A rare gem

You never know how good a company is until something goes wrong. In my case the issue was with the manufacturer not My Next Mattress. Throughout the period of my complaint this company have been 100% supportive, communication rapid and have lived up to their promise. In this world of commerce I feel I have had personal service of the highest quality. Our initial contact was also excellent and our mattress was delivered quickly and efficiently. Wouldn't go anywhere else from now on.

Customer focused

Customer focused, competitive, helpful and very efficient. Only issue I had was MNM omitted to include the agreed return of my old bed on the delivery documents, probably an oversight but caused me some inconvenience hence 4 stars.

Made with a core of 100% Dunlopillo Latex, the Diamond bed boasts fantastic durability, supreme natural comfort and a great price.

MyNextMattress carries the Dunlopillo Diamond in stock.

The Diamond is the sister mattress to the firmer Dunlopillo Firmrest. The Dunlopillo Diamond shares the same specification as the Firmrest, but the Diamond's latex is poured into the mould at a lower density (ratio of latex to air), making it softer.

As with all Dunlopillo mattresses, the latex is made by to a unique specification, one which has been a secret since 1929 when the first Dunlopillo was produced. The current generation of Dunlopillo mattresses boast the purest form of latex since the ...

The Diamond is the sister mattress to the firmer Dunlopillo Firmrest. The Dunlopillo Diamond shares the same specification as the Firmrest, but the Diamond's latex is poured into the mould at a lower density (ratio of latex to air), making it softer.

As with all Dunlopillo mattresses, the latex is made by to a unique specification, one which has been a secret since 1929 when the first Dunlopillo was produced. The current generation of Dunlopillo mattresses boast the purest form of latex since the Dunlopillo brand was formed many, many years ago.

This Dunlopillo mattress is a beautifully sumptuous and luxurious one. The natural latex unit this mattress is built around offers fantastic pressure relieving support. The latex moulds to the contour of the body perfectly and effortlessly. latex is a Natural material and does not require heat to soften, as some other man made materials do, making the Diamond a cool mattress at all times.

The Dunlopillo Diamond mattress is a no-turn mattress, making it easy to care for, although we recommend it is rotated once per season. The Dunlopillo Diamond has a smooth, quilted surface, offering even more comfort.

The Dunlopillo Diamond is 18cm deep and is covered in a stunning softknit material, which aids moisture and heat management, preventing heat levels from building up through the night.

Cannot fault it!
We had one given to us many years ago, but this brand new one is even better.
Great service too.
Great quality!

After being let down by [name removed] repeatedly, we cancelled our order with them and went here, so glad we did!
Great service and a superb mattress! We have one previously, but this is as good, if not better! Fully recommend to all!
Soft yet supportive
S Johnson
Verified Buyer
Hard to describe.
A soft feel, but still very supportive and almost like the feeling of floating. No more aches and pains. A great bed.

Mattresses need to breathe. With the amount of fillings and areas of space within a mattress, they can quickly hold heat and moisture. Over time this can influence the way a mattress behaves and also effect the life span of a mattress. 

Manufacturers have developed different ways of tackling the problem of Breathability in mattresses. Some brands have used vents to allow air to pass through the mattress. Some brands use state-of-the-art materials to cover the mattress, such as Coolmax or Outlast. Memory Foam has a reputation of storing heat and moisture, as foam requires heat to soften up.Memory Foam brands have overcome this problem by applying Coolmax and Outlast, they also use Open Cell technology. This technique is to simply allow the foam to settle with larger spaces between the foam cells. This allows heat and moisture to move freely without getting trapped.

Some mattresses are created in such a way that they do not require any additional Breathability methods. These mattresses are generally the entry level mattresses with Open Coil spring units and not a great deal of fillings.

MyNextMattress is developing a new and unique solution to the Firmness scale accuracy. Not seen anywhere else in the World, we will be measuring the Firmness of all our mattresses precisely and in detail.

We are the only company in the Country that will actually measure the Firmness of a mattress and give a grading out of 10. We are always aware that choosing your next mattress can be a difficult and time consuming process, therefore we strive to give as much information as possible on every mattress we sell.

The way our system works is by applying weight to a mattress. We will apply weight gradually and measure the amount the mattress dips. The more weight, the more the mattress will 'sink'. We would then measure the distance the mattress dips and plot these measurements (weight and distance) on a graph. This graph can then be used to tell us the Firmness category the mattress fits into, 7 out of 10 for instance.

