Single

A single mattress fits the smallest of Australian bed sizes and is a great size mattress for solo sleepers, particularly children, teenagers, and young adults. Measuring 920mm by 1880mm, it offers enough space for a comfortable night's sleep without taking up too much room. This makes it ideal for smaller bedrooms and guest rooms. Single beds are also great for transitioning children from a toddler bed to their first 'big kid' bed, providing them with a cosy and secure sleeping environment.

In addition to being a practical choice for individual sleepers, single beds can also be a versatile option for multi-purpose rooms. They can easily double as a daybed or a place to lounge, read, or watch TV during the day. Whether you're furnishing a child's bedroom or outfitting a compact guest room, a single mattress from Beds n Dreams offers a good dose of comfort, functionality, and space efficiency.
