Best Super King Mattresses UK (2021)

The 180 x 200 cm super king mattress is a luxurious choice.

It's great for couples, but you'll also be comfortable if your small child or dog hops into bed with you. Or cat, hamster, frog, bunny - all pets are welcome in the Sleep Hero world 🐶🐰🐸

If you're looking at the height of your next super-king-size mattress, consider the following:

• Foam mattresses should have a height of at least 15 cm (5'9").
• Spring mattresses should have a height of at least 20 cm (7'8").

Let's take a closer look at who would do well with a super king mattress.

A luxurious choice for couples

The 180 x 200 cm super king mattress is a luxurious choice for couples.

This mattress is definitely wide enough to allow both partners to sleep comfortably - and even toss and turn if need be.

Your restless partner definitely won't keep you up at night - provided you have a good mattress with low motion transfer.

Low motion transfer means that the mattress will effectively absorb movements at the point of impact and not allow motion to travel through the mattress.

This is a win if you're sharing your bed with someone!

The super king mattress is also big enough to allow children or pets to hop into bed with you.

You'll all still have enough room to move and be comfortable.

An option for bigger builds

If you're of larger build or body size, then the super king mattress is also a good option.

You'll have more than enough space to move, and you can still share your bed with a partner - and sleep comfortably!

Ultimately, a good night's sleep is what it's all about 😄

Great for singles who like their space

No rulebook says singles can't splurge and invest in this luxurious mattress.

It's not necessary, of course, and singles will have more than enough space on the 150 x 200 cm king mattress, but if you have space and the budget available, then splurge away.

There are hundreds of 180 x 200 cm super king mattresses available, all made from different materials, with different firmness levels, and available at different budgets.

Which super king size mattress, then, is the best one?

There's no definite answer to this - but there definitely is a mattress that's best for you.

We'd advise that you pay attention to the material used, degree of firmness, delivery conditions, and money-back guarantees.

Below you'll find an overview of the different types of mattress materials that can be used for 180 x 200 cm super king mattresses.

Super-king foam mattresses

There are a large variety of foam mattresses available, including pressure-relieving memory foam, cold foam, and geltex or gel foam.

Most high-quality foam mattresses are made of a combination of these and include numerous foam layers.

For example, a mattress may be constructed like this:

• A top comfort layer of gel foam, which is less heat-retaining than memory foam and provides a comfortable feel.
• A core of memory foam, which has body-contouring properties, relieves pressure points and provides a cushiony feel.
• A zoned base layer of cold foam, which is firmer, offers support and provides stability.

A mattress of this construction will have great ortho properties and may be recommended as an orthopaedic choice.

Combining different foam layers will allow a mattress to merge the best properties of all the foams used.

Many of the bed-in-a-box mattresses that we recommend are foam-based mattresses.

If you're not a hot or restless sleeper, we would recommend opting for a super king memory foam mattress.

Pros and cons of foam mattresses

Super-king latex mattresses

While technically a latex mattress is also a foam mattress, its properties are a little different.

In contrast to memory foam, for example, latex foam offers a much cooler sleep and is easier to move around on.

This makes it a great choice for couples and restless sleepers.

Natural latex mattresses are also a great environmentally-friendly choice.

Natural and organic mattresses may be more expensive, but they don't contain any harmful chemicals and are often sustainably sourced.

Also, a mattress with natural fillings is a hypoallergenic choice that's great for people prone to allergies.

Latex mattresses are generally quite a bit more expensive than other foam mattresses.

Pros and cons of latex mattresses

Innerspring mattresses

Innerspring mattresses, in general, are characterised by their firmness, stability, and great breathability.

Springs create natural ventilation channels, allowing for enhanced airflow.

This allows for an overall cooler sleep, which works well for heavy sweaters.

Spring mattresses are well-suited to people of larger size, back sleepers, and stomach sleepers.

However, there are many inferior coil mattresses available, which should be avoided.

The Silentnight Eco Comfort Miracoil Luxury Mattress, for example, is often recommended as a good open coil mattress that's worth checking out, but, in our experience, we'd stay away from open coil mattresses, no matter how good they claim to be.

