Cot mattress reviews

Any sleep surface that’s too soft could increase the risk of Sudden Unexpected Death in Infancy (SUDI). But how firm should a cot mattress be? We assess a range of mattresses from Boori, Grotime, Ikea and more to see if they’re safe for your baby.

Our lab test results show:

• which cot mattresses passed the firmness test, which involves placing a test apparatus at various locations around the mattress and seeing whether it sinks too deeply into the surface
• whether the claimed measurements match up with the actual measurements.

We score a mattress down if the thickness is significantly more than stated, as this could end up being a fall risk depending on the depth of the cot (a cot should be a minimum of 50cm when the base is set in the lowest position, and 30cm in the upper position).

CHOICE is an independent, nonprofit organisation dedicated to helping consumers. Clicking a link will take you to a retailer’s website to shop. While we make money if you buy through some retailer links, this doesn’t influence any of our rankings. 100% of the money we make goes straight back into our nonprofit mission. We’re currently testing this service and will consider providing more shopping links in the future. Tell us what you think.
