This award-winning and five-star-rated original mattress by Simba Sleep is a unique hybrid mattress that combines polyfoam, memory foam, high-definition foam, and pocket springs.
The Simba Hybrid is an award-winning hybrid pocket sprung foam mattress by Simba Sleep. 🏆
It features four layers, including:
- A comfort layer of graphite-infused, open-cell Simbatex foam
- A core of up to 2000 Aerocoil mini pocket springs across 13 zones
- A CertiPur stability layer
- A base layer of no roll-off SupportCore with up to 1000 barrel springs
This is a medium-firm mattress that's an excellent choice for a wide range of sleepers, regardless of body size or preferred sleeping position.
The Simba mattress is supportive enough to prevent a build-up of tension, but also soft enough to allow your body to sink in where necessary.
This allows for optimal spinal alignment. 🦴
The Simba Hybrid mattress comes with an antibacterial hypoallergenic cover designed to maximise airflow.
The cover is also removable and machine-washable - but we'd always recommend making use of a mattress protector to safeguard your mattress. 🧼

Emma's Luxe Cooling mattress is the latest - and most advanced - mattress by the award-winning Emma Sleep. 🏆
This medium-firm mattress features a total of six mattress layers, which include:
- A temperature-regulating top cover that's removable and washable
- A top layer of ThermoSync® foam, infused with graphite particles that capture excess heat to promote temperature regulation
- A layer of Halo memory foam for body-hugging comfort

It allows for some sinkage to promote optimal spinal alignment and gives you very targeted support but the mattress still provides enough push-back so you won't feel like you're sinking into the foams.
Conveniently, the mattress also has excellent edge support, which isn't always the case with bed-in-a-box mattresses.
It features enhanced temperature regulation technologies so you won't feel as hot and clammy on this mattress as you may feel on other Emma memory foam mattresses.
The Luxe Cooling mattress also comes with a removable cover that can be machine-washed at 60℃, which is great for people struggling with allergies or those with hygiene concerns. 💦
The Emma Luxe Cooling mattress is delivered rolled up in a compact box, making it relatively easy to manoeuvre, but be aware that this mattress is on the heavy side.
Delivery and returns are free, and the mattress also comes with a 200-night trial and a 10-year guarantee.
As an aside: The Luxe Cooling mattress we tested was damaged on delivery, but we had a positive experience with the Emma customer support team, who responded to our request within 48 hours.

What is a hybrid mattress?
What happens if you have one good thing and add it to another good thing?
You get something even better. 😉
And that pretty much sums up hybrid mattresses.
A hybrid is a mattress composed of two or more materials, creating an end product that's even better than its individual components.
You'll generally find a foam layer above a pocket sprung layer as the bare minimum.
The materials selected for hybrid mattresses are often complementary. 💘

This means that one material is introduced to make up for the downfalls of another material. 👍
By way of illustration:
- Two of the most common materials in hybrid mattresses are memory foam and pocket springs.
- Memory foam offers cushioning support, but it can be too uncomfortable to move on and sleep too hot.
- Pocket springs, in contrast, are very comfortable to move on (though they could be too bouncy) and sleep much cooler.
- If a hybrid mattress combines these two materials, you'll get the perfect result - a bed with all the benefits of memory foam and pocket springs but with none of the downfalls.
The perfect example of this is the Nectar Hybrid mattress, which blends memory foam and pocket springs.
Who are hybrid mattresses suitable for?
We love hybrid mattresses and can recommend them for:
- People of any body size or weight.
- People of any age.
- People with any sleep position preference.
This level of suitability may be a lot to expect from a mattress. 😳
But since hybrid mattresses combine multiple materials, they are generally more suitable to a greater variety of people than single-material mattresses.

Here is a quick overview of who hybrid mattresses may be suitable for.
People who like sleeping on top of their mattress
Hybrid mattresses offer a sleeping surface that's a little firmer. 🧱
They also give you the feeling of sleeping on top of your bed rather than in your bed, as is common with memory foam mattresses.
If you don't like sinking into your bed too much but don't want to go for a pure pocket sprung mattress, then a hybrid like the Simba mattress is the right choice for you.

