How do I choose firmness for my sleeping position and comfort?

Side sleepers usually prefer a bit more cushioning for shoulders and hips, while back and stomach sleepers often feel better on a firmer, more supportive surface. If you share the bed, aim for a balanced feel that suits both. Check the product listing for firmness guidance and support notes.

What size and access measurements should I check before delivery?

Measure your bedroom space for the full mattress footprint, then check access points like doorways, hallways, stairwells, and lift sizes. A king mattress is bulky, so tight turns matter. Compare your access measurements to the packaged dimensions on the product page, and clear the path before it arrives.

Which matters more: mattress thickness, support type, or cooling features?

Support type is the priority because it affects comfort and how well you’re held overnight. Thickness can add comfort, but it’s only useful if the support underneath is right. Cooling features are a bonus if you sleep warm. Use the listing to compare support layers, firmness, and any cooling details.

What’s involved in moving, unboxing, and setting it up at home?

Free shipping applies to all mattresses Australia-wide with no exceptions, so you can focus on getting the setup right once it arrives. For easier handling, clear a path to the bedroom before delivery, and if the mattress arrives rolled, place it on the bed base before carefully unboxing it. Then follow the product instructions for expansion time, allow some airflow while any new-mattress smell settles, and keep the packaging until you are fully satisfied.
