Why Choose a Super King Mattress?

A super king mattress is all about space, comfort, and luxurious rest. It’s wider than a standard king mattress, giving you the ultimate room to relax — perfect for co-sleeping with kids or just sprawling out solo. Our mattresses are built for durability and support, making them ideal for heavy sleepers or those who prefer memory foam or hybrid designs. Style-wise, they offer the perfect foundation for your bedroom, ensuring a restful night with minimal partner disturbance. Pair your mattress with a quality mattress protector and suitable bed base for optimal performance.

Features & Benefits of Super King Mattresses

Not sure what to look for? Start with mattress feel — choose from firm, medium, or plush options to find the right balance of comfort and support. A well-crafted mattress should provide excellent body contouring while maintaining proper alignment. Our super king size mattresses offer extra width for more comfort and space to stretch. Materials matter too: memory foam offers softness and pressure relief, pocket springs provide bounce and support. Explore our range to find the perfect super king mattress for your sleep style.

Mattress Sizes and Dimensions

A standard Australian super king size mattress measures 203cm wide by 203cm long, making it the biggest mattress size commonly available. This generous size is ideal for large master bedrooms and for those who value spaciousness. Compared to a standard king mattress (183cm wide), the super king offers an extra 20cm of width, making a noticeable difference in sleeping space. If you have a smaller bedroom, consider queen or king sizes, but if space allows, the super king mattress delivers the ultimate comfort and luxury.

Tips for Choosing the Right Super King Mattress

When selecting your new super king mattress, consider your sleeping position, firmness preference, and any specific support needs. Measure your bedroom to ensure enough clearance around the bed for easy movement and furniture placement. Pair your mattress with a supportive bed base designed for super king sizes to prevent sagging and prolong mattress life. Don't forget to add a mattress protector to guard against stains and wear.
