Does a hybrid mattress completely free of memory foam sound interesting to you? If the answer is yes, then the Silentnight Just Breathe Eco Comfort Hybrid Mattress may be the right choice for you. We found that idea interesting, so we tested it, and the following are all our observations about this product.

Silentnight is a well-known brand so it has a lot to live up to. They have produced many mattresses of different variations, with something for everyone. However, the cheaper price range might make some customers a bit skeptical. We wanted to put their Just Breathe mattress to the test to find out whether you get the breathability they describe, along with being eco-friendly and for a bargain!

Let's take a look into our full review.

Advantages

Good for front sleepers
It's most suited to those who sleep on the front due to the mattress firmness.
Side-handles-pro
Handles on the side
This design makes the mattress easy to put on your bed frame and move around when needed.
comfortable-pro
Fairly comfortable
There's a bouncy and springy feel to it which makes the firm mattress more comfortable.

Disadvantages

Some motion transfer
Due to the bounce of the mattress, you're likely to feel some motion transfer.

You cannot remove the cover, making the maintenance a bit trickier.

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 firm mattress and therefore enjoy an undisturbed night's sleep.

We wouldn't be surprised if Silentnight characterised 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 like this mattress, as will most back sleepers. It definitely wouldn't be a top recommendation for those who are side sleepers because they're likely to find that their pressure points don’t sink in enough to encourage spinal alignment.

To summarise, it's for:

What do we use this product for?

This mattress is part of the Just Sleep range as a Just Breathe mattress. Its purpose is to give you enhanced breathability for a comfortable sleep, regulating your body temperature with the breathable layer and additional features. On top of this, we use this mattress to give us a support system that provides enhanced spinal alignment so your body can stay in the best sleeping position. Although it focuses on giving you great support, you'll also experience comfort through the slight bounce it has.

The mattress is used for:

Features you should know about 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. Several sections of this mattress help it to be beneficial to your sleep and we want to show what a few of them can do.

Eco Comfort fibre layer​

The Silentnight Eco Comfort features several eco-friendly mattress variations and is named after its key feature: eco-friendliness. The Eco Comfort fibre 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. Having the eco comfort fibres makes the mattress better for those who are hot sleepers as it reduces excess heat and encourages constant airflow throughout the product.

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 support enhances spinal alignment, giving you a good posture and tailors to you 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 for you to sleep soundly. Overall pocket springs are superior compared to continuous coils.

24cm depth

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 isn't great, but due to the quality of the materials, it's 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.

Hypoallergenic soft knit 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's no need for unnecessary chemical treatments. An additional bonus is the attractive micro quilted finish of the knitted Coolmax cover. It's 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's 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 various ways over time. It is approved by Allergy UK.

365-night trial

We have previously criticised 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 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.

Review of Silentnight Just Breathe Eco Comfort Hybrid Mattress

Adam reviewing the Just Breathe Eco Comfort hybrid mattress by Silentnight

Now it's time for the main 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's 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's hypoallergenic, but there's no removable cover and therefore not washable so keeping it clean can take time.

One of the main downsides is the lack of pressure relief. The Just Breathe Eco Comfort Hybrid Mattress does not excel in edge support either – while there is some, it isn't the best we've experienced. The mattress comes with a 10-year warranty and a 1-year sleep trial so if you don't get a refreshing night's sleep, you can easily return it.

KEY FEATURES:

  • Size: Single, Double, King Size
  • Depth: 24 cm
  • Cover material: Polyester
  • Layers' material: Individual pocket springs and Eco fibre
  • Firmness: 8/10
  • Support: 8/10
  • Breathability: 9/10
  • Motion isolation: 6/10
  • Pressure relief: 5.5/10
  • Hypoallergenic: Yes
  • Removable cover: No
  • Care instructions: Wipe it down with a damp cloth
  • Warranty: 10-year warranty
  • Trial: A 1-year trial.

What we like about Silentnight Just Breathe Eco Comfort Hybrid Mattress

Silentnight's Hypoallergenic 3D fabric cover on the Just Breathe Eco Comfort 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.
  • I love that the design looks like an Oreo with cream sandwiched between two biscuits. It just gives it a more exciting aesthetic compared to others. Aside from the Oreo design, the casing does have a practical use. It has been made breathable by using mesh panelling around the sides. This reduces excess heat and keeps a continuous flow of air in and out of the mattress.

What we didn’t like about Silentnight Just Breathe Eco Comfort Hybrid 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-sprung 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.

Silentnight's customer service and company information

Delivery – When ordering, you get free shipping and a quick delivery time of 48 hours so you won’t need to wait around for weeks for your new mattress to arrive. It’s a reasonably priced product but if paying out a chunk of money in one go is too much, you can split the payment over several months.

Payment – The usual card payments are available when purchasing this mattress. Although, you do have the extra options of using PayPal or Klarna if you would prefer to spread your payment.

Online customer service – If you need help with anything, there’s a live chat online but it’s only available during working hours. This isn’t ideal for those wanting a fast response, so you can always drop us a comment and we can get back to you.

What makes this product better than some other similar ones?

The standout for this product is the price range for such a quality product. Other mattresses of similar quality are much more expensive (compare them with our new mattress comparison tool) but this one does exactly what it says. It's a durable option that comes with a long warranty so you know it'll last you a while without needing to be replaced.

Is the Silentnight Just Breathe Eco Comfort Hybrid Mattress eco-friendly and sustainable?

This specific mattress is eco-friendly as it is part of the Eco collection where all the products are made from recycled materials, such as plastic bottles. These recycled materials make up the eco-comfort fibre layer that can be found in the Just Breathe mattress. This also means the mattress can be recycled after use.

As a whole, Silentnight is undergoing changes to make them carbon-neutral by 2040. They choose to repurpose waste instead of dropping it at a landfill.

Silentnight, as a company, is trying to become more sustainable by:

How did we test the product?

Connie squeezing the edge of the mattress while laying on it

Here we will explain how we tested the mattress when collecting all the relevant information. With all our products we start with the following tests:

  • Visual inspection
  • Hands-on inspection
  • Measured tests

To test the Silentnight Eco Comfort Hybrid Mattress, there were specific tests we took to find out the quality of the product. This included:

Overall impressions of the product after the testing

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's a great mattress, of good quality and good value. It is denser and more supportive of your body weight. Most hybrid mattresses use memory foam but this one doesn't 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.

We can agree with the name of this mattress – it is breathable and does provide comfort. It hasn’t got any standout features, however, it’s definitely a great price for the advantages you receive.
