How We Test

Our testing process


11 June 2024 5 min read

You need to make the most out of your 8 hours in bed, therefore, you need a good mattress! One of the mattresses that came to mind was the Silentnight Miracoil mattress, therefore, we've decided to test it out. Is this Silentnight Eco Comfort worth – does it offer good value for money? Well, let's find out together!

Who is Silentnight Miracoil Ortho mattress for?

Who can benefit from this Silentnight Eco Comfort mattress? Well, anyone, if we’re being completely honest. 

Silentnight Miracoil is one of those mattresses that seems to be a solid fit for anyone. It looks good, it's quite firm and supportive and it doesn't lack any important features. If we compare it to Silentnight Miracoil memory mattress – its cousin – it is a bit firmer due to orthopedic properties.

If we were to nitpick, we'd say heavier sleepers and stomach sleepers are the ones that this mattress was made for, but that's hardly all that this one is good for.

What do we use this product for?

Those in need of some extra firm feeling and support can benefit from this product in more than one way. Extra firm structure and support allow for a much more pleasant and comfortable experience for those that like to sleep on their stomachs or for those packing a few extra pounds. In addition, the ecocomfort fibre structure ensures you stay on the top of the clouds so you will feel nothing but the high quality comfort during your night's sleep.

Features you should know about the Silentnight Miracoil Ortho mattress

As we’ve previously mentioned, each product has a set of its own defining features and properties and Silentnight Miracoil is no different. As you're about to see, Silentnight's team of experts has come up with several, unique features to really set this one apart from the competition… See why sleepers call this mattress an extra firm mattress.

Miracoil springs

As this is a mattress type with an open coil system, the spring count is high in this product! The Miracoil spring system by Silentnight provides exceptional zoned support, superior spinal alignment, maximizes sleeping room, and decreases motion transfer for less partner disruption, making it perfect for couples, as well as restless sleepers.

The Miracoil spring system is different from the others in the way that it has a continuous length of coils ‘knitted' into a series of interwoven springs that are connected vertically rather than horizontally to provide better and firmer support for your or your partner's body.

Furthermore, Miracoil systems boast up to twice as many coils compared to the regular coiled mattresses, providing you with much better weight distribution and pressure relief.

Damask cover

The first comfort layer is this hand tufted Damask cover. Even though it is non-removable, the hand-tufted Damask luxurious cover on this mattress is truly something special. This is a high-quality, quilted damask fabric that ensures the most comfortable, slip and motion-free sleeping experience. This high-quality cover is the standard for all of Silentnight's mattresses.

The Damask fabric is just one of several layers of these mattresses. It is only when you put them all together that you are able to experience the quality of this mattress to the full extent. This brings us to our next point…

Fillings & materials

The Miracoil spring system's unique zoned design provides comfort and support for people of all shapes and sizes. Miracoil's unique shape has twice as many springs as a traditional circular spring system, offering additional pressure relief, edge to edge support for optimum sleep space, and zoned support right where you need it most. Therefore, you can also get rid of your back pain.

On top of that, memory foam layers ensure that you get the most comfortable sleeping experience. The top memory foam layer is 25 mm thick, which is just enough to properly contour your body and relieve some of the pressure from the usual pressure points like hips and shoulders.


Just like any other high-quality mattress, Silentnight Miracoil is hypoallergenic. Having a hypoallergenic cover is not only important if you’re suffering from allergies or perhaps asthma, as anyone can appreciate and enjoy a dust-mite and an allergen-free sleeping environment. This is most definitely one of the features that you should always look for in a mattress. It is scientifically proven that sleepers who sleep on hypoallergenic products have healthier and prolonged life.

As you already know, we’re looking at a non-removable, luxurious, quilted cover as the top sleep surface. What you don’t know is that the cover, as well as the rest of the mattress, has been treated with Purotex, a natural probiotic that helps combat almost all of the known allergens, ensuring the utmost sleeping experience. The product is verified by experts as hypoallergenic.

Review of Silentnight Miracoil Ortho mattress

a corner of Silentnight Miracoil Ortho mattress

If your goal is to find a reliable, durable, firm, orthopaedic, but still comfortable mattress to sleep on, then this one might just be the right for you. Silentnight Miracoil is specially designed to offer substantial support and fantastic spinal and full-body alignment, while still providing more than enough comfort and sinkage. The spring system offers great zoned support, which makes this one very good at equally dispersing body weight and relieving the pressure, even though it is on the firmer side of the spectrum.

