While both are equally sturdy and safe, there are some differences between these two towers. The Convertible Helper Tower has the option to convert into a table and chair, while the Foldable Helper Tower does not have this feature. The Foldable Helper Tower can fold for easy storage. Another feature of the Foldable Helper Tower is an adjustable standing platform (3 height options) adjusting as your child grows, while the Convertible Helper Tower only has an adjustable step (3 height options) which is used as a seat when the tower converts into a table.
