Billions of bacteria can breed in your mattress when you don’t use a mattress protector, especially if your room is dusty and you’re prone to sweating when you sleep. A combination of all that dirt can leave your mattress looking and smelling dirty, which would ultimately reduce your quality of sleep.

Therefore, using a mattress protector is a great way to preserve the “health” of your mattress and ensure you get a good night's sleep. 

Now, while using a mattress protector is a good idea, you must be careful with your choice because many protectors don’t live up to their reputations. One product that seems to stand out is the Great Barrier Mattress Protector. But is it anything more than hype and marketing gimmicks? Read this review to learn everything you need to know. 


The Great Barrier mattress protector is a product of the Australian furniture company - Koala. Their products are known for sleek design and durability, and this brand sells two types of mattress protectors. 

The first is the Great Barrier mattress protector, which can accommodate mattresses between 23 cm and 29 cm, and the Deep Fit Great Barrier mattress protector for mattresses over 30 cm. Regardless of your mattress type - single, king, queen, or double- Koala has a Great Barrier protector for them all. 

Here are some features you will enjoy when you buy Great Barrier mattress protectors.

How Does the Great Barrier Mattress Protector Feel?

The Great Barrier mattress protector is soft to the touch and gentle on the skin. You can sleep on it without using bed sheets and not know the difference. The Silicone print and polyurethane stop fluids from soaking into the mattress, ensuring optimum dryness. In addition, the mattress protector is sanitised with antimicrobial treatment to ensure germs and bacteria don’t survive. 

What Is the Great Mattress Protector Made From?

The Great Barrier mattress protector is 100% polyurethane wrapped in a Tencel lyocell fabric. To ensure sustainability, the Tencel fibre used in making this protector is from wood sources. 


This mattress protector comes in five sizes for different types of beds. The width and length for single beds are 92 cm and 188 cm, respectively, while that of king single beds are 107 cm and 203 cm. Double beds have a width of 138 cm and a length of 188 cm. The width of the king size is 183 cm, and the length is 203 cm, while the queen is 153 cm in width and 203 cm in length. 

Additionally, all Great Barrier mattress protectors come in heights between 23 cm and 29 cm. Therefore, if your mattress is higher than this, you should buy the Deep Fit Great Barrier mattress protector. Those come in 30 cm and above in height, but width and length are the same. You should note that the Deep Fit Great Barrier mattress protector is only available for double, queen, and king mattresses.  


Another great thing about the Great Barrier mattress protectors is their price. You pay for quality products and get maximum value from them.

Is the Great Barrier Mattress Protector Right for You?

If you are new to using mattress protectors or intend to change an old one and switch to a new brand, the Great Barrier mattress protector is the best choice on the market. Not only does using this product make your sleep better, but it also makes your life easier.

Moreover, It is wrapped in Tencel fibre which ensures that it stays cool at all times, meaning you don’t have to worry about your bed being uncomfortable. In addition, bed bugs, allergens, dust, bacteria, and other microbes do not have a chance to survive on your bed anymore when you use the Great Barrier mattress protector. This is because the protector contains antimicrobial features.

Besides, one great thing about this product is that you can get the perfect size for any mattress. Thus, you don’t have to worry about the fit of the protector on your bed. In addition, the Great Barrier mattress protector is easy to assemble; just place it on your mattress and zip it in place. Cleaning is easy, too; all you need to do is wash it in the washing machine and spread it to dry.

So, it is not a question of whether the Great Barrier mattress protector is right for you; the protector is the best for you if you want to improve your sleep. 


There are too many stress-causing factors, and your bed should not be one. Your bed should be a place where you feel safe and secure. There is no other way to do this except to use a high-quality mattress and a sanitised mattress protector.

Although some mattresses are built to last with some antimicrobial properties, they breed bacteria when they get stained or dirty from prolonged use. Of course, you can’t put your mattress in the machine to wash; that is why you need a mattress protector.

Finally, the Great Barrier mattress protector makes it easy to have a germ-free bed. It's affordable, easy to use, and offers a 120-night free trial period. If this mattress protector doesn’t convince you, you can return the mattress protector for free with no questions.
