The Queen sized bedframe is the most popular choice of bed size in Australia, measuring approximately 222 cm L x 161 cm H and comfortably fitting a Queen Mattress with dimensions of 153 cm. x 203 cm. And for good reason! This size is perfect for those couples who seek an extra bit of space or for those who just love a big bed for themselves! It can also provide some extra room for a young child (or a cute pet). If you’re looking to upgrade from your double bed or just want some extra space and comfort, a Queen-sized bed frame and mattress is an ideal choice.
