Shop king mattresses online - 183 x 203 cm, the same length as a queen with an extra 30 cm of width. That width is what couples feel: room for a spreader, space when kids and pets arrive at 6 am, and less partner disturbance, especially on pocket spring and memory foam designs built for motion isolation.

A king suits bedrooms from about 3.2 x 3.2 metres, keeping roughly 60 cm of walkway each side. Before ordering, check the mattress can reach the bedroom - stairwells, tight corners and lift dimensions catch king buyers out more often than the room does.

King mattresses are delivered Australia-wide, eligible products carry at least a 12-month warranty, and 14-day returns apply. Compare queen mattresses for smaller rooms, or pair with king bed frames.
