How do I choose the right firmness for my sleep style?
Start with your main sleep position. Side sleepers often prefer a softer feel for shoulder and hip comfort, while back and stomach sleepers usually suit a firmer feel for better support. If you share the bed, aim for a balanced comfort level. Use the product listing’s firmness notes to compare.
What mattress size should I buy to fit my bed base?
Match the mattress size to your bed base size first, then double-check the listed dimensions to avoid a tight fit. If your base has edges or a frame, measure the internal space too. Factory Buys uses standard Australian sizing, so a queen mattress is designed to fit a queen base.
Which matters most: thickness, support type, or cooling features?
Support type matters most because it affects how well the mattress holds you overnight. Thickness can change the feel and overall bed height, but it’s only helpful if the support layers suit you. Cooling features are a great add-on if you sleep warm. Compare all three on the product specs before choosing.
How long should a mattress in a box take to expand?
Most mattress-in-a-box styles need time to fully expand after unboxing. Place it on the bed base first, 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.
