How to choose the right mattress size for you

No matter where you are in your decision-making process, it’s essential that before investing in a new mattress, you consider a few factors. While double beds are often a default selection in many situations, they’re not always suitable. In smaller apartments and units, lofts and granny flats, a double mattress may not fit through the door of the space or simply take up too much room for the rest of the furniture to fit comfortably. Particularly if you’re renting your home, it’s important to allow for flexibility while moving. 

To reduce the bed's footprint, a king single mattress can often be the ‘just right’ of bed sizes. Long enough to accommodate tall teenagers and comfortable enough for an older relative in a semi-detached bedroom. Even in guest bedrooms, if you’re more likely to have single guests staying the night, a king single mattress is a space saver that doesn’t compromise on quality and comfort. All of our king single mattresses for sale are the Australian standard size of 107 x 203 cm, a perfect in-betweener for those more intimate bedroom spaces.

FAQs 

What size is a king single mattress?

A king single mattress typically measures 107 cm (42 inches) in width and 203 cm (80 inches) in length. This size provides extra length compared to a standard single mattress, making it a great option for taller individuals or those who prefer more sleeping space.

What age group is best suited for a king single mattress?

A king single mattress is best suited for teenagers and young adults. Its extra length compared to a standard single mattress makes it ideal for growing children and taller individuals. It offers more sleeping space, beneficial for those who move around during the night or simply prefer a bit more room. This size is also a good choice for guest rooms or small bedrooms where space is limited, but comfort is still a priority.

How thick are king single mattresses?

King single mattresses typically vary in thickness, ranging from about 20 cm to 30 cm or more. The thickness depends on the type of mattress and its construction. For instance, innerspring mattresses might be on the thinner side, while memory foam or hybrid mattresses tend to be thicker to accommodate additional comfort and support layers. The ideal thickness can vary based on personal preference and the level of support and comfort desired.

Can king single mattresses accommodate two people?

King single mattresses are generally not designed to accommodate two people comfortably. They are 107 cm wide, which is narrower than a standard double or queen mattress. While they can technically fit two people in a pinch, it would be quite cramped. King single mattresses are best suited for single sleepers, particularly teenagers and young adults, who need extra length and a bit more room to move around compared to a standard single mattress.
