Why is wall attachment so important for the Billy Bookcase?
Wall attachment is critical because serious or fatal crushing injuries can occur from furniture tip over. The Billy Bookcase must be used with the wall attachment device(s) provided to prevent tip over accidents. This is a mandatory safety requirement, not optional.
