The Hypnia Supreme Memory Mattress is an all-foam mattress and the only Hypnia memory foam mattress. It's harder to directly compare this one to the other Hypnia mattresses as they are hybrid mattresses. However, we have done a broader comparison within our product overview.

Let's find out which sleeping positions will approve of this mattress, whether it's worth ditching your old mattress for and where it is ranked in their mattress range. We've taken the time to give you our full overview of the Hypnia Supreme Memory Mattress.

Great for side sleepers
You'll sink in enough to keep your body aligned while being supported.

This is totally normal, especially with a memory foam mattress, but it'll soon go.

Too soft for stomach sleepers
If you prefer a slightly softer mattress then you won't have a problem but the comfortable layers can make you sink in a little too much.

Overall support is good but not so much on the edge, we would suggest looking at the Hypnia Supreme Hybrid Mattress for better edge support.

Who is the product for?

Pure memory foam mattresses are usually quite firm mattress choices, but the Hypnia Supreme Memory Mattress one seems to be a little softer. You'll get a comfortable sleep with this product, yet also have the zoned support from the base. The memory foam definitely contours to your body which is most suited for side sleepers to keep their spine aligned, but you may sink into the top layer a little too much if you’re a front or back sleeper. This can make your sleeping position a bit uncomfortable.

What do we use this product for?

Thanks to the graphite particles, your body can keep at an ideal temperature which hot sleepers will be pleased with. On top of that, you can experience breathability and have your body aligned throughout the night at a reasonable price. To summarise it's for:

Features you should know about the Hypnia Supreme Memory Mattress

Of course, we know and can see from the name of this product that it is a memory foam mattress but what features make it different? We've picked out a few of the layers that we feel everyone needs to know the details of. The features we have chosen are the ones that change your sleep experience and encourage a good night's sleep.

Cooling properties

It’s usually known that memory foam retains heat. However, Hypnia has been able to combat this with graphite particles infused into the foam. This is their way of drawing heat from your body to keep you cooler. It's also a next-generation open-cell foam that helps circulate air. On top of this, there’s an Air-wave knitted cover that is designed with breathability and moisture-wicking in mind. Both of these layers work together to keep your body temperature regulated all night long.

Premium memory foam layer

This foam layer can also be found in the Hypnia Essential Hybrid Mattress. It’s the reason for receiving pressure relief and experiencing a softer mattress. This brings added comfort to a supportive base. No matter what your sleeping position or body shape is, you won't feel as if you're putting strain on the pressure points. Their premium foam has zones to adapt to different parts of the body e.g. shoulders, hips.

The premium foam layer features further down the mattress compared to the Essential Hybrid so you sink in more before reaching the support zones.


Thanks to the base of this mattress, the 15-year guarantee is possible. It means the product can last for a long time and prevent sagging over the years. You will feel the support from this final layer and its zonal structure that has been designed to relieve pressure too. This is the layer that changes the overall feel of the mattress to stop it from being too soft for everyone to sleep on.

Overview of the Hypnia Supreme Memory Mattress

I was surprised when I first tried out this mattress as it initially seemed quite bouncy for a foam mattress… and there are definitely no pocket springs in this one. However, this did mean it was quick to return to its original shape – unlike their Essential Hybrid Mattress. Even though there is a bounce to it, it still has good motion isolation so you won’t be woken up by a fidgety partner.

It’s worth noting that the Supreme Memory Mattress has okay edge support but not the best, so we would suggest taking a look at their Supreme Hybrid Mattress if that’s a deciding factor for you.

What we like about the Hypnia Supreme Memory Mattress

Person sitting in the middle of the mattress.

Let's break it down to a few points that we absolutely love about this product. These are the things that make us want to buy it so we can sleep on it every night for many years to come. Here they are:

  • The comfort of this mattress is incredible, although it's said to be medium firm like their other two mattresses. If you're someone who prioritises a comfortable mattress then this will tick this box. The different types of memory foam work well together for this.
  • The majority of people are side sleepers, so it's good news for all of you. This mattress is suited to those who sleep on their side more than anyone else due to the support it gives your shoulders and hips. Your body can stay aligned in this sleeping position to reduce the chance of waking up with aches.

What we didn't like about the Hypnia Supreme Memory Mattress

Now, for the things that are not too good about the product that might make you reconsider buying the mattress. It all comes down to personal preference but here are a few things that could sway your decision if you have a certain sleep style.

Hypnia's customer service and company information

Delivery – Hypnia provides fast, friendly and free delivery. The delivery driver was very helpful; as soon as the mattress arrived, the driver offered to take it to the room where I wanted it so I didn’t have to do as much lifting. The whole experience was very efficient.

