My grandkids ages 4 to almost 2 years old use this step stool. My four year old Grandaughter and almost 2 year old grandson use it to get up on my bed or to use bathroom sink or toilet. Last night my Grandaughter went to get up on my bed using this step stool. Stool collapsed and she hurt her left side of leg falling. After tending to her injury and crying. I picked up stool and there was cracks through the sides below the base. Very upsetting considering it claims it holds up to 300 pounds. This product needs recalled. Fortunately no bones broke or any other injuries! Very traumatizing for her.
