The depth or thickness of a cot mattress is an essential consideration when choosing the right mattress for your baby's cot. In Australia, there isn't a specific standard thickness for cot mattresses, but there are general guidelines and safety standards that parents should follow:
General Thickness Range: Cot mattresses typically range from 8 to 12 centimetres in thickness. This range provides a balance between comfort and safety.
Firmness: Along with the thickness, the firmness of the mattress is crucial. It must be firm enough to support the baby's weight without conforming too much to their body shape, as this could pose a suffocation risk.
Fit to Cot: The mattress must fit snugly within the cot with no more than a 4 centimetre gap between the mattress and the cot sides and ends. A mattress that is too thick might not fit properly, while one that is too thin may not provide adequate support.
Compliance with Safety Standards: Always look for a mattress that complies with the Australian Standard for cots (AS/NZS 2172). This standard ensures the overall safety of the cot, including mattress compatibility.
While thickness is an important consideration, other factors such as the fit, firmness, material, and compliance with safety standards are equally vital. Reading the manufacturer's guidelines for both the cot and the mattress, as well as consulting with baby product specialists or other parents, can provide valuable insights. By selecting a cot mattress that aligns with recommended practices and your specific cot's dimensions, you create a safe and comfortable sleeping environment for your baby, contributing to their well-being and your peace of mind.
