Shop Affordable Foam Mattresses

Factory Buys stocks a range of cheap foam mattresses with free delivery on every mattress, covering single through to king sizes to suit Australian bedrooms of all sizes. The collection includes memory foam, cool gel, and green tea memory foam constructions across a range of thickness options from 15cm through to 30cm, with firmness choices available to suit different sleep preferences. Filters for size, thickness, firmness, and price make it straightforward to narrow down the right option before comparing listings. Browse the full mattresses range for all construction types, explore memory foam mattresses for a dedicated selection, or shop gel foam mattresses if a cooling construction is your priority.

Choosing a foam mattress: where to start

Foam mattresses in this range vary across three key attributes: construction type, thickness, and firmness. Narrowing down your preference across these three areas before browsing makes it easier to compare options side by side.

Construction type affects how the mattress feels and performs over time. Memory foam conforms closely to the body and is a popular choice for pressure relief. Cool gel constructions incorporate a gel layer designed to help regulate surface temperature during sleep. Green tea memory foam is another variant in this range, combining memory foam with an infused layer. Check each product listing for the specific construction details before deciding.

Firmness options across the range include comfort, medium firm, and firm variants. The right firmness depends on your preferred sleep position and body weight, so review the stated firmness level on each listing carefully. If you are unsure where to start, the thickness filters on the left of the page let you browse by profile height, which can be a useful proxy for comparing support levels across the range.

Thickness options and what they mean for your setup

Thickness is one of the more practical considerations when choosing a foam mattress, as it affects both comfort and compatibility with your existing bed base or frame. The range is filterable by thickness bands, making it straightforward to compare within a specific profile.

Thinner profiles in the 16 to 21cm range tend to suit platform bases, bunk beds, or setups where a lower overall bed height is preferred. Mid-range profiles in the 21 to 25cm band are the most common choice for standard bed frames and bases, offering a balance of support and comfort. Thicker options in the 25 to 34cm range suit those who prefer a higher profile or a more substantial feel underfoot. For the most substantial profiles in the range, browse mattresses over 34cm for the deepest comfort options available.

Always confirm the mattress dimensions on the product listing match your Australian standard bed size before purchasing.

Choosing the right size for your bedroom

The range covers Australian standard sizes including single, king single, double, queen, and king across multiple construction types. Queen mattresses are the most popular size for couples and master bedrooms, offering a comfortable width without taking over a mid-sized room. Size filters on the collection page let you narrow the range quickly to only the listings relevant to your bed.

When selecting a size, use the Australian size label as your starting point and verify the exact dimensions on the product listing before adding to cart. This is particularly important when pairing a new mattress with an existing bed frame or base to ensure a proper fit.

Completing your sleep setup

A foam mattress works best when paired with the right base and bedding. A compatible bed base provides even support across the foam surface and can affect how the mattress performs and wears over time. For shoppers who also need a frame, the bed frames collection covers all Australian standard sizes.

Protect your mattress from day one with a mattress protector, which helps maintain hygiene and can extend the life of the mattress. A mattress topper is worth considering if you want to fine-tune the feel of your mattress after purchase without replacing it entirely.

Which foam mattress construction suits your sleep style best: memory foam, cool gel, or green tea memory foam?

Each construction type feels and performs differently. Memory foam conforms closely to the body and suits those who prefer pressure relief and a closer feel. Cool gel constructions incorporate a gel layer designed to help regulate surface temperature during sleep, which can suit warmer sleepers. Green tea memory foam combines memory foam with an infused layer for a different feel again. Check each product listing for the specific construction details and comfort notes before deciding.

What size foam mattress do you need, and how do you confirm the right fit?

Start with your bed size and confirm the mattress dimensions match your existing bed frame or base. Factory Buys foam mattresses are available in Australian standard sizes, so a Queen mattress is sized to suit a standard Australian Queen bed frame. All mattresses include free delivery, so it is worth taking the time to confirm the right size before ordering. Always check the exact dimensions on the product listing, particularly if you are pairing a new mattress with an existing frame or base.

Which thickness and firmness level should you choose for your setup?

Thickness affects both comfort and compatibility with your bed base or frame. Thinner profiles suit platform bases, bunk beds, and setups where a lower overall height is preferred, while thicker options suit those who prefer a more substantial feel. Firmness depends on your preferred sleep position and body weight, so review the listed firmness level on each product before adding to cart. Filters on the collection page let you browse by both thickness and firmness to narrow the range.

Are foam mattresses compatible with all bed bases and frames?

A foam mattress works best when paired with the right base. A compatible bed base provides even support across the foam surface, which can affect how the mattress performs and wears over time. Check the product listing for any base compatibility notes, and confirm the dimensions of your existing frame match the mattress size before purchasing.
