Best Types of King Mattress in Australia

May 6, 2024   By Clarisa Mcdonald

For Australians looking for the king of comfort in the bedroom, king mattress sizes are probably already on your radar. For a good night’s sleep, you need a careful mix of pressure point support, the balance of soft and firm, even distribution of your body weight, minimal motion transfer and plenty of space. That’s where a king-size mattress comes in. 

Different Types of King Beds

Aside from the actual types of mattresses – i.e. memory foam mattresses, innerspring mattresses, latex mattresses, pocket spring mattresses and even hybrid mattresses (more on this later) – the king-size bed itself can come in various forms.

King single mattresses in Australia measure 107 x 203, giving you the length of a king bed, but with a width somewhere between a single and a double. It’s ideal for growing kids or guest rooms that are on the narrower side. King singles are not to be confused with long single bed sizes that have the same length but narrower width.

A standard king-sized mattress measures 183 x 203, offering plenty of space for couples, families and even pets to join. 

For another level up, a super king-size – also known as a California king bed (or a cal king) – offers a whopping 203 x 203, meaning it’s as wide as it is long. Perfect for those who love their own space as much as they love their partner!

Ecosa’s memory foam mattress is available in all three types of king bed – king single, standard king and super king.

How Much Space Do You Need for a King Bed?

When choosing a new mattress, it’s important to think carefully about what size you’ll need for the long term. Quality memory foam mattresses have a lifespan of 10-15 years, so think ahead to reduce the need to throw out an old mattress. Thousands of mattresses end up in landfill each year – don’t add to it!

Think about the next few years and who will be using the bed. Are you planning to have more kids? Maybe move into a bigger home? Choose a mattress with longevity, and then work to maximise your space. 

Interior designers work to a 60:30:10 ratio when it comes to design. 60% of your space for furniture, 30% for walking space and 10% for anything else you have in your room. It’s also recommended to position your bed with the headboard against the longest wall, to maximise breathing space around the edges. 

So, measure your longest wall first, and work out which bed size would best fit in line with the 60:30:10 ratio. Don’t forget to factor in the size of bedside tables, and any extra centimetres that your bed base or frame adds to your mattress dimensions.

Shop the Ecosa memory foam mattress in king single, king or super king – and why not complement your choice with our solid timber bed base and bedside tables?! You’ll also find our ultra-plush gel memory foam topper in all king sizes, too!

Do you need a king bed?

If space isn’t an issue, then the main factor to consider is preference. Do you sleep alone or with a partner? Do you have children or pets lounging on your bed? Do you need the extra space? It really depends on your personal choices. We’ve seen people sleeping alone on a king-size bed, and it’s not uncommon to see couples snuggling up in a double bed.

On the other hand, if costs are your concern, Ecosa’s King Size memory foam is one of the most affordable King-size memory foam mattresses for Australians. Plus you get a 15-year warranty and next-day free delivery along with your purchase. If a king-size isn’t for you. Ecosa’s lineup is available in all standard mattress sizes.


What are the dimensions for a king bed frame?

For a standard king – 183cm x 203cm and for a Super King / California King Bed 203x203cm. Ideally, look for bed frames that have the right amount of allowance so that your mattress always stays in place. Check out the Ecosa King Size Timber Bed Base.

I bought a king-size bed, now what?

The next step to enjoying your new king-size bed is to trick it out with the right bedding. After all, sleeping on a bare mattress has never been the most comfortable. Check out Ecosa’s bed sheet sets here.

Ecosa’s Bamboo king sheets are our top choice for the smoothest feel, while the Ecosa Flax Linen fitted sheets and pillowcases are our picks for staying cool in the summer and warm during winter.

Should I just stick with a queen-size mattress?

For a quick-size guide, queen-size beds are only 153cm in width, while a standard king is 183 cm, and a cal king is 203cm wide. In this case, the best mattress to choose if you’re after spaciousness is a cal king. But, for smaller sleepers, queen size or even a double size should be sufficient enough for two persons.