Naturally, this orthopaedic mattress isn’t without its flaws. The quilted cover is non-removable, which makes this mattress very hard to clean, so we wouldn’t recommend breakfast in bed. Additionally, even though this one has some leeway and it does contour to your body nicely, if you’re lightweight and you sleep on your side – you might want to take a look at something different. In addition, the ecocomfort fibre ensures that the product is made in the sustainable way.

Finally, we have to mention that Silentnight Eco Comfort mattress offers a 60-night trial for this and every other mattress in their catalogue, as well as the 5-year warranty, for this one in particular.


  • Type: Pocket spring
  • Size: Single, Small Double, Double, King, Super King
  • Depth: 24 cm

  • Firmness: 8/10
  • Removable cover: No

Check these alternatives to Miracoil Ortho mattress

As in all our reviews, we have to suggest some of the alternatives. In case that the Silentnight Eco Comfort firm mattress doesn't do it for you, you can always look for an alternative that might. You can check our list with the best orthopedic mattresses or compare essential information on the top mattresses in the UK market with our new comparison tool.

If you want particularly a mattress for bad back, we have the guide as well. To make things easier for you, we’ve decided to present you with two alternative picks – Vesgantti Pro Hybrid and Silentnight 2000. Here’s a brief overview of both.

Vesgantti Pro Hybrid Mattress

Similarly to the Silentnight Miracoil, the Pro Hybrid from Vesgantti also combines springs with memory foam to ensure great support and comfort.

The Pro Hybrid is a multi-layered, pocket sprung/memory foam mattress with 7 zones of support, ensuring you feel comfortable and rested every time you fall asleep. But how does it differ from the Silentnight Miracoil? Well, there are two main areas of difference.

For one, this mattress is a bit softer. While it still clocks in as a medium-firm, it's still noticeably softer than the Miracoil. And if you're a side-sleeper and/or of a smaller build, this is quite significant!

The second key difference is the price. After all, if you're getting a Double, the Pro Hybrid is around 100+ pounds cheaper than the Miracoil. So, if you're more budget-oriented, this could be a better pick overall.

Silentnight Mirapocket 2000

Once again, we have a pocket sprung/memory foam mattress as an alternative option. Unlike Miracoil, Silentnight 2000 uses Mirapocket zoned spring system to ensure utmost support, pressure relief and comfort.

This one comes with 2000 individually nested springs and a 15 cm layer of memory foam on top of them. The mattress, combining all layers, offers 38 cm of depth, which is a lot!

Consider Silentnight Airmax Mattress Topper If You Are Buying Miracoil Ortho Mattress

As we’ve said, these Silentnight mattresses offer great support, but it is a bit on the firmer side. Therefore, a firm orthopaedic mattress topper could come in handy, especially if you are looking for an extra support.

More precisely, an Airmax mattress topper from Silentnight could just be what you need. Additionally, with an easily washable mattress topper, you don't have to worry as much about cleaning your mattress.

Don't forget to check out our Silentnight Airmax mattress topper review to learn more about it.

What makes This Ortho mattress better than some other similar ones?

What Silentnight Miracoil does much better than the rest of the products in a similar price range is that it keeps you properly aligned, supported and cool while you sleep. Those three are definitely the strongest points of this orthopaedic mattress, especially if you're on the heavier side and you struggle to find a mattress that's going to support your weight, but still, keep you cool and comfortable.

No customer has ever filled a complaint on the brand, nor this Silentnight Eco Comfort mattress whatsoever. The open coil system ensures super comfort with the help of eco comfort fibres, but also the appropriate support. The Miracoil springs keeps everything in place, with that touch of extra firm support that you need for an optimal night's sleep.

How did we test this Miracoil Ortho mattress?

As you already know, finding the perfect mattress isn’t easy. Silentnight Eco Comfort could easily be a perfect fit for your partner and a complete opposite to you and we’ve kept that in mind. When we test these products for our reviews, we try to do so as thorough and objective as possible, even though we both know mattress feel is purely subjective. Still, it is an ortho mattress (head to toe) so we know for sure it is going to be good for ortho sleepers who need a firm mattress.

Now, just because the feeling of a mattress is subjective doesn't mean that there is no good way to separate a good product from a bad one. Every mattress, regardless of the type or price point is defined by its key features, such as firmness, zoned support and edge support, pressure relief, ease of movement and motion transfer, breathability and cooling properties, durability, trial period, free shipping and finally, the warranty.

When we test these products, our team pays special attention to each of these features. We have to, if we wish to present you with a clearer picture of each product. Our team consists of several individuals of different body types and sleeping preferences which is key to delivering an objective verdict not only for this firm mattress but for all others. We pride ourselves on being thorough in our testing and being objective with our verdict, which is something you’ll notice in just a few moments.
