I was really excited to try this sleeper after several reviews. I saw a few reviews with people saying the bed was slanted but I did not pay much attention to it and continued to add it to my registry. I was super excited to receive it as a gift at my baby shower. Once my baby arrived and we placed her in the sleeper, within in 20 minutes her entire body was shifting over to one side!! I mind you she was 6lbs when she was born so by no means was she weighing this down. This product seems like a liability. Very disappointed. We sadly were unable to use this.
