Memory Foam Mattresses

How Memory Foam Mattresses Work

Memory foam is a type of viscoelastic foam. It changes density when heat and weight are applied, and slowly returns to its original shape once that weight shifts. The technology has been around for decades, and memory foam remains one of the most popular mattress types in Australia.

The difference between memory foam mattresses comes down to the layers. Some use memory foam throughout, while others combine it with different foam densities underneath. That layering is what gives each memory foam mattress its own distinct feel, and why two mattresses in the same range can feel completely different on the showroom floor.

Who's It For?

Side sleepers are the biggest group. In our stores, memory foam is the most requested mattress type among side sleepers. If you've been on a spring mattress and the feel isn't quite right, a memory foam mattress is worth trying in person.

Couples go for memory foam too. It's one of our most popular picks in double, queen, and king sizes.

Back sleepers also find the feel comfortable. The foam construction is different to what you get with springs, and many back sleepers prefer it once they've compared both in-store.

Choosing Your Best Memory Foam Mattress

Firmness is personal. Our memory foam range includes medium firm (the most popular), plush for those who prefer something softer, and firmer alternatives. Your body weight, sleep position, and pressure preferences all play a role. Come into any of our 50+ stores and try a few side by side. Our cOMFy experts can walk you through the options.

We stock memory foam mattresses in all standard Australian sizes: single, long single, king single, double, queen, king, and super king. Make sure your bed frame or bed base matches the mattress size you choose.

Looking After Your Mattress

Grab a mattress protector with your new mattress. Foam picks up moisture, so a waterproof protector keeps things fresh. You'll need one for our 30-night comfort guarantee too (it needs to be purchased in the same transaction).

Rotate your memory foam mattress every three to four months so the foam wears evenly across the sleeping surface. Pair it with pillows suited to how you sleep, and complete the setup with quality bedding. If you want to adjust the comfort level, mattress toppers can change the feel without replacing the whole mattress.
