Our overall score is based on our safety tests only. We test mattresses against the Australian/NZ standard for mattress firmness, as well as checking the measurements of the mattress. Certain discrepancies between stated and actual dimensions can cause a safety hazard, so these are recorded and scored.
Whether the cot mattresses pass the sleep surface test method for firmness, AS/NZS 9911.1:2013. Parents are advised by safety experts to always choose a 'firm' mattress to minimise the risk of sudden unexpected death in infancy (SUDI).
Our recommended models all pass the standard test for sleep surface firmness, AS/NZS 8811.1:2013 which involves placing a test apparatus and assessing softness at various points. In addition, CHOICE also checks to see if mattress dimensions are as accurate as claimed/advertised measurements.
Discontinued models can't be found in retailers or online or are no longer manufactured. If you're considering a second-hand mattress, it's best to use one in clean, good condition, that's been stored well.
The RRP at the time of testing. If the price is $0 this is because the mattress comes included with a cot and is not available for individual purchase. Check the good points for the model for more details.
