How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
Who is Dorma?
Dorma is a homeware retailer carried exclusively by Dunelm in the UK.
They are known for their luxurious bedding, from mattress toppers and duvets to pillowcases and high thread count sheets. 🛌
They also carry curtains, cushions and towels to finish your bedroom in style.
Is the Dorma mattress topper comfortable?
Comfort is the big selling point for sleep products, so we assessed whether the Dorma mattress topper is up to standard.
Pressure-relieving memory foam filling
The Dorma memory foam mattress topper is medium firm, balancing a soft, luxurious feel with pressure-relieving support.
Memory foam moulds to the contours of your body through weight and heat.
The viscoelastic cells inside memory foam adapt to your shape, alleviating pressure on your hips and shoulders.
Once you reduce stress on those pressure points, you reduce the chance of waking up with aches and pains and encourage better sleep patterns.
And don't worry, when you get out of bed, the memory foam slowly bounces back and returns to its original shape.
Keeps you warm at night
Memory foam is known for its heat retention properties.
The topper's dense structure and limited air circulation trap body heat and keep you toasty warm in winter.
If you're a hot sleeper, we recommend the Simba mattress topper for a cooler alternative.
Breathable Tencel cover
The Dorma mattress topper has a cover made from 36% Tencel, 36% polyamide and 28% polyester.
Tencel is derived from cellulose fibres through a non-toxic process, making it eco-friendly.
It is a highly breathable material that encourages better air circulation to keep you cool at night.
Tencel is also moisture-wicking, absorbing your sweat, transferring it through the fabric, and evaporating from the other side.
This keeps your skin and bedding dry even if you're having a hot flush at night.
However, the Tencel cover can only do so much, and it cannot completely counteract the heat retention tendencies of memory foam.
If you're a hot sleeper, we recommend opting for a cooling mattress topper instead.
Who is the Dorma mattress topper not suitable for?
Unfortunately, the Dorma Tencel Memory Foam Mattress Topper doesn’t work for everyone.
After all, everyone has different needs when it comes to their sleeping habits.
Front sleepers typically need a firm mattress or topper to prevent excessive sinking and maintain optimal spinal alignment throughout the night.
The medium firmness of the Dorma topper might cause front sleepers to sink in too much, leading to potential discomfort and strain on their neck and back.
We recommend the Emma Flip Mattress Topper for stomach sleepers.
As we mentioned earlier, memory foam retains heat, making it difficult for hot sleepers to keep their body temperature down. 🔥
While the Tencel cover provides some breathability, it is not enough to balance the heat retention of the memory foam filling.
For hot sleepers, we recommend a cooling mattress topper instead.

Is the Dorma mattress topper worth it?
When it comes to a Dunlem mattress topper, Dorma has it covered.
The Dorma Tencel Blend Memory Foam Mattress Topper is comfortable and good quality for most people.
The memory foam filling combined with the breathable Tencel cover provides a cosy sleeping environment for side sleepers in winter.
However, this isn't the topper for you if you are a hot sleeper or struggle to get a good night’s sleep with a bad back.
