We bought the mattress due to the good reviews. In many reviews I've read that the mattress smells strongly and had fears, like our well smells when she's there. I can only say that the mattress smells absolutely nothing and can be used immediately. Here we have the mattress ordered in the wrong size. Ravensberger has to be picked up the wrong with us and provided us with a new one. And all for free, although the Verschulen was with us. My conclusion: Highly Recommended !!!
