How to Choose the Right Mattress Size and Protect It for Long-Lasting Comfort


Selecting the perfect mattress is a critical decision in enhancing your sleep quality and overall health. However, with so many options available, it can be overwhelming to decide. In this guide, we'll walk you through how to choose the right mattress size, factors to consider, and how to protect your investment for years to come.

Choosing the Right Mattress Size

Consider Your Space: Before anything else, measure your bedroom. Ensure there’s enough space to fit the mattress of your choice while allowing room for movement and additional furniture.

Think About Sleeper Size and Position: Who is the mattress for? A single adult might find comfort in a single or double mattress, while couples typically opt for a queen or king-size. Consider your height, sleeping position, and if you share the bed with a partner or pets.


Bed Sizes and Mattress Dimensions

Australia has seven commonly available mattress sizes. Single bed, Long Single, King Single, Double size, Queen size, King size and Super King size.

  • Single: Ideal for children and teens. 
  • Single XL: Ideal for one person when space is at a premium.  Also known as Long Single and Single Extra Long.
  • King Single: Ideal for growing children, teens and mature single sleepers.
  • Double: Cosy for two sleepers, roomy for one.
  • Queen: Ideal for couples and the bed size most commonly sold.King: Becoming more and more popular because of its generous sleep area.
  • Super King: Not very common as a mattress size, but more popular for bed linen. Created because people often buy a doona and doona cover one size bigger that their bed size.  (For example - Super King linen on a King size bed).

Future-Proof Your Choice

Are you planning to move, or is your family growing? A mattress is a long-term investment, so think ahead to avoid sizing issues in the future.

Factors to Consider When Choosing a Mattress

  • Firmness: Tailor this to your sleeping position and comfort preference. Side sleepers may prefer a softer mattress, while back or stomach sleepers might opt for a firmer surface.
  • Material: Memory foam, latex, innerspring, or hybrid—each offers different levels of support, cooling, and durability.
  • Budget: Don’t compromise on quality. A good mattress is an investment in your health.

Protecting Your Mattress


Use a Mattress Protector: A quality mattress protector shields your mattress from dust, allergens, and spills. Opt for a waterproof, breathable protector to keep your mattress in pristine condition.

Waterproof Fitted Sheets Against Spills: For extra protection, especially in children’s rooms or if you enjoy breakfast in bed, Fusion Tencel waterproof sheets are a lifesaver. They prevent spills from penetrating the mattress, which can lead to mold, mildew, and a host of allergens.

Consequences of Spills Penetrating the Mattress: Moisture can compromise the integrity of your mattress, encouraging the growth of mold and bacteria, leading to potential health issues and a shortened mattress lifespan.

Enhancing Comfort with a Mattress Topper: A mattress topper is not just for protecting your mattress; it’s also a fantastic way to add an extra layer of comfort. Whether you prefer memory foam for pressure relief or a gel mattress topper for hot days, it’s an excellent way to extend the life of your mattress and improve your sleep quality.

Choosing the right mattress and taking steps to protect it is crucial for enjoying a comfortable, hygienic sleep environment. By considering the size, material, and firmness that best suits your needs, and by utilizing protectors and toppers, you can ensure that your mattress remains a haven of rest for years to come.
