The Best Cooling Mattress Toppers

Last Updated May 27, 2022

Do you wake up in the middle of the night drenched in sweat? Ok, maybe drenched is a bit dramatic but living in Australia, you’ve likely experienced plenty of sweaty summer nights that make it hard to sleep. Well, the good news is you don’t have to suffer! Not when there’s modern technology like a cooling mattress topper to help you sleep cooly and soundly through the night. And not only will a cooling mattress topper help keep the night sweats at bay, it’s also a much more cost-effective option to upgrade and make your current mattress more comfortable. We’ve researched to find the 5 best cooling mattress toppers in Australia to help give you the cool and restful night’s sleep you deserve, and quick guide to help you find the right cooling mattress topper for you.

Cooling Mattress Topper Buying Guide

Sadly mattress toppers don’t come with built-in fans to reduce your temperature (although that’d be some neat technology if it was possible!), still they do use cooling materials to help you regulate your temperature. Let’s look at the key things to look out for when shopping for a new cooling mattress topper.

Material

Most mattress toppers typically come in two materials, either cotton or polyester, with a down alternative or memory foam. You can still find some feather beds, but they are harder and harder to find and do not perform as well as the current options.

Those looking for memory foam should look for one with a cover or make sure to get one with a cover as memory foam isn’t washable. The down alternative mattress toppers are easier to wash and maintain but do not contour to your body like memory foam, which we will discuss below.

Comfort & Temperature

Memory foam is by far more comfortable than a down alternative, but memory foam heats up much faster. To compensate, there is now such a thing as gel-infused memory foam with open cells to reduce the amount of heat a memory foam gives off.

With a down alternative, you get extra padding, but it does not conform to your body like memory foam. It will definitely help to make a firm mattress more comfortable but does not help to alleviate back pain or help your spine to align properly. Ultimately, the spinal alignment will help you to get a better night’s sleep.

Thickness

Most mattress toppers come in thicknesses of 1 inch, 2 inches, 3 inches, and 4 inches. The right thickness depends on a few different factors. First, if you have an old box spring and mattress set, then a thicker mattress topper will dramatically increase the height of your bed. As such, finding sheets for a much thicker mattress may be difficult if you have a very thick mattress topper. Thickness also plays a role in how firm the mattress topper will be, so if you want a soft mattress topper, you should probably opt for a thin one.

The Best Cooling Mattress Toppers

1. Ecosa Mattress Topper (Queen $400)

Featuring two memory foam layers, one charcoal-infused and the other infused with G-7 gel particles, the Ecosa Topper provides “cloud-like” comfort and breathability. The Ecosa Topper will give you a “squishier” sleep or will restore support and comfort to your current mattress with the product description claiming it will make your mattress 20% softer. If you have an Ecosa mattress and find the medium setting of your Ecosa Mattress too firm, the topper will give you some added comfort. However, you don’t need an Ecosa mattress to get the most out of this topper. Additionally, if you sleep hot this topper will help cool you down with its G-7 Gel Memory Foam. Infused with gel particles, the unique 3D gel structure allows air to flow through pin core holes, so you’ll have no more sweaty nights. Sleepers who find normal memory foam too hot will no doubt enjoy this matress topper too with the G-7 gel layer that allows for cooling airflow.

Cooling Mattress Topper FAQs

How long will a mattress topper last?

Most mattress toppers will last between two and ten years. Always look at the warranty to know the relative life span. The key to helping your mattress topper last longer is a mattress cover protector. If your mattress topper comes with a cover, you’re all set! If not, you may consider purchasing one to extend the life of your topper.

Do I need different sheets for a mattress topper?

For the most part, no. Most sheet sets now are deep enough for thicker mattresses. However, you should always measure before buying. Make sure to check the sheets are deep enough to cover the mattress and the mattress topper by adding their heights together for a final number.

What are some other ways to stay cool during sleep?

Other ways to stay cool while sleeping are to use fewer blankets, use a duvet with a thinner pad, use a fan, or reduce the temperature of your room with aircon. The clothing you wear to bed also makes a difference, so try sleeping in the lightest amount of clothing possible (or naked, even!).
