If you've stumbled upon Dunlopillo Royal Sovereign Mattress, you're probably in the market for a high-quality, premium mattress that's going to last you for years. On paper, Dunlopillo Royal Sovereign Mattress should do just that, but is that really the case? Well, let's find out together.

Who is Dunlopillo Royal Sovereign mattress for?

Dunlopillo Royal Sovereign mattress is for anyone in need of a high-quality latex mattress. The 210mm latex core is a natural-based product that is eco-friendly and enough-supportive to be a good pick for all types of sleepers.

Dunlopillo Royal Sovereign Mattress is durable, resilient, responsive and completely noise free, allowing you to get a good night's sleep any time you lie down. Due to noise-free construction, it is the perfect match for couples as well.

Furthermore, if you're one of the many that suffer from allergies, an anti-allergenic mattress such as this one will go a long way for you.

What do we use this product for?

This mattress has been expertly engineered to contour individual profiles and movements, encouraging ultimate pressure relief and comfort, so it is safe to say that we'll be using this mattress to get a good night's sleep. The natural properties of latex will also help you get rid of the back pain, regardless of the position you're sleeping in, as well as help prevent allergies from happening, allowing you to get a whole night of restful sleep. In a nutshell, this mattress is ideal for sleepers who:

Features you should know about Dunlopillo Royal Sovereign mattress

Latex mattresses have always been in the league of their own, and this one is not an exception to the rule. To better understand what this mattress brings to the table, let's go over some of the key features and characteristics of this one.

7 comfort zones for improved support

Latex mattresses are generally known for being supportive but sometimes too firm. However, to prevent that from happening, this mattress is designed with 7 comfort zones with progressive comfort- softer comfort zones cushion your shoulders, hips and heels, while the firmer zones offer adequate support, balance and alignment for your spine and whole body. Dunlopillo latex instantly responds and adapts to individual profiles and movements, which helps you get a good night's sleep every time you lie down.

This Dunlopillo mattress is certainly what you'd call a supportive mattress, offering a perfect balance of comfort and support in just the right areas.


Another impressive feature of this mattress is its ability to completely isolate motion, allowing you and your partner to sleep without disturbing each other during the night. Both you and your partner will be able to switch the position you sleep in during the night without disturbing one another.

However, just because it's motion-isolating doesn't mean that it doesn't have a little bit of a bounce. A timeless classic such as this one wouldn't be as good as it is if it didn't provide just a little bit of a bounce to help you out with the extracurricular bed activities.


The 100% pure Dunlopillo latex core will also provide you with an absolutely quiet sleeping experience. Many pocket spring or open coil mattresses can make noise while you toss and turn during the night, but not this mattress. Dunlopillo Royal Sovereign Mattress is completely noise-free, which, once again, can come in pretty handy when you and your partner decide to put off sleeping for a little bit.

210mm 100% latex core

This mattress comes with a 21cm deep 100% pure Dunlopillo latex core. This natural latex core is derived from the sap of rubber trees grown in managed sustainable plantations around the world, which makes this core not only supportive, comfortable, and pressure-relieving but also eco-friendly.

This 21cm deep natural latex core makes this a medium-firm mattress, providing a pleasant sleep environment for all kinds of sleepers and sleeping positions. It is both firm enough to adequately support stomach sleepers, as well as soft enough to cushion your shoulders and hips if you sleep on your side or back.

Breathable & hypoallergenic

Latex's open cell structure is made up of millions of interconnecting microscopic air bubbles, ensuring unparalleled temperature regulation and breathability. Millions of air bubbles will quickly absorb all the excess heat and have you sleeping cool in no time.

Furthermore, latex is naturally anti-allergenic, anti-microbial and anti-bacterial, and paired with Actipro technology – this mattress is made completely hypoallergenic and safe to use.

Knitted Actipro refreshing technology

Despite having a zipper, this mattress does not come with a removable, machine-washable cover. However, to make sure the 65% Polyester, 35% Viscose cover stays clean and allergen-free for a long time – we have Actipro technology.

