Reasons to Buy

Many reviewers mentioned that the latex mattress was comfortable and provided excellent support in keeping with the springy latex in both the support and comfort layers.

Good quality mattress of adequate depth and good components that should last for many years to come.

A few customers reported that the mattress provided good temperature control and didn't feel as hot as memory foam which is in keeping with the better and more breathable materials.

Which best buy recommended mattress that should help showcase the products potential as a good all-rounder.

Great medium tension which will have mass-suitability and suit most people who sleep on their back or side.

Reasons to Avoid

While several customers noted that they preferred the latex mattress to memory foam, there were no direct comparisons to other types of mattresses, such as traditional spring mattresses. This product is slightly different as it is made entirely of latex in both the comfort and support layers, where competing models normally only have it in the comfort layer.

May not give enough support for dedicated back sleepers who typically prefer a slightly firmer base layer tension.

Key Performance Indicators KPI question mark

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.


  • Initial Odour
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

What Makes The Dunlopillo Royal Sovereign Mattress Great?

Awarded a Which? Best Buy in 2019!

A Which? Best Buy is quite prestigious as each mattress reviewed undergoes significant testing before being scored and tested against others in the industry. You can be assured of a great product when you choose a Best Buy.

Natural 100% pure Dunlopillo latex for superior comfort

Latex is a luxurious material of natural origins and is one of the better materials for mattress construction due to it's softness, breathability and resilience. You will find latex often used as a top comfort layer and occasionally used as a core/base layer due to it's additional supportive properties.

Seven comfort zones for extra support

A mattress with seven comfort zones is designed to provide a customized sleeping experience for the individual. It takes into account the body's natural curves and contours, as well as its unique pressure points, to create a personalized sleeping surface that meets individual needs. The mattress is divided into seven distinct comfort zones with varying levels of firmness and support. These zones help to alleviate pressure in areas like the hips and shoulders, while providing extra support to areas like the lower back. This helps to reduce tossing and turning throughout the night and provides a more comfortable and restful sleep. 

Progressive comfort for a restful night's sleep

Pressure-relieving technology so you can wake feeling revitalised

A mattress with pressure-relieving properties can help to reduce pain and improve comfort for people who suffer from conditions like arthritis, fibromyalgia, and other chronic pain conditions. When choosing a mattress, it is important to consider the firmness, support, and pressure-relieving properties that will best suit your needs.

Breathable to regulate your body temperature

The mattress comes with breathable side vents that allow the mattress to remain cool while you sleep. Another benefit to being breathable is that you naturally sweat during the night and the cool and breathable nature means that your mattress will remain hygienic for many years to come.

Medium support

A medium tension mattress like this is the goldilocks of mattress tensions. Not too soft, nor too firm, medium is typically suitable for the vast majority of people that are looking for a good nights sleep. If you are of average build without back or neck problems, this should be a suitable product. If you are of lower BMI and a side sleeper, consider a softer mattress, whereas if you are of a higher BMI and suffer neck and back pain, consider a firmer tension.

21cm total mattress depth

21cm of mattress depth is enough to house a typical good quality spring system with decent support and comfort layers while also being thin enough to accessorise with standard mattress sheets. No need for deeper sheets and further purchases as a result.

Hypoallergenic for a healthier sleep environment

Allergy sufferers often experience the problem of waking up in the middle of the night or having to get up in the morning with a stuffy nose and eyes. The reason why you wake up with a stuffy nose is because your mattress has accumulated dust mites, mould and mildew, all of which are allergens. The solution is a hypoallergenic mattress is made from materials that do not support mould or dust mites. They also have anti-microbial properties that effectively kill any bacteria that may come into contact with it.

Durable due to natural resilience to hold shape

Knitted, soft-touch cover with Actipro technology for a refreshing sleep environment

We really like soft knitted covers as the fabric is incredibly soft and stretchy while also being breathable, helping to keep you cool while ensuring the mattress can breath. The result is a hygienic nights sleep that has you sleeping deeper, improving the quality of your sleep and reducing tossing and turning.

