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.
Hypnia Supreme Hybrid mattress composition
The Hypnia Supreme Hybrid mattress is composed of multiple layers as well as an integrated built-in topper.
These layers include:
- Highly breathable cover
- Memory foam layer
- Latex layer
- Honeycomb foam
- Pocket springs
This combination of foam, latex and pocket springs provides optimal comfort and support for undisturbed sleep.
But what are the individual benefits of these layers? 👇
The Hypnia Supreme Hybrid contains a top layer of memory foam.
Memory foam (also known as viscoelastic foam) is incomparable to other materials.
Memory foam adapts to your body to relieve pressure from the joints and encourage the natural alignment of your spine.
The muscles relax and the spine stays neutral all night, which prevents you from waking up with back pain.
Most memory foam retains heat, creating a warmer sleep.
However, the Hypnia Supreme Hybrid combines cooler materials for better temperature regulation.
But more on that later. 👀
Below the memory foam is a latex layer, which helps to add additional comfort.
Like memory foam, latex moulds around the joints but has a firmer feel to prevent the body from sinking too much.
Latex is manufactured with breathable pinholes throughout the material to encourage air to flow out of the mattress. 🌬️
It is naturally hypoallergenic, making it an excellent choice for allergy sufferers.
Latex is also one of the most durable mattress materials, ensuring the Hypnia Supreme Hybrid lasts even longer. ⌛
The honeycomb layer promotes the natural alignment of the body to help you stay supported all night long.
Unlike memory foam, this layer is made of much firmer foam designed like a honeycomb to ensure maximum stability.
Pocket spring layer
The base of the mattress has an advanced pocket spring system.
Pocket springs support the body by moving independently from one another and providing support in each individual area.
This prevents movement across the mattress, which means you shouldn’t feel your partner moving around in the bed. 🤸♀️
Mattresses that absorb movement are called low motion transfer mattresses.
Pocket-sprung mattresses also encourage the body to stay lifted to keep the spine in neutral alignment.
The pocket spring layer comprises 7 support zones, providing extra stability across the body.
In short, firmer springs will be zoned in the areas you need the most support.
Hypnia Supreme Hybrid cover
The Hypnia Supreme Hybrid mattress cover is made from a highly breathable OEKO-TEX-certified fabric.
This means materials have undergone various safety tests to ensure they do not include harmful chemicals or fibres.
The Hypnia cover also promotes air circulation to prevent you from overheating at night.
The cover has handles, making the mattress easy to move around when necessary.
This is particularly useful as the Hypnia Supreme Hybrid mattress is quite heavy.
But unfortunately, the cover is not removable, which is partly due to the design of the mattress and its integrated topper.👎
We encourage those with allergies or who sweat during sleep to invest in a mattress with a removable cover.

How comfortable is the Hypnia Supreme Hybrid mattress?
When laying on the Hypnia Supreme Hybrid mattress, it had a soft and slightly enveloping feel. 🥰
It gently cocooned the body without sinking too much into the mattress.
The layer of latex supports the body's natural shape with additional pressure relief from the memory foam.
A good all-round mattress
The Hypnia Supreme mattress is suitable for anyone looking for a medium-feel mattress that prides itself on comfort.
With its pocket springs, memory foam and latex layers, the Hypnia Supreme Hybrid mattress is suitable for most sleepers.
Our testers appreciated the feeling of the Hypnia Supreme Hybrid from the very first sleep.
Here’s what our sleep expert had to say about this highly comfortable mattress:
"The Hypnia Supreme Hybrid is a well-made, meticulously crafted mattress. A great option for people looking for a mattress that cocoons around pressure points. It helps the body stay lifted in any position, encouraging optimal spinal alignment and pressure relief."
Those who suffer from aches and pains in the joints may find relief in the Hypnia Supreme Hybrid mattress.
A solid base for more firmness
But it’s not just soft cushiony layers that make up this hybrid mattress.
The supportive pocket springs prevent the mattress from sagging and ensure you don’t sink in the foams too much. 🤿
The 7 comfort zone layers absorb the weight of the body whilst keeping it lifted and aligned throughout the night, no matter how much you move around.
Is the Hypnia Supreme mattress good for my sleeping position?
However, we wouldn’t recommend this mattress to stomach sleepers.
Instead, it would be best if you opted for a mattress with firmer support, such as the DreamCloud Luxury Hybrid mattress.
This hybrid mattress combines memory foam and pocket springs but with a slightly firmer feel.

Does the Hypnia Supreme Hybrid mattress sleep hot?
We tested this mattress during the summertime. 🌞
The Hypnia Supreme Hybrid mattress has excellent breathability.
Memory foam generally stores heat, which can create a warmer sleeping environment.
However, memory foam combined with pocket springs generally has better temperature regulation.
Excess heat can dissipate through the gaps of the springs for better circulation. 🌬️
Latex also has excellent ventilation as it is structured with breathable pinholes that help to push out excess heat.
The hybrid mattress stayed at a comfortable temperature throughout the night.
Warm sleepers may experience a cooler sleep on this hybrid mattress. 🌡️
However, hot sleepers should avoid memory foam altogether.

How much does the Hypnia Supreme Hybrid mattress cost?
The Hypnia Supreme Hybrid mattress is competitively priced. 💰
Latex is typically very expensive, so we think this is reasonable.
The Hypnia Supreme Hybrid mattress also comes with a 15-year warranty.
This makes it much better value in the long-term than cheaper mattresses with shorter guarantees.
Additionally, you can spread the cost over 3 instalments.
But if you're looking for a slightly more budget-friendly option, consider the Hypnia Essential Hybrid mattress instead.
We tried and tested this mattress and experienced exceptional comfort at a wallet-friendly price.

Unpacking the Hypnia Supreme Hybrid mattress
When we first unboxed our Hypnia Supreme Hybrid mattress, we noticed it had a strange smell. ♨️
This is completely normal and is known as off-gassing.
Most bed-in-a-box mattresses experience some form of off-gassing, and the smell can vary in intensity.
This should disappear within a few days, or even less in a well-ventilated room.
Does Hypnia Supreme Hybrid come with a guarantee?
The Hypnia Supreme Hybrid mattress comes with a 15-year guarantee. 🤞
A guarantee ensures your mattress is protected from manufacturing faults so you can enjoy its comfort for years to come.
This also includes conformity defects due to manufacturing faults and sagging of more than 10% of its original thickness.
15 years is much longer than most mattress guarantees.
In fact, top brands such as Simba and Emma Original mattresses only come with a 10-year guarantee.
But some mattress brands include a lifetime guarantee.
Should you buy the Hypnia Supreme Hybrid mattress?
Overall, we had a positive experience with the Hypnia Supreme Hybrid mattress. 👍
The mattress is highly comfortable whilst providing excellent support for the entire body with its 7 comfort zones.
