Dorma Tencel Blend Memory Foam Mattress Topper

2 April 2024 4 min read

Have you noticed that your mattress is not as comfortable as before? It lacks support, tension in the pressure points is present all night or have there been signs of wear and tear on the surface? These are all reasons why you need a mattress topper. A mattress topper can also serve to transform a completely new mattress that is too firm for you, for example. Here is our Dorma Tencel Blend Memory Foam mattress topper review.

The beauty of mattress toppers is that they can turn an average mattress into an amazing one! So, in this Dorma Tencel Blend Memory Foam mattress topper review, we're going to see whether this topper can do that for you.

Who is the Dorma Tencel Blend Memory Foam mattress topper for?

Dorma Tencel Blend Memory Foam mattress topper is first and foremost for side sleepers. We will easily prove that claim to you. Body molding memory foam is simply perfect for side sleepers. It will cradle around the body, relieving pressure and giving support at the same time.
Back sleepers will also benefit from it. Allergy sufferers are another type of sleepers for whom this topper is good. 

The combination of polyester, memory foam and cotton gives a 100% hypoallergenic product. We will mention couples as well. Memory foam is well-known for motion isolation, so even if your partner is a restless sleeper, you won't have problems with tossing and turning on the other side of the bed. You won’t even feel it.

Features you should know about the Dorma Tencel Blend Memory Foam mattress topper

The following four are features you should know about the Dorma Tencel Blend Memory Foam mattress topper in our opinion. A more detailed understanding of these features will help you decide whether this is the right product for you or not.

Premium supportive memory foam fill

When you see the price of this topper, which is above the average for memory foam toppers, you will expect premium materials. And you will get that, at least when we are talking about memory foam. We will talk more about other materials in the following paragraphs.

Dorma, a UK company with a hundred-year tradition, has implemented premium supportive memory foam fill in this product. And it is much more than just supportive. You can expect pressure relief and comfort throughout the night. Durability is also top notch. We concluded this both after testing and because of the 10-year warranty.

Tencel

Before we explain the characteristics of Tencel, you should first know that Tencel makes 36% of the cover. And not the whole cover, but actually the part that is facing you. That part is certainly more important than the reverse one facing mattress. Anyway, we want to be sure that you know that the cover is not 100% Tencel, but actually a blend of 36% polyamide, 36% Tencel, and 28% polyester.

Tencel or lyocell consists of cellulose fibres. It is obtained by dissolving pulp and then further processing. It is primarily used in the clothing industry and the sleep industry. Tencel has numerous benefits. First, it is eco-friendly because no toxic carbon disulfide process is applied during processing. It is also highly breathable, wicks moisture away and it is anti-bacterial. Because of all these characteristics, it is one of the best materials for making pillow and topper covers.

Thermoregulating

Temperature regulation is listed as one of the main product benefits. Honestly, we're not sure why. First, Dorma suggests that it is suitable for autumn / winter season. This implies that it is quite hot, which is completely expected because memory foam is not a cooling material. Memory foam retains heat, which is why hot sleepers often avoid memory foam products.

We did not notice that this particular memory foam was something different. There are no vents for improved breathability or mesh borders. Gel foam, which reduces heat retention and promotes a cooling night's sleep, is also not added. The cover does contain Tencel and cotton, which are two cooling and breathable materials, and that makes the situation somewhat better, but there is also a lot of polyester in the cover.

Certipur certificate

CentiPUR is a certification program. In charge of this certification program is a non-profit organisation. When foam carries the CertiPUR certificate, it implies that it is made without ozone depleters, PBDEs and TDCPP flame retardants, heavy metals, formaldehyde and many other harmful substances.
Also emissions of Volatile Organic Compound (VOC) are low. All this is of the utmost importance for both customers and the environment.

That's why when you decide to buy a memory foam product, it is important to check certifications since memory foam is not sustainable material. So that’s the way to reduce harmful effects. However, UK laws and regulations are strict, which is why we think too much attention is paid to the CertiPUR certificate. In general foam products must meet many criteria in order to be placed on the market, with or without certifications.

