Non-Standard Crib Mattresses?

[bittenkitten]

Hello everyone,

We've recently been given a lovely crib by a family friend. I checked carefully and it does meet the most updated crib safety standards, but the problem is that it won't take a standard 52" crib mattress, only one that is 48" long. Does anyone know where we can get one of these mattresses?

Thanks so much in advance!
