Why include a mattress protector?
For kids' single mattresses, a waterproof protector is essential. It blocks bedwetting accidents, spills, sweat and skin cells from reaching the foam. Without a protector, kids' mattresses develop stains and odours within 12 months. Most mattress warranties require a protector for warranty claims.
What Most Furniture Sites Won't Admit
Almost every single foam mattress sold online in Australia is imported from China, Vietnam or Malaysia — including ours. We import in bulk, hold stock in our Australian warehouses, and ship from there.
Second truth: foam density determines how long a kids' mattress lasts. 20-25kg/m³ foam compresses permanently within 1-2 years of nightly use. 30-35kg/m³ foam holds shape for 5+ years. Check the foam density before buying — most listings hide it.
