Shop Affordable Soft Mattresses

Shop cheap soft mattresses across memory foam, cooling gel memory foam and pocket spring constructions, with thickness options ranging from 15cm through to 30cm to suit different base heights and sleep preferences. Soft mattresses prioritise pressure relief at the shoulders and hips, making them a practical choice for side sleepers, lighter sleepers who prefer a cradling feel and anyone moving away from a firmer surface. All mattresses in this range come with free delivery Australia wide and follow Australian standard sizing, so compatibility with your existing base or frame is straightforward to confirm. The full mattresses range covers every feel level from soft through to extra firm for shoppers still comparing firmness, and those specifically after a plush surface will find closely related options in plush mattresses listed alongside this range.

Soft mattress construction types

The most practical distinction within soft mattresses is between memory foam, cooling gel memory foam and pocket spring construction. Memory foam contours closely to body shape and absorbs movement, which reduces disturbance between two sleepers on a shared mattress. Cooling gel memory foam adds a temperature-regulating layer to the foam structure, which addresses the heat retention that standard memory foam can produce during the night. This makes cooling gel a strong option for warm sleepers who still want the contouring feel of foam without sleeping hot. Pocket spring soft mattresses use individually wrapped coils that compress independently, providing a more responsive surface with better airflow than foam alone. Shoppers comparing foam and spring construction in more detail will find the full selection of memory foam mattresses and pocket spring mattresses each available as a dedicated collection for a more direct comparison.

Choosing the right size

Soft mattresses here are available across all standard Australian sizes including single, king single, double, queen and king. The size filter on this page lets you narrow the range to the exact size needed before comparing construction types within it. For shoppers primarily concerned with the queen or king format, the queen mattresses and king mattresses collections each cover soft and other feel options within a single size category, which can simplify the decision if size is confirmed but feel is still being weighed. Confirm the exact dimensions on the product page before ordering, and check your bed base or frame dimensions match the mattress size rather than relying on the size label alone.

Thickness and fitted sheet depth

Thickness across this range runs from 15cm to 30cm depending on the model, and this affects both the finished height of the bed and the fitted sheet depth you will need to source. Thicker mattresses sit higher and can feel more cushioned at the surface, while slimmer profiles are useful for lower-profile frames and bunk configurations. Adding a mattress topper on top of a soft mattress increases the overall height further, so accounting for the topper thickness when selecting fitted sheet depth avoids a poor fit at the corners. A mattress protector sits between the mattress and the fitted sheet, adding minimal height while guarding against spills and allergens that would otherwise affect the mattress surface over time.

Completing the bedroom setup

With the mattress confirmed, the support structure underneath and the linen above determine how well the overall setup performs. Soft mattresses work across slatted, platform and ensemble base types, so confirming the base style is compatible with the chosen mattress construction is worth doing before ordering. Bed frames in metal, timber and upholstered finishes are available across every standard Australian mattress size for shoppers who also need the frame. For the sleep surface above, pairing a soft mattress with pillows in a softer fill complements the overall feel of the bed, particularly for side sleepers who need more give at the head and neck to keep the spine aligned.

Memory foam, pocket spring, or hybrid: which soft mattress type suits you best?

Choose a memory foam mattress if you want more contouring and a cushioned, cradling feel. A pocket spring soft mattress suits sleepers who prefer a bit more bounce and airflow. Hybrid options combine both, blending foam comfort layers with spring support, which can feel softer on top while staying stable underneath.

Which size soft mattress matches Australian mattress sizing and your bed base?

Factory Buys stocks Australian sizing mattresses and bed frames, so start by matching the size first, then confirm the exact length and width on the product page. If your bed base has a tight internal fit, check the base’s inside measurements too, particularly for king single, queen, and king sizes.

What mattress thickness should you choose for the feel you want and your fitted sheet depth?

A thicker soft mattress can feel plusher and sit higher on your base, which some shoppers prefer for easier getting in and out. A slimmer profile can suit lower frames and may feel a touch firmer. Before you buy, check your fitted sheet depth so the corners wrap securely, especially if you use a topper.

What should you prioritise for comfort, such as cooling gel, topper style, and partner disturbance?

Prioritise features that match how you sleep. Cooling gel styles suit warm sleepers, while pillow top or premium top options add a softer first feel. If you share the bed, pocket spring designs can help reduce partner disturbance. Free shipping applies on mattresses, so you can focus on feel and fit rather than delivery cost.
