Review on Sturdy Folding Step Stool: Lightweight and Safe for Kids and Adults | Easy One-Flip Open | Ideal for Kitchen, Bathroom, Bedroom, and More by Byron Patil

Although the instructions on the stool say it snaps into place, it doesn't. There is no lock. You can lift this stool or trip your foot over it and it folds easily by itself. I bought this for my 3 year old to use by the bathroom sink but I'm worried it will collapse if it moves slightly when stepped on and could seriously injure himself. I do not recommend this for children. It would probably be okay for an adult to use it on carpeted surfaces.
