I had bought mattresses on this site to the dimensions of my baby's bassinet, but the elastics were so tight that my original mattress became deformed. So I bought this mattress, much thicker. The problem is the same. So I stopped using the mattress pads. My baby regurgitated and the mattress was stained, so I washed the cover at 30°C as indicated on the label. Unfortunately it became deformed and also caused a minor deformation of the mattress. I am disappointed with these purchases.

Just received this product, I washed the cover (respecting the washing instructions on the label), and what a disappointment: the cover has shrunk drastically, making it unusable.
