Australian Mattress Size Guide (2025)

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.

If comfort is high up on your priority list, but so is space saving, a long single mattress could be a great idea. It’s 920mm wide. So, the same width as a standard single mattress. However, it’s 2030mm long. That means it gives you an extra 150mm of leg room in comparison to a standard single mattress. A long single mattress can be perfect for growing children and teenagers. It can also be a great fit for a solo adult sleeper whose bedroom floor space doesn’t quite allow for the width of a king single or queen mattress.

The dimensions of the long single mattress make it a clever choice for a snug bedroom, a guest room, or even a studio apartment. And it can serve purposes beyond just being a sleeping option too. For example, it can work great as a daybed in a living area, providing a comfortable and cosy spot for relaxing with a book or a cup of tea.

A king single mattress size is an excellent option for those who need a bit more space than a standard single size bed but don't have room for a double bed frame. Measuring 1070mm by 2040mm, a king single mattress provides extra width and length, making it ideal for growing teenagers, taller individuals, or anyone who enjoys a bit more room to stretch out. The extra space promotes a good night's sleep without feeling cramped, which can be particularly appealing for those who move around a lot during the night.

King single beds are also a fantastic choice for guest rooms, offering a versatile sleeping solution that can accommodate a wider range of guests comfortably. They strike a perfect balance between space-saving design and comfort, making them suitable for smaller apartments, shared rooms, or any bedroom where you want to maximise floor space without compromising on sleep quality. With a king single bed from Beds n Dreams, you can provide your family or guests with a cosy, yet spacious sleeping experience in any setting.

A double bed, with mattress dimensions of 1380mm by 1880mm, is a popular choice for couples and solo sleepers alike. It provides enough room for two people to sleep comfortably, making it an ideal option for smaller master bedrooms or guest rooms. For single sleepers, a double bed offers plenty of room to stretch out and enjoy a luxurious sleep experience. The double mattress fits well in various bedroom sizes, providing a spacious sleeping surface without overwhelming the room.

Double beds are also a versatile choice for growing teenagers or young adults who need more room than a single bed or even a king single bed can offer. While not as large as a queen size bed, double beds strike a perfect balance between comfort and practicality, making them suitable for apartments, shared rooms, or any space where you want to maximise comfort without taking up too much floor space. With a double mattress from Beds n Dreams, you can ensure a good night's sleep with just the right amount of space.

A queen size bed is a fantastic choice for couples or individuals who enjoy extra sleeping space. The Australian queen size mattress, with mattress dimensions of 1530mm by 2040mm, offers ample room for two people to sleep comfortably without feeling cramped, making it a great option for master bedrooms. For solo sleepers, a queen size mattress provides a luxurious amount of space to spread out and relax. The queen size bed allows for both comfort and space efficiency, fitting well in most bedrooms while offering a spacious sleeping surface.

A queen size mattress sits perfectly in a queen bed frame, providing a stable and supportive foundation. Queen size beds are versatile, making them suitable for various layouts and décor goals. Whether you're upgrading from a double size bed or setting up a guest room, a queen mattress from Beds n Dreams ensures that you and your guests enjoy a restful night's sleep. With the generous size bed and a supportive bed frame, a queen size mattress can be an excellent investment in comfort and quality.

A king size bed is a luxurious and spacious choice, perfect for couples who want a large sleeping surface or for those who simply enjoy spreading out in a spacious bed. With king size bed dimensions of 1830mm by 2040mm, the king size mattress ensures everyone has plenty of room to stretch out and sleep comfortably. This size is ideal for larger master bedrooms where space isn't a constraint, providing a commanding presence that enhances the room's overall look and feel.

Upgrading from a queen bed to a king size bed offers a noticeable improvement in sleeping comfort. The king mattress size provides lots of space, reducing disturbances from a partner's movements and allowing both sleepers to enjoy a restful night. Whether you're accommodating a growing family that enjoys occasional co-sleeping or simply wanting to indulge in more personal space, a king size bed from Beds n Dreams is the perfect choice.
