Choosing the Right Foam Mattress for Your Bedroom

Foam mattresses have moved on from basic foam slabs. Today's foam mattresses use layered construction with different foam densities, and our range covers different firmness levels and mattress sizes so you can find what works for you.

The key difference between foam mattresses is in the layers. Some use high-density foam throughout for a firmer feel, while others combine softer comfort layers on top with firmer foam underneath. That layered construction is what gives different foam mattresses their distinct feel.

Firmness and Comfort Levels

Picking the right firmness matters more than most people realise. Side sleepers tend to prefer a medium or medium firm mattress. Back sleepers do well with medium firm for an even feel. Stomach sleepers? A firmer foam mattress is the usual go-to.

Not sure what feels right? That's what our in-store teams are for. You can test different firmness levels across our foam mattress options and get honest advice from our cOMFy experts.

Sizes We Stock

We stock foam mattresses in every standard Australian mattress size: single, long single, king single, double, queen, king, and super king. If you're setting up a new bedroom, make sure your bed frame or bed base matches the mattress size you choose.

Care Tips

Start with a mattress protector. It guards against moisture and spills, keeping the foam in good condition. You'll need one for our 30-night comfort guarantee too (purchased in the same transaction).

Rotate your foam mattress every few months to distribute wear evenly. Pair it with quality pillows that match how you sleep, and consider mattress toppers if you want to adjust the feel without replacing the whole mattress.

Looking for a specific foam type? Check out our memory foam mattresses, gel foam mattresses, or eco foam mattresses. Or browse the full mattress range to see everything we stock.

FAQs

What's the difference between foam and memory foam mattresses?

Standard foam mattresses use high-density polyurethane foam for a consistent feel across the surface. Memory foam mattresses use viscoelastic foam that responds to body heat and weight, creating a different feel. Latex foam offers a bouncier, more responsive feel again. Each type has its own characteristics, and the best way to compare is to try them in-store.

How do I choose the right foam mattress firmness?

It depends on how you sleep and your body weight. Side sleepers tend to choose medium to medium firm. Back sleepers prefer medium firm for an even feel. Stomach sleepers often pick a firmer option. Visit us in-store to test a few and get advice from our cOMFy experts.

How long does a foam mattress last?

With proper care, a foam mattress serves you well for years. Use a mattress protector, rotate it regularly, and pair it with a solid bed base or bed frame.
