The Snuggle Nest folds into a backpack and there are pockets you can use to store a few baby essentials. Is it best used for travel, when you most likely need both hands to tend to the baby and carry other stuff.
One side of the wall lowers down and locks, best for attaching beside the bed for nighttime sleeping. During day naps and when you are not in the same room as the baby, you can secure all four sides by pulling up the wall.
This works fine for average 25-inch tall beds but if yours is shorter, this co-sleeper will not be at the same level as your sleeping surface. If your bed is taller you can buy leg extensions or get a different Arm's Reach Co-Sleeper - the Euro collection is for shorter beds.
With other options like the Bassinest, you'll need to pull the arm down in order to reach your baby which is not that easy to do with one hand. With this co-sleeper you can just scoop up your baby without any mechanics involved
