Learning tower or simple step stool — which does my toddler actually need?

Across r/toddlers, r/Montessori, and r/NewParents discussions, the consensus is that learning towers (enclosed standing platforms) are safer for younger toddlers around 18 months to 3 years who want to help at counter height, because the rails prevent falls backward. Simple two-step stools are widely recommended once a child is steadier on their feet and mainly needs to reach a bathroom sink or toilet. Many families end up owning both.
