Why choose a super king mattress?
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.
|Size:||180 x 200 cm|
|For whom?||Singles, couples, couples with a child or pet|
|Materials used?||High-quality materials such as latex, memory foam, cold foam, and springs|
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.
Bring on the family cuddles and popcorn 🍿
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.
Criteria to consider before purchasing a 180 x 200 cm super king mattress
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:
|Density (in kg/m³)||The expected lifespan of the mattress|
|Up to 25||Up to 2 years|
|30||Up to 3 years|
|35||5 - 6 years|
|40||6 - 8 years|
|50 - 60||10 years or longer|
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.

Affordable super king mattresses
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.