Our Firmness Device provides a central rod which we apply weights to, on the bottom end there is a disc which pushes into the mattress. The top of this rod supports the weights and will sink according to the 'give' in a mattress. We measure from this point.

As a result of this unique technique, it will be possible for you to shop by the firmness of a mattress, this is not possible anywhere else.

Put simply, Hypoallergenic materials do not cause the amount of irritation that non-hypoallergenic materials can. Hypoallergenic materials can still cause irritation in some cases, the chances of this are reduced greatly. People with severe allergies and asthma may still have problems with items called hypoallergenic, but the risk is greatly reduced.

Hypoallergenic materials do not omit the same particles and fibres as other non-hypoallergenic materials. These particles are to blame for causing irritation and discomfort and in some cases the irritation can be dangerous. The Hypoallergenic properties of these materials can be created by number of techniques. Some materials (Memory Foam or Latex) are naturally hypoallergenic, others have been chemically treated.

Latex is the ultimate in luxurious natural materials (but can be synthetic in other markets). Latex is actually found in more than 10% of flowering plants around the world. About 20,000 species from more than 40 families. The Latex used in the bedding industry is taken from sustainable sources. Latex is perfect for mattresses because it is soft, hypoallergenic, natural and moulds to the shape of the body. 

Latex used in bedding also tends to be treated in such a way that it can be used by people who have Latex allergies! The technique used is to super heat the Latex unit, freeze it, super heat it and freeze it again. Once this process is complete, the harmful chemicals released can be chemically washed off, leaving it suitable for everyone. Latex is the material Memory Foam has tried to copy. Memory foam  requires heat to mould to the shape of your body and can therefore become too warm for some. Latex does not require heat and is soft at any temperature. As a natural material which requires time and various processes to be extracted, Latex can be more expensive that its rival materials, but the comfort levels achieved are well worth it.

Orthopaedic mattresses are usually the firmest mattresses on the market. A common mistake made by those with back pain, is to assume that a firm Orthopaedic mattress will be the solution. Personal comfort and a correct diagnosis of the cause of the pain should always be saught before purchasing an Orthopaedic mattress. 

Many brands have 'Ortho' mattresses. Terms used include 'Backcare' or 'Orthocare' and the theme is generally to produce a firmer feeling mattress. The idea is to create a mattress that the body can rest on without sinking in and bending the spine, causing pressure to build up. However, if a lighter person lays on a firmer mattress, they will find the spine will not align correctly as the loaded parts of the body (shoulders, hips etc) are not sitting correctly. For more information on the causes of back pain, click here or read about another solution in the Zoning description.

Pressure Points are created in the body when lying on a mattress which is not suitable for a persons physique. The Pressure Points are caused by putting stresses through the body. When the spine is not aligned correctly (i.e, straight), it can cause pressure to build up in the back, hips or shoulders (etc).

When a bed is too soft, the body sinks in, causing certain areas to be under the strain of the rest of the body. When a mattress is too hard/firm, then the weight applied can cause the body to flex/bend in the opposite way - causing a similar problem. Hips, shoulders and so on, are requried to be sunken into the mattress slightly more than the surrounding areas, as they carry the weight. When this is not the case, the lower back may be bent to compensate. The ideal mattress is one which will keep the spine straight.

Some mattresses require turning over, to aid even settlement. Others do not require turning, but will still require rotating.

The idea behind Zoning is to offer support where it is needed. The body has certain areas under pressure when lying flat. Zones are designed to split the mattress into sections and offer some areas more support than others. The end result will be a straight spine and pressure relieved. Some mattresses are split into 3 Zones, some into 5 Zones and some into 7 Zones and so on. The principle areas requiring support (and therefore their own individual Zones) are the head, shoulders, hips and feet. 

The spine should remain level as much as possible when lying on a mattress, therefore the areas with the most weight applied should be slightly firmer to allow for the extra loading. At the same time, the surrounding areas need to compensate for this and will not be as firm to allow the spine to remain straight.

The Zoning may be created by simply adding more layers of fibres where needed, or a different type of spring in certain areas. In latex or foam mattresses, it is possible to vary the density of the foam or latex to create different tensions where required. Latex mattresses can also be sculpted in certain areas to remove latex and therefore make certain areas softer.
