What size mattress is a king single?

Ok, so how much bigger is a king single to a single? The answer is - significantly! Whereas a single mattress is 920mm x 1880mm, a king single size is a whopping 1070mm x 2030mm, making it wider and longer. Often when customers hear these mattress dimensions, they then ask if a king single is the same as a queen. The answer is no - a queen-size mattress still reigns supreme at 1530mm x 2030mm.
