I’m not sure if mine is defective but it is extremely not level and my newborn always ends up sliding and bunch up against one edge during the night which is extremely unsafe. This occurs even when the bassinet is stationed in the central position and I have verified that my floors are perfectly level that it is sitting on. I am losing so much more sleep because I am constantly waking and readjusting her because I am so nervous.  Seems like a huge waste of money for something so unsafe.
