We have recently been gifted a tutti bambini cozee crib and have bought a LGS replacement mattress based on the good reviews. However, I have just tested fitting the mattress in the crib and it is 2cm smaller in length and 1.5cm wider than the manufacturer mattress - is this an issue? It says on the LGS website that it is to fit this crib and the mattress I’ve received is made to the spec on the website. After some advice on if I am worrying too much as an anxious soon to be first time mum.