Single-sided, easy-care

A single sided mattress is typical for the industry and relates to how  a mattress has the comfort layer on one side of the mattress. only This means that the mattress only needs to be rotated rather than flipped. The benefit of single sided mattresses is that they require less upkeep in that there's no flipping, but also, there's less components involved in the creation which saves costs.

8 Year Guarantee

An 8 year guarantee is fantastic news for the consumer. A normal industry standard is 1 year. 8x the standard guarantee means that the supplier and retailer both feel that this product is pretty special. Buy with confidence, the average mattress typically gets replaced after 7 years and here we have the supplier offering beyond that

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

Which? Best Buy

Which? promotes informed consumer choice. They examine products through testing to provide an unbias uniformed overview. Their scoring system makes it easier and faster to make an informed purchasing decision. As a Best Buy, Which? consider this product to offer the optimal balance of price, quality and performance.


Latex mattresses will never be latex all the way through, rather, it will be used as a top later. We often find that latex foam, combined with either springs or reflex foam will be combined in order to create the perfect mattress.

Knitted Cover

It is common in the industry to have a knitted cover, these covers can come in a variety of patterns but are typically hard wearing and do not present problems for consumers.

Pressure Relief

One of the big complaints when settling into a new mattress is that it does not feel as comfortable as they hoped, where this mattress shines is in the enhanced pressure relief that it offers. Each part of your body exerts different amounts of pressure against the mattress and through the use of springs and foams, these products are able to offer significant pressure relief as a result across the entire body.


This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems


A Medium firmness mattress is the most common build offered due to the range of suitability offered in such a mattress. This type of mattress will be better suited toward averagely weighted people, while lighter people should opt for a medium-light, and heavier people considering a medium-firm.

21cm deep

 This mattress has a depth of 21cm which is around the average depth for a product to be. The benefits of this depth of mattress is that there is still enough room inside for a fair amount of comfort layer fillings, while still being able to reuse existing standard-depth sheets.


Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.

Fire Resistant

Fire resistant does not mean the product will never catch fire, rather, it will not go up in flames quite so quickly. Resistant to fire in the same way that I am resistant to kisses, sooner or later you end up giving in.

Handcrafted in the UK

Handcrafted in the UK means that the product is built here, by people being paid a fair and honest wage using certified and safe products of good quality and construction. UK manufacturing is some of th best in the world and all of that is reflected in this product

Approved by the National Bed Federation

The NBF is one of the most prestigious awarding federations in the industry, helped slightly by the fact that it is one of the only, however, it is still a great source of comfort knowing that this product holds approval by the team

Customer Reviews For The Dunlopillo Royal Sovereign Mattress

Based on 19 reviews

I first had a new Dunlopillo mattress (bed) in 1984 and I slept comfortably everafter. I reluctantly had to get rid in 1912 as i was downsizing and moving many miles down south taking only the two single beds in my spare room , which had nothing wrong with them but not as comfortable as I thought. I decided to return to what I knew and I'm so glad I did, my new mattress is heavenly!


For someone with a weak back and a tendency for sore joints this provides a good balance between back support and comfort. It is soft to the touch but supports well when you lie down. It needs a slatted base for ventilation.


We were attracted to this mattress with it being latex, Its a which recommended mattress, So knew it would be a good buy.Very comfortable with great pressure relief for my hip pain (my wife recently had surgery)


I had one many years ago which I believe was layers of latex rubber. It was excellent. I have had this one for some weeks now and it is very satisfactory. However, I am unsure whether it is made the same way.


- Very comfortable;- High quality (seems like it will last for years and years);- Good temperature control (if you struggle with the heat from memory foam then you'll probably find latex much better).


This is our 2nd Latex Mattress, previous one was 18 years old still as comfortable as the day we bought it, now transferred to guest room.Hope this one performs as well.


Tried one without springs for a change, really comfortable so happy with choice.


Very comfortable and supportive. Not as hot as memory foam in my opinion.


Very cosy, will be good I am told when perspiring as it is natural latex


Superbly comfortable with excellent support. Top quality mattress.