Instead, we would recommend going for pocket sprung mattresses, where springs are individually wrapped.

This enhances point elasticity, minimises motion transfer, and allows for great comfort.

Pocket sprung mattresses are also much more durable.

You'll also commonly find springs in hybrid mattresses.

These combine high-quality foams and springs to offer the best of both - great comfort, stability, support, and breathability.

Pros and cons of spring mattresses

Investing in a new mattress isn't always an easy task.

You want to make sure that you're investing in a high-quality product.

Here are some key criteria to look out for before purchasing your new 180 x 200 cm super king mattress.

Quality & density of the materials

As you've discovered, there are many different mattress materials available.

Some are cheaper. Some are more expensive.

One way to determine whether or not the mattress you're considering is of high quality is to look at the density of the foams used - or, in the case of springs, the number of springs in the mattress.

The higher the density, the more durable the mattress is and the longer its lifespan.

You can use the below table as a rough guide:

Stability, support, and firmness

Your mattress doesn't need to be firm to offer the right amount of stability and support.

A soft mattress, like the Emma Original, for example, still offers amazing support.

It all depends on the combination of materials.

Regardless of which material you go for, your mattress must be able to offer sufficient stability and support to keep your body in a healthy alignment while you sleep.

This is particularly important for side sleepers: Your hips and shoulders need to sink in a little more deeply while the rest of your body remains well-supported.

This will allow for optimal spinal alignment and is crucial to prevent lower back pain and stiffness.

Mattress firmness, in contrast, is largely a matter of personal preference.

That said, factors like age, body weight, and preferred sleeping position do play a role.

In general, heavier-weight people and back sleepers will require a firmer mattress and side sleepers, and lighter-weight people will require a softer or medium-firm mattress.

Firmness can be difficult to ascertain, so we've created a Sleep Hero firmness scale to help you.

Risk-free trial periods

No matter what pesky sales assistants may tell you, there is no way to know whether a mattress is right for you simply by lying on it for a few minutes.

It can take the body up to 30 days to get used to a new mattress.

This means that you need to give yourself the chance to really experience the mattress and see if it's right for you.

Most bed-in-a-box mattresses purchased online offer a risk-free trial period, which gives you the chance to try out the mattress in the comfort of your own home.

And if you're not happy?

Simply return it for a full refund 🥳

Of course, it's entirely likely that you and your partner want different types of mattresses.

What if you want a soft mattress and your partner wants a firm mattress?

What if you easily feel cold at night, but your partner is a very heavy sweater?

This can definitely create tension.

Sleep, after all, is vitally important and should not be compromised on.

But there are solutions.

Customisable mattresses

Customisable mattresses are becoming more and more popular.

Here, you can set individual preferences for each half of the mattress.

So, for example, your side of the mattress may be soft, but your partner's side may be firm. Or your side of the mattress may be made of memory foam, but your partner's side will feature latex foam.

This way, you'll both get exactly what you want.

Combining two single mattresses

You can also purchase two 90 x 190 cm single mattresses and place these next to each other.

This is a good option if you and your partner differ greatly in size and body shape and require two completely different firmness levels.

You can also easily bridge the gap between the two mattresses by investing in a bed bridge or a mattress topper.

That said, purchasing two smaller mattresses will end up costing you approximately 30% more than simply purchasing a standard super king size mattress.

180 x 200 cm super king mattresses can be quite expensive.

They are very large, after all.

But, if you're investing in a mattress of this size, then it really is worth focusing on the actual investment part of it.

A high-quality mattress with high-density foams is likely to last you a very long time.

You're looking at up to 10 years or more for a good mattress.

In the long-term, it definitely is worth spending a little bit more time, effort, and money in making your choice.

But, this does not mean you need to invest in a superbly expensive brand like Tempur.

Many high-quality brands are available at good prices 💵

When choosing your 180 x 200 cm super king mattress, we recommend that you consider quality over price.

You’re planning on keeping your mattress for numerous years - up to a decade - and it is better to invest in a higher-quality model.
