Snuggle nest..

Anyone uses one of these?  We arent co-sleeping, I sleep in the baby room so hubby can rest - his work hours are demanding.. I wonder if anyone uses snuggle nest ..me and baby sleep on the floor in baby room - she is too small for her crib and I had a CSection, so floor is more convenient.   My baby girl wiggles and turns on her side alot -  i woke up the other day to see her too close to the side wall of the snuggle nest - It scares me now to use it..there is a "breathable mesh" liner on the side but Im not sure if its entirely safe.  Any advice is appreciated.
