80% of all Silentnight mattresses. Those sustainable fibres are made into 100% polyester fibres from recycled plastic bottles, and the main characteristic of the product is breathability. It is also a soft layer, but it can't offset the firmness of the springs, it just makes the mattresses a little cosier to sleep on.

1000 Pocket springs

The heart and soul of these Breathe mattresses is a pocket spring system. Silentnight's Mirapocket mattress pocket spring system is in charge of firmness and support. The system consists of 1000 individually nested pocket springs. The springs are 18 cm tall. The zoned springs enhance spinal alignment, giving you a good posture and tailored support whilst you sleep.

Why does it matter that pocket springs are individually nested? This is very important for several reasons. When the springs are fully separated, as in this case, then the motion isolation is complete. Targeted support is also achieved and fabric pockets absorb sound, making the mirapocket mattress completely silent with easy movement – the mattress truly does offer a silent night. Overall pocket springs are superior compared to continuous coils.

24cm deep

While 18 cm tall pocket springs are of above-average height, the overall height of the mattress falls within the average for hybrid mattresses. This implies the Silentnight Eco Comfort layer and knitted cover are together only 6 cm thick, which is not great, but due to the quality of the materials, it is enough.

The average thickness of hybrid mattresses on the UK market is 25 cm, and Silentnight has followed that trend. You won't have a problem finding fitted sheets and you certainly won't have to look for extra deep fitted ones. This thickness is suitable for all base types including a slatted bed frame, although the mattress does not have an anti-slip base.

Hypoallergenic 3D fabric cover

If the Silentnight Eco Comfort fibres layer is a huge plus for Silentnight in terms of being environmentally friendly, the polyester cover is a minus. The positive side is that the covering material is naturally flame retardant, so there is no need for unnecessary chemical treatments. An additional bonus is the attractive micro quilted finish of the knitted Coolmax cover. It is good at letting heat out, providing extra ventilation and moisture regulation. This is not always a characteristic of polyester, making this cover better than many other polyester covers.

The knitted cover is not removable so you can only wipe it clean, however, it is recommended you should use a mattress protector and bed sheets. Even if you don't eat or drink in bed and don't have pets, you might still stain the mattress in a variety of ways over time. It is approved by Allergy UK.

365-night trial

We have previously criticized Silentnight more than once because of the short trial period, which made them lag behind the competition in that category. Now it's time for praise. They have extended the trial period to six times longer and now it lasts 365 days for this mattress.
They have overtaken most of the competition that offers 100 and 200-night trials. However, the trial period remained without a cash-back guarantee. If you don't like the product, you can exchange it for another one, but you won't receive your money back. Now we are waiting for Silentnight to change that policy as well.

5-year warranty

Ultimately, the Silentnight Just Breathe Eco Comfort Hybrid Mattress comes with a 5-year warranty, which we must say is not a terrific offer. It is not a terrible offer either, but you can get mattresses in this price range with 10-year or even lifetime warranties, those far outweigh the 5-year guarantee provided by this one.
On the plus side, the guarantee covers everything necessary and the mattress appears to be sturdy enough to outlast the warranty, so you should never have to use it. Still, we would rate a highly longer warranty.

Review of Silentnight Just Breathe Eco Comfort Hybrid Mattress

Now it's time for the main Silentnight mattress review of the Just Breathe Eco Comfort Hybrid mattress by Silentnight. This is an unconventional hybrid mattress which, instead of a combination of memory foam and springs, combines springs and an Eco Comfort fibre layer made from recycled plastic bottles. On a firmness rating scale of 1 to 10, this mattress is about an 8 for an average-weight sleeper. As such, it is suitable for stomach and back sleepers who need a lot of support instead of a mattress that sinks under pressure. It is a single-sided mattress and gives the impression of durability.

The pocket springs, Silentnight Eco Comfort fibres, and 3D fabric cover combination provide a very breathable mattress – a suitable choice for hot sleepers. It is hypoallergenic, but the cover is not removable and therefore not washable. One of the main downsides is the lack of pressure relief. Just Breathe Eco Comfort Hybrid Mattress does not excel in edge support either. The mattress comes with a 5-year warranty and a 1-year trial so if you don't get a refreshing night's sleep, you can return it.

What we like about Silentnight Just Breathe Eco Comfort Hybrid Mattress

• A non-orthopaedic mattress that has orthopaedic-like characteristics such as medium firm support for perfect spinal alignment.
• The Silentnight Eco Comfort fibre layer of the mattress is made from recycled materials (plastic bottles) instead of memory foam is a huge boost for this product on a sustainability scale.
• Tests have shown that this is a fairly sturdy and durable mattress.

What we didn’t like about Silentnight Just Breathe Eco Comfort Hybrid mattress

• The knitted cover is not removable, so the mattress protector is a must-have to keep it in the best condition.
• It is too firm to provide significant pressure relief.
• Side sleepers would appreciate at least one more Silentnight Eco Comfort layer or a memory foam to make this a softer mattress.

The common problems with Silentnight Just Breathe Eco Comfort Hybrid mattress & how to solve them

The common problem side sleepers have with the Silentnight Just Breathe Eco Comfort Hybrid mattress is its medium firmness. It is too firm, but an even bigger problem is the lack of pressure relief and support on the pressure points, which is especially important for side sleeping. The solution is to add a soft, memory foam topper to provide extra support and pressure relief. But is it worth buying a topper for a brand-new mattress that is not cheap at all?

The problem that most pocket spring mattresses and spring mattresses have, in general, including this one, is edge support. But we don't consider this a major problem because the support is not terrible and most people don't sleep on the very edge of it anyway.

Overall impressions of the product after the testing

Silentnight is one of the UK's largest and most trusted sleep manufacturers. It is also classified among Superbrands. Our expectations from their products are always very high. After using this mattress, we believe that this is an excellent hybrid eco-friendly mattress, although certain characteristics differ from what we usually expect from hybrid mattresses. It is a great mattress, of good quality and good value. It is firmer and more supportive because there is no memory foam, which means no off-gassing. 

On the other hand, pressure relief and edge support are at a lower level. That's why we give an 8 to Just Breathe Eco Comfort Hybrid mattress, and we are sure that a large number of customers will be very satisfied with their new mattress after having a good night's sleep.
