Find the Perfect Fit

Length, width, and height aren’t just numbers on a product tag, they can make a real difference to your sleep comfort. In Australia, mattress sizes are mostly standard across brands, but slight variations can affect how your bed feels. At Amart, our mattresses follow Australian standard dimensions, with minor differences depending on the model.

Choosing the Right Mattress

Choosing the right mattress isn’t just about picking a number off the sales tag. Room space, body size, sleep habits, and bed features all play a role in determining how comfortable your mattress feels every night. Before we look into all the different sizes of beds, let's look at how thickness, support, and your space can significantly impact sleep quality.
And don’t forget, your mattress and pillows work together. Our Amart Pillow Bar has advice on choosing pillows that complement your mattress choice.


Thickness matters

Your mattress thickness isn’t just a number; it changes how supported and comfy you feel. Extra comfort layers, toppers, or spring variations can make it thicker or thinner. If you’re unsure, our Mattress Firmness Guide can help you compare support options.


Body size counts

  • Height: Your mattress should be 10-15cm longer than the tallest sleeper.
  • Weight: Choose the thickness based on the heaviest person.

For kids:

Go bigger than they need now; more room to grow means less hassle (and less spending) later.



Room-to-bed ratio:

  • Designers recommend at least 60cm clearance around the bed.
  • Short on space? Consider storage-smart beds like the Sorvino, giving you more bed space without cramping your room.

Browse our full range of mattresses to find the perfect size and style for your bedroom, or visit the Amart Sleep Zone to physically experience comfort and build quality.

Frequently Asked Questions

What is the order of bed sizes from smallest to largest?

In Australia, the orders are Single, King Single, Double, Queen, King, and Super King. Each step up offers more width or length, giving you extra space to stretch out.


What is the most comfortable mattress size?

Comfort depends on who’s sleeping on it. For singles, a Double or King Single works well. For couples, a Queen is often ideal, while a King provides more room to move.


Is a queen-size bigger than a king-size?

No, a King is wider than a Queen, making it more spacious for couples. However, both sizes are the same length, so the difference is mainly in width.

How to determine the perfect mattress size?
