King Mattresses

A king mattress is one of the most luxurious items you add to your home. The ultimate statement of elegance and space, a king provides a perfect solution for those seeking extra room to stretch out and indulge.

Whether you're upgrading your bedroom or creating a lush, relaxing sleep haven, a king mattress can ensure comfort and restful sleep every night. At Ecosa, we offer an extensive range of king mattresses in a box, designed for easy delivery and effortless setup.

Since a king bed gives you the most space, why not take it further by getting a mattress that is adjustable? At Ecosa, we have a range of mattresses that let you adjust your firmness as you need.

Our Ecosa Mattress, Pure Mattress and TrueFirm Mattress all allow you to tweak to the support that you deserve. So whether you want a cushiony yet supportive bed or a firm mattress for optimum alignment, you can have it all at Ecosa.

If you sleep with a partner who moves a lot, then having enough space in bed can help you stay rested even though they toss and turn. Also, if your bedmate has a different sleeping schedule from yours, an Ecosa king mattress can ensure that their different sleep pattern does not disturb yours.

Sleeping with your little ones can be a joy when you have ample space. With a king bed mattress, you can fit two of your small kids with you and your partner. You can also get your fur babies to snuggle with you as you sleep since there will be plenty of space.

Like all mattresses, the exact size of a king bed mattress can vary between brands and models, but only slightly. Usually around 203cm long x 183cm wide in Australia, our Ecosa king size mattress measurements are:

• Ecosa: 203cm x 183cm x 25cm


• Pure: 203cm x 183cm x 29cm


• CoolComfort: 203cm x 183cm x 28cm


• TrueFirm: 203cm x 183cm x 28cm


• Essence: 203cm x 183cm x 22cm


• AeroLux: 203cm x 183cm x 40cm

If you’re looking for an even bigger mattress for two people — yes, even bigger! — you can explore a super king mattress for the ultimate in spacious sleep.

While the space you have will be a huge factor to consider when you’re ready to buy a king mattress, there are some other key factors to think about. Remember, it comes down to you and your sleep preferences.

Do you sleep on your side mostly? Or your back? Do you want it firm or prefer a more medium or plush comfort level? Think about the type of comfort you want, and any specific support needs you may have.

Due to their size, king bed mattresses are an investment, so price is going to be important as well. And, of course, you need a mattress that will last, so materials and durability matter.

Be sure to browse our entire Ecosa mattress collection before making the decision that will shape your sleep — after all, you spend roughly one third of your life in bed, so what you sleep on matters.

At Ecosa, we offer several types of king size mattresses, including memory foam, hybrid, and pocket spring options. Each mattress type is designed to deliver lasting comfort and support, ensuring you wake up feeling refreshed every morning.

If you’re looking for a cooling mattress, we have options that help regulate your body temperature throughout the night. And if a soft, cloud-like embrace is what you’re after, we also offer a plush pillow top mattress* for true king size luxury.

A king mattress is perfect for couples looking for extra space to sleep comfortably together or for individuals who prefer the luxury of having extra room to stretch out.

If you tend to move around a lot in your sleep, a king size could be for you. It’s also a great option if you tend to have your little ones or fur babies joining you to sleep.

If you’re looking for something bigger than a queen mattress, then a king size mattress is the one.

For an even bigger sleep surface for two people, our super king mattress offers the ultimate in spacious sleep. If you’re a solo snoozer looking for something slightly smaller than a king, but more space than a double bed, give our queen mattress a try.

The key difference between a king mattress and a queen mattress is size. At Ecosa, our king mattress measures 183cm in width and 203cm in length, providing 30cm more width than a queen mattress. If you want more space to spread out, the king is the perfect option.

A super king mattress is even larger. While our king mattress measures 183cm in width, a super king mattress is 204cm wide, offering even more space for those who want the utmost luxury in their sleeping experience.

While they both have ‘king’ in their name, a king single mattress and a king mattress sit far apart on the size scale.

A king single mattress is designed purely for solo sleepers, measuring only 107cm in width — just a little larger than a standard single. While a king bed mattress is much wider at 167cm, making it extra spacious, even with two people sleeping on it.