Payment – You can easily pay with the standard methods, including PayPal. If you're looking for a way to split the payment into instalments, then you can opt for the choice of DivideBuy or Klarna.

Online customer service – Most of the time their customer service is quick but you could be left waiting for a few minutes. If you do find yourself in this situation, don’t worry! They have a fun game for you to play on their online chat so while you’re waiting for a response, you’ll have something to keep you amused.

Check the alternatives to the Hypnia Supreme Memory Mattress

There's another mattress in the Hypnia Supreme range and it's a hybrid alternative to the memory foam one. So, if you're looking for an equal balance of comfort and support then you might want to take a look. The Memory Mattress can be a little soft for some sleepers so it can be worth looking at the hybrid choices instead. There is their Essential Hybrid Mattress for a cheaper option, but the Supreme Mattress is the one at the top of their range.

Also, consider our new mattress comparison tool that compares the essential information about the top mattresses in the UK market head to head for more potential alternatives.

Hypnia Supreme Hybrid Mattress

Close up of the Hypnia Supreme Hybrid Mattress.

We have picked this mattress as our alternative to the Hypnia Supreme Memory Mattress as they are of the same quality but with different designs. It gives you the option of two mattresses that have features on one and not the other, so you can find the right one for you. However, both of them are durable and practical for their purpose.

The noticeable difference between the mattresses is this mattress includes an integrated topper. This is the layer where the comfort comes from and it's made of memory foam like the whole of the Supreme Memory Mattress.

What makes this product better than some other similar ones?

The Hypnia Supreme Memory Mattress is a better choice than the other Hypnia mattresses due to the smaller details. To start with, this one has handles on it so it can be manoeuvred with ease – unlike their essential one that has none. In comparison to the Supreme Hybrid Mattress, this one has a removable cover which is super practical and low maintenance which is definitely something we look for.

For lightweight sleepers, this is a better pick because it favours comfort over support so it won't be a firm mattress to lie on. That's not to say there is no support in this one, as there certainly is, but comfort is the main achievement.

Is the Hypnia Supreme Memory Mattress eco-friendly or sustainable?

The mattress cover uses polyester which is a bonus for the durability and that's reflected in their warranty, but the impact on the environment is not so good. Of course, the rest of the mattress is made with memory foam and it's not the worst material to use for the layers but there are better materials out there.

All mattresses are manufactured with renewable energy and the company works with recycling operators to make sure every returned mattress goes to a good home. The mattress itself may not be most eco-friendly but you will find a section of refurbished mattresses that are returned mattresses that have been fully restored.

Buying a new mattress is a big commitment but with Hypnia’s 200-night trial period, you can easily return the mattress. There is also a 15-year warranty so you can feel at ease knowing the mattress is designed to last.

How did we test the product? 

We can give you our opinion on all the products we test out, however, it's always better to understand how we actually trial them to get to our final overview. On a broader level, here are a few tests that we follow with every product we assess.

To make things clearer, here's how we test the practicality of a mattress:

Overall impressions of the product after the testing

This Hypnia mattress overview applies to every size available, whether that's a double mattress or a single mattress – you will get the same experience. When we received the cooling mattress, it came vacuum-packed in a box. So, it just needs to be taken out, the package removed and left to expand.

Close up on the Hypnia Supreme Memory Mattress.

Once expanded, we could take a look at the smaller details. The mattress has a zip all the way around the edge so I found the cover easy enough to remove for washing. It’s more practical than the design on their Essential Mattress. The Essential Mattress also lacked handles and made moving the mattress difficult, but this one has two horizontal handles on the long sides. One downside to them is that they are underneath the mattress and that can make it tricky to hold onto – so you might want to take a look at the Hypnia Supreme Hybrid Mattress for better design features. Of course, this is only if it's important to your mattress choice but you won't need to regularly turn it – so once it's on the bed frame, you won't have to worry about moving it around again.

Being made from just memory foam does mean off-gassing is expected. So, bear this in mind when it comes to unboxing the mattress. You’ll just need to leave it to be aired out for a few hours and the smell will dissipate.

A definite upgrade from the Essential Hybrid Mattress but not quite on the same level as their Supreme Hybrid Mattress. You should consider this mattress if you’re a side sleeper or combination sleeper.

FAQs about your Hypnia Supreme Memory Mattress

Here's a quick summary of the questions you might be searching for the answers to.

Is the Hypnia Supreme Memory Mattress suitable for couples?

Yes, it is because there's little motion transfer so you can both sleep peacefully without waking the other up.

Is the Hypnia Supreme Memory Mattress good for hot sleepers?

This mattress uses next-generation breathable foam, infused graphite particles and has a breathable fabric cover. All of these help to keep the all-foam mattress cool through the night.