Restless sleepers
Hybrids are great for restless sleepers. 💃
- Memory foam mattresses can be uncomfortable for restless sleepers as you tend to sink into the foams too much.
- Spring mattresses can sometimes be too bouncy for very restless sleepers.
A hybrid mattress offers the perfect solution as you'll get minimal sinkage with less bounce, allowing you to move freely and comfortably all night long.
Hot sleepers
Pure spring mattresses offer the most breathability and are the top choice for heavy sweaters or hot sleepers. 🥵
But hybrid mattresses like the DreamCloud Luxury are also a great choice because they contain springs!
£540 OFF DREAMCLOUD + FREE BEDDING SET£ 408.07

The spaces between the springs create natural ventilation channels. 💨
This keeps the air flowing more freely and allows for enhanced airflow.
This makes hybrids much cooler and more comfortable than pure memory foam mattresses.
People needing orthopaedic support
Memory foam mattresses can be fantastic for people needing orthopaedic support, but they can often be too soft. ☁️
A hybrid mattress that combines memory foam and pocket springs is the perfect solution.

Sleepers can get the necessary support and stability from the springs, but still enjoy the body-contouring orthopaedic qualities of memory foam. 🤗
The Emma Premium is an excellent option if you're looking for that typical memory foam feel.

Couples
Since hybrid mattresses are suitable for so many different types of people, they're also a great choice for couples. 👩❤️👨
Since men and women often have vastly different body sizes and sleeping preferences, finding the right mattress for couples can be a nightmare.

But hybrids are so well-made that you're likely to find one that works for both partners!
They're also one of our top mattress choices for sex!
Try the Simba Hybrid mattress as one of our top picks!
Criteria to consider when purchasing a hybrid mattress
There are several key criteria to consider before purchasing your new hybrid mattress.
Mattress quality
Hybrid mattresses are generally more expensive than single-material mattresses, but this doesn't mean you should look for the cheapest option. 🙅
As with all mattresses, you need to focus on getting the highest quality mattress you can afford.

The quality of your mattress, after all, affects the quality of your sleep - and the quality of your sleep affects the quality of your life! 🥳
How do you determine quality?
A good factor to consider is mattress density. 👍
The higher the density of the mattress, the higher the quality.
- For foam mattresses, consider the actual density of the foams (stick to a minimum of 40 - 50 kg/m3).
- For spring mattresses, consider the number of springs used (don't go for less than 350 springs for the smallest size).
- For hybrid mattresses, consider both the density of the foams and the number of springs used.
Higher-quality mattresses also last much longer.
You can expect a good mattress to keep you comfortable for at least 10 years.
This is why most quality mattresses also come with a 10-year guarantee!
Some, like the Nectar Hybrid, even come with a lifetime guarantee. 🤩
But, we'd still recommend changing your mattress every ten years.
Mattress firmness
Most hybrid mattresses offer a medium-firm feel, but there is still some variance here.
Some may be softer, and some may be firmer. 🌩🧸🧱
The right degree of firmness largely depends on personal preference, but your build, weight, and preferred sleeping position also influence what degree of firmness is best for you. ⚖️
Here is a general guideline:
- Lighter-weight people and side sleepers generally do better on softer mattresses.
- Average-weight people and combination sleepers generally do better on medium-firm mattresses.
- Heavier-weight people and pure back sleepers or front sleepers generally do better on firmer mattresses.
If you're a combination sleeper and of average weight, then a hybrid is the perfect choice for you. 🥰
The Simba Hybrid is a great medium-firm option.
But if you're looking for something softer or firmer, you'd need to double-check that the mattress you're considering meets your firmness preferences.
Mattress size
The most common UK mattress sizes include:
- Hybrid mattress single: 90 x 190 cm (3’ x 6’3”)
- Hybrid mattress small double: 120 x 190 cm (4' x 6'3")
- Hybrid mattress double: 135 x 190 cm (4’6” x 6’3”)
- Hybrid mattress king-size: 150 x 200 cm (5’ x 6’6”)
- Hybrid mattress super-king-size: 180 x 200 cm (6’ x 6’6”)
So how do you know which size is right for you?
Deciding on the right mattress size will depend on:
- Whether you sleep alone or with a partner.
- Your budget.
- The size of your bedroom.
Larger sizes are always preferable for the most comfortable sleep, but you can do just as well on a smaller mattress. 💤
Couples shouldn't go smaller than a double-size mattress, though we'd recommend a king mattress.
If you're looking for the most luxurious mattress size, you can choose an emperor bed. 👑
The only hybrid mattress in a box we've found in the emperor size is the Otty Hybrid.
Risk-free trial periods
While we like hybrid mattresses, they won't be suitable for everyone.
That's why we always recommend purchasing an online mattress that comes with free delivery, a risk-free trial period, and free returns. 🙌
Why does this matter?
Trial periods give you the opportunity to try the mattress in the comfort of your own home for a set period of time. ⏰
It can take up to three weeks to get used to a new mattress - especially if your new choice is vastly different to your old mattress!
If, after the trial period, you still don't think the mattress is right for you, you can send it back - free of charge - and receive a full refund. 💰
Different mattress brands offer different trial periods.
For example:
- The Simba Hybrid mattress comes with a 200-night trial period.
- The DreamCloud Luxury Hybrid mattress comes with a 365-day trial period.
While you don't necessarily need a whole year to decide if a mattress is right for you, we love that many brands offer great trials and put their customers first!
£540 OFF DREAMCLOUD + FREE BEDDING SET£ 408.07
Many great brands also offer an old mattress removal and recycle service, so they'll take away your old one when they deliver your new one.
What do hybrid mattresses cost?
Hybrid mattresses are generally more expensive than all-foam mattresses. 💷
But, you should be able to get a good hybrid mattress from £500 for the smallest size.
Some budget retailers, like Happy Beds and Silentnight, also offer great options at more affordable prices.

