Hi. Will the airiest cot mattress (standard size) fit in this cot? Thanks

Hi there, the Lolly is a standard size crib, we recommend the Pure by Babyletto line of hypoallergenic and eco-conscious crib mattresses. The recommended Mattress Size is 71 x 131cm and less then 15cm high. The Airnest Cot mattress (standard) dimensions are – 69 x 130 x 12cm.  The mattress must fit the cot firmly. Any gaps at the ends and sides should be less than 2cm, so we would not recommend using this mattress with this cot. Hope that helps
