A nested bassinet with mattress is an essential piece of nursery furniture that allows parents to keep their newborn close while maintaining safe sleep practices. These innovative bedside sleepers attach securely to your bed, providing convenient nighttime access for feeding and comfort while ensuring your baby has their own designated sleep space.

Check that the bassinet's mattress is firm and fits snugly within the nested design with no gaps around the edges, as loose-fitting mattresses pose suffocation risks and defeat the safety purpose of the bassinet structure.