Review of the Dorma Tencel Blend Memory Foam mattress topper

An image of a man holding Dorma Tence mattress topper.

Dorma Tencel Blend Memory Foam mattress topper is 6.5cm (2.5inches) thick. It falls within the average thickness of a mattress topper, but closer to the lower limit. Premium memory foam makes up for the average thickness. Sleepers of average body weight will feel as if the topper is thicker than it is because it is so supportive, comfortable and pressure relieving.

The topper firmness rating depends on the firmness of mattress. It moulds very well to the body and that's why we recommend it for side sleepers.

The cover is a combination of natural and synthetic materials. That blend works fine, a balance between durability and softness has been achieved. Breathability of whole product is average, and heat retention can be a problem for hot sleepers. People with allergies can safely use the topper since there will be no dust mites and other allergens. It comes with a 10-year warranty, which is significantly above the average for toppers, and even for mattresses.

KEY FEATURES:

  • Type: Cotton/Microfibre/Smartfill
  • Size: 74 x 48 cm (standard)
  • Depth: 14.2 cm
  • Warranty: N/A

What we like about the Dorma Tencel Blend Memory Foam mattress topper

What we don’t like about the Dorma Tencel Blend Memory Foam mattress topper

The common problems with the Dorma Tencel Blend Memory Foam mattress topper & how to solve them

The first problem is maintenance. Luxurious tencel blend cover is not removable nor is the topper fully washable. You can only sponge clean it. This problem is easy to overcome. Use a protector and bedding, wash them regularly and the sleeping environment will be clean.

Another problem is heat retention and breathability, but after all more than 90% of memory foam sleep products have the same problem and there is not much you can do about it. Firmness is medium, closer to soft, so stomach sleepers may sink too much leaving the neck in wrong position.

What makes this product better than some other similar ones?

Pressure relief certainly makes the Dorma Tencel Blend Memory Foam mattress topper better than some other similar ones. When you lie down on this topper, you'll feel like you're lying down on a cloud. Tension after waking up is going to be a thing of past.

That's not all. It is very comfortable and at the same time supportive. That's why it can significantly improve the night's sleep, even if the mattress underneath is not in great condition. We must not forget the warranty. Although it is high-priced compared to some other good mattress toppers, the warranty makes this quality Dorma mattress topper superior to the competition.

How did we test the product?

When we ordered the Dorma Tencel Blend Memory Foam mattress topper, it was available in stock, so it was delivered quickly. You can choose between free standard delivery and express delivery, which will cost you £5.95. You can also opt for the Click & Collect option, which is also free, if there is a Dunelm Mill store near you.

We followed the instructions and left the foam to recover from packing for 3 days. We could not perform the maintenance test because the cover is not washable. Topper passed the durability test with high marks.

We usually test the topper for as long as the mattress, because it is necessary for the body to get used to it completely before a trustworthy judgment can be made. That's why we tested it for weeks, with a special focus on side and back sleeping. We also tested it in rooms with different temperatures.

Overall impressions of the product after the testing

After the testing procedure, we can confirm that most of the manufacturer's suggestions meet the actual facts. The topper is truly comfortable and supportive, thanks to the premium memory foam. The quality of workmanship justifies the price, because every part of the topper is made according to high standards including Tencel blend cover. In our opinion, the manufacturer is certainly not right about temperature regulation being one of the main pros of this topper. It is not able to reduce body temperature. Due to many advantages, but also several obvious disadvantages, such as heat retention, our rating of the product is between 7 and 8.

I loved this topper when I first got it in 2017 but over time it developed large dents where my body lay, is this normal ? I’ve turned it regularly but no way is it as comfortable now.


Connie Hack 05/02/2024

Hi Pauline,
That is a feature of the memory foam, contouring to your body to provide support just where you need it.
But yes, coming up to 7 years of usage, it will likely need a replacement as you won't get the same performance as brand new. But, on the bright side, your mattress has been protected throughout that time and you don't need a full mattress replacement!
