Finnbin [1] is a company that sold Finnish style baby boxes in the US up until July 2021. Oddly enough, they appear to have suspended operations due to a US Consumer Product Safety Commission ruling that effectively bans baby boxes.
It appears that the CPSC in the US has decided that it's safer for babies to sleep in objects that can be tipped over (must have legs) than in a box on the ground.
I’m sure the issue is actually that most people don’t want it on the ground, they want it up higher where it’s easier to see, change, and interact with the baby. So people were probably placing the box onto tables, shelves, etc. where the risk of it falling off were deemed too high.
