This has to be one of the best sleepers I have used. My baby will not sleep in a bassinet but absolutely loves this one! It is so much easier to get the baby out of it in the middle of the night, I also love how I can but it right up to my bed! It has mesh sides to it's very breathable. My baby doesn't wake up often now that she is sleeping in this. I love it! The quality is made really nice.
