King Bed Size

Need some room to move? The king size mattress size is the perfect choice for couples and for those who love to spread out! This mattress is generous in its proportions and will give you a lot more space to yourself than a Queen. Beware though - kids and pets might see all that extra space as an invitation to jump up on the bed with you!

What is the size of a king size bed?

Larger than a queen and smaller than a super king - the king mattress size is the perfect happy medium!

King size mattress dimensions offer around 30cm of extra width over a queen mattress and are roughly the same as two long single beds, which gives both people enough space to stretch out at night, without accidentally bumping elbows!

They’re fast becoming one of the most popular mattress sizes in Australia because king bed dimensions fit comfortably within many modern bedrooms.

They’re often easy to transport as bed bases can be purchased as two long singles, making them perfect for couples or families that move regularly. Keep in mind that it’s important to check king size bed measurements carefully before purchasing, as they won’t fit into every space!
