This is an exchange for the first mattress I ordered (the Babycalin mark 50x70cm - great product incidentally) is ill-suited to my changing table. I received it today expecting to dimensions of 50 x 65cm. But this does not at all correspond to the description. The product is 60 x 65cm. What is still not adapted to my changing table. Fortunately, the return / exchange policy Amazon is incredibly fast, efficient and free of charge. I Want a third model in the hope that this is the right!
