Pottery Barn kids is really a joke. I do like their products, but what is it worth if you never get the right items plus Customer Service is not helpful at all. We gave them 3 chances to deliver the correct mattress and we always got the same wrong one.
We always had to store the wrong item, we had to spend hours on the phone with Customer Service, plus our sleeping situation was a construction side, as we were waiting for the right mattress to arrive. Well I am done with that shop and will never ever buy anything there again.
