Size of a king mattress
Perfect for couples or families, a king mattress offers plenty of room for two adults to sleep comfortably without disturbing each other. Ideal for master bedrooms, it’s the go-to choice for those who prioritize comfort and luxury in their sleeping space
king - 203 x 183 cm
Need more room? If you’re looking to accommodate two people or just want more width, consider a King Single (107 cm x 203 cm). A king single offers additional width and length while still being space-efficient. For two adult sleepers, we recommend moving to a Double (138 x 188 cm) or larger.
Pro Tip: Not sure if a single mattress will fit your room? Use tape to mark out 92x188 cm on your floor and ensure there’s enough clearance around it. And remember to account for the bed frame dimensions which can add a few extra centimeters. You can also check out our comprehensive Bed Size & Dimensions Guide for a full rundown of all Australian mattress sizes and tips for choosing the right size.