While we don't know a lot about the actual science behind this technology, we do know that it helps remove all the bacteria and allergens from the fabric while also making it allergen-resistant.


Dunlopillo latex mattresses are designed to last long by utilising their natural resilience to hold their shape. That is precisely why this mattress is virtually maintenance-free.

This mattress doesn't require turning or flipping at all, which is quite good when you consider how heavy it is and that it doesn't come with any side handles that could assist you with flipping.

On the other hand, you should rotate it head to toe every three months, just to make sure you don't end up with any imprints from continuously lying in the exact same position.

Furthermore, Dunlopillo Royal Sovereign Mattress needs to be regularly and properly ventilated, so make sure you always use it on a slatted bed base.

Review of Dunlopillo Royal Sovereign mattress


Now for the main event – the review of Dunlopillo Royal Sovereign Mattress. This one is called a timeless classic – and we have to agree!

Dunlopillo's Royal Sovereign Mattress is a medium-firm, 21cm deep latex mattress that will not be easy on your wallet, but will most certainly transform your sleep.

Made in the UK, this one was designed to make life better. This natural latex mattress will not only offer you unparalleled support and comfort but also incredible pressure relief, motion isolation, anti-bacterial properties and much, much more. As far as firmness is concerned, we'd give it a 7 out of 10.

The best thing about this Dunlopillo mattress, however, is its durability and longevity, which is something you'd expect from such a premium product. It won't sink or sag, and even if it does by some chance – you're protected with an 8-year guarantee.

You can get this mattress in four sizes – a Single (90cm x 190cm), Small Double (120cm x 190cm), Double (135cm x 190cm), and King (150cm x 200cm).

The open cell structure does not only provide pressure relief and comfort but also a great level of breathability and temperature regulation.

On the other hand, just because this mattress doesn't require turning doesn't mean that taking care of it is easy. The mattress is quite heavy, with King size weighing in over 54kg, so even rotating it or simply lifting it to tuck in the sheets might be a bit of a problem. Also, not being able to use this one on a solid base means you will have to get a new bed frame with a slatted base if you don't own one.

If the Royal Sovereign isn't for you, how about another all-latex mattress from Dunlopillo?

Dunlopillo Orchid Mattress

Dunlopillo Orchid Mattress is a beyond luxurious and comfortable mattress that provides fantastic support, motion isolation and pressure relief. In fact, even though it is all latex, it's so cosy you'd think it's foam.

But, it's not mushy or soft. In fact, it is perfect for those suffering from sleep-related pain, as it offers orthopaedic-like support and ideal contouring.

The mattress is also breathable, anti-bacterial and anti-microbial, making it the perfect choice for a healthy night's sleep even if you struggle with allergies.

It is also one of the most durable mattresses on the market so you shouldn't worry about your sizeable investment failing prematurely.

What makes this product better than some other similar ones?

What makes this mattress exceptional and better than some of the other similar ones is the generous layer of latex. Most latex mattresses come only with a thin layer of latex mixed in with other materials. In this case, on the other hand, we're looking at a 21cm deep latex base, which is a lot more than you can find in some other similarly priced mattresses.

How did we test the product?

First up, we started by ordering this product online. Fortunately, this was easy. All we had to do is visit the shop, enter our details and that was it.

Surprisingly, the delivery costs were non-existent, even though this was a heavy package. The delivery was free, albeit very slow. It took almost two weeks for the mattress to arrive, but once it did – we began our tests.

As expected, the mattress came in perfect condition. It was evident that the attention to detail was high, but once again – for a mattress this expensive, that's kind of what you have to expect.

To provide you with an objective review, each of our team members spent ten nights sleeping on this mattress, writing down all their impressions and notes about the mattress.

The first thing we noticed is how pleasant the mattress felt. It wasn't firm or uncomfortable, yet it managed to provide perfect support for all of us, regardless of our sleeping position. Also, it was both soft and comfortable and firm and supportive – a perfect balance.

It passed our roller and kettlebell test with flying colours, so you can expect it to last longer than 8 years, which is the period covered by the warranty.

All in all, we all agreed that this is a remarkable mattress, well deserving of its price tag and reputation.