Hybrid mattress discount codes
Most bed-in-a-box mattress brands offer frequent discounts, and we'd highly recommend you buy your hybrid mattress with a discount code. 🥳
This can get you up to 50% off!
You'll find all the best coupons on our discounts page.
For your convenience, we'll also advertise special deals throughout this article. 👍
Different materials used in hybrid mattresses
Each hybrid mattress is unique, but certain materials are used more often than others.
Let's take a quick look at the most common mattress materials found in hybrids.
Memory foam
Memory foam is one of the best materials for body-contouring orthopaedic support and motion-free sleep.
Even the world-renowned Tempur mattresses rely on NASA-approved memory foam. 🚀
Memory foam is best characterised by its memory imprint.
When pressure is applied, the foam becomes softer and allows the body to form an imprint.
Look at the demonstration in the images below:
This responsiveness ensures that the foam moulds perfectly to the body's contours, allowing for maximum comfort. 🤗
Due to its high adaptability and pressure-relieving properties, memory foam is often used for orthopaedic purposes.
As a downside, memory foam tends to be quite soft and retains more heat than other materials.
This makes it unsuitable for very hot and restless sleepers. 🥵
All-foam beds are also generally softer than hybrid beds.
If you want the benefits of memory foam without the downsides, then a hybrid is a good choice.
The Nectar Hybrid is one of our favourite hybrid memory foam mattresses!
Latex
Latex foam is a natural material made from tropical rubber trees, though you'll now find both natural and synthetic latex options. 🌴
Natural latex is a great eco-friendly choice, but it's often much more expensive.
Latex is breathable and provides a cooling effect, making these mattresses ideal for hot sleepers. ❄️
Latex is also naturally anti-mite and antibacterial, making it a great choice for anyone suffering from allergies. 🤧
Comfort-wise, it's very similar to memory foam, with good relief of pressure points and good motion isolation.
On the downside, latex mattresses can be pretty heavy, cumbersome to care for, and quite expensive.
Some mattresses include a combination of latex, memory foam and pocket springs providing the benefits of latex but at a more budget-friendly price.
The Hypnia Supreme Hybrid mattress has a memory foam pillow top with a natural latex layer and supportive pocket springs.
70% OFF HYPNIA SUPREME HYBRID + 2 FREE PILLOWS W/ PILLOWS2
Pocket springs
Pocket springs are usually found at the core of hybrid mattresses, providing stability, firmness, and good pressure relief.
Spring mattresses are often recommended for back support. 🦴

They have excellent edge support, meaning you can use the entire width of the mattress.
They're also a great choice for hot sleepers.
This is because the spaces between the springs allow for natural ventilation channels, enhancing airflow and overall breathability. 💨
This keeps the mattress cooler and more comfortable.
Most hybrid mattresses will contain at least one layer of pocket springs.
The Simba Hybrid is one of our favourite hybrid mattresses with 2500 pocket springs!
Some hybrid mattresses also feature other spring systems, like continuous coil systems, but we always prefer sticking to pocket coils.
These are much better quality and much more comfortable to sleep on. 😴
High-resilience cold foam
Cold foam is a type of polyurethane foam (also known as poly-foam) commonly used as the support foam or base layer of high-quality mattresses.
This is because cold foam offers great stability, support, and enhanced durability.
It's rare to find pure cold foam mattresses, but most hybrid mattresses have a cold foam support base. 😊
Should you buy a hybrid mattress?
We love hybrid mattresses.
They're an excellent choice for a wide range of sleepers, guaranteeing a great night's sleep. 😴
We'd recommend hybrid mattresses to:
- People who like sleeping on top of their mattresses.
- Restless sleepers.
- People wanting a good combination of comfort and support.
- People who sweat easily or feel hot at night.
- Couples.
We'd suggest you opt for a high-quality hybrid mattress with a good risk-free trial period so you can test it out and send it back for a full refund if you're not 100% satisfied. 🤞
