We have a new born that we wanted to co sleep with but it was hard to accomodate all three on the bed. This bedside sleeper is amazing which gives us a feeling of co-sleeping yet the baby sleeping in the bassinet. This sleeper attached right beside the bed. It is very portable and space saver. It keeps my baby cozy and close to me and yet comfortable. I feel that my baby is safe sleeping in this sleeper than the bed. It is also great for nursing moms as the baby is at arm's length at night. The sleeper was easy to assemble and is very sturdy. I highly recommend it.
