What Most Furniture Sites Won't Admit
Most single mattresses sold online in Australia are imported — including ours. We hold stock in our Australian warehouses.
Second truth: cheap kids' single mattresses use 20-25kg/m³ foam that compresses permanently within 1-2 years of daily use. 30-35kg/m³ foam lasts 5+ years. Always check the foam density — most retailers hide it.
