A king size bed is one of the most comfortable and roomy options out there for Australian homes. Coming in at 183 cm wide and 203 cm long, its an absolute goldmine of space for couples who like to spread out a bit, or for anyone who loves not feeling cramped. And let’s be honest, its size also gives your bedroom a bit of a luxurious feel – a nicely sized bed just makes the whole room feel more refined.
Whether you’re looking to upgrade for comfort, style or a bit of both, a king bed is a long term investment that will pay for itself in quality sleep. At Dreamo Living we’ve got a huge range of options across our king bed frames collection, designed to fit in with any style of interior and Australian room layout.
What Size Is a King Mattress in Australia?
If you’re wondering what size a king mattress is in Australia, the answer is approximately 183 cm x 203 cm. That’s wider than a queen-sized mattress by a full 30 cm and a major reason why couples are switching to kings. Less partner disturbance is a major bonus, especially if one partner is a light or restless sleeper.
As a king mattress is designed to fit snugly on a standard king bed frame, you can be sure of stable support and a neat, well-fitted look. Plus a well-fitted mattress stops overhang, maintains the structural integrity and makes your bed last longer. Want to compare different options? You can do that within our mattress range.
