Shop Affordable Memory Foam Mattresses

A cheap memory foam mattress moulds to the contours of your body as you sleep, distributing weight evenly and relieving pressure at the shoulders, hips, and joints. Unlike spring-based builds, memory foam responds slowly to movement, creating a cradling effect that many sleepers find reduces aches from pressure points overnight. Browse the complete mattresses range to compare across all construction types, or explore gel foam mattresses if temperature regulation is a priority alongside the contouring feel. All memory foam mattresses at Factory Buys include free shipping across Australia.

How Memory Foam Mattresses Work

Memory foam is a viscoelastic material that softens in response to body heat and pressure, allowing it to conform closely to your shape before slowly returning to its original form once pressure is removed. This response is what separates memory foam from both spring and latex builds. Where a pocket spring mattress pushes back against the body with responsive bounce, memory foam absorbs and holds pressure, making it a particularly good fit for side sleepers and those with joint discomfort.

Many builds in this range include cool gel technology, either infused into the foam or layered across the surface, which draws heat away from the body overnight. If you run warm during sleep, prioritise listings that specifically mention gel infusion or a cooling comfort layer in the product description. For a natural alternative to foam construction, a latex foam mattress offers a similar contouring feel with a more responsive, breathable surface.

What to Consider Before Buying

Memory foam mattresses in this range are delivered compressed and rolled, which makes setup straightforward. Unbox the mattress in the room where you plan to use it, place it on your base, and allow it to fully expand before putting on bedding. Expansion time varies by model, so check the product page for guidance before your first night's sleep.

If you want to adjust the surface feel over time, a memory foam mattress topper can add an extra layer of cushioning above your mattress. Adding a mattress protector from the outset protects the foam cover from spills and everyday wear without affecting the surface feel.

Sizes Available

Cheap memory foam mattresses at Factory Buys are available across all standard Australian sizes. A single mattress suits a kids room or compact guest setup, while a queen mattress remains the most popular choice for Australian master bedrooms. For those who need the widest standard surface available, a king mattress is the natural step up. Always confirm the listed dimensions and thickness on the product page before ordering, and match the mattress depth against your base and fitted sheets.

How do I choose firmness in a memory foam mattress for my sleep?

Start with your sleep position and how you like the feel. Side sleepers often prefer a softer, more cushioning feel, while back and stomach sleepers usually suit a firmer option for steadier support. If you dislike a deep “sink-in” feel, choose a firmer foam. Use the product listing’s firmness notes to decide.

What size and thickness should I measure for my bed base?

Factory Buys mattresses are Australian sizes, so match the mattress size to your base or frame first, then check the exact dimensions on the product page to confirm fit. If your base has edges, measure the internal space as well. For thickness, consider overall bed height and ease of getting in and out, and check base suitability on the listing.

Which features matter most: cooling gel, breathable cover, or support core?

The support core matters most because it controls how well the mattress holds you overnight. A breathable cover can help with airflow and comfort, and cooling gel can be useful if you sleep warm. Compare these features alongside firmness and thickness on the product specs so you’re not choosing on cooling alone.

How long does a mattress in a box take to expand?

Most mattress-in-a-box styles need time to fully expand after unboxing. Move it into the room first, place it on the base, then carefully unwrap and let it settle as per the instructions on the product page. It may look ready earlier, but full expansion can take longer, so allow the recommended timeframe before judging feel.
