I purchased these steps to replace the standard ladder for our pool. NONE of the pieces are numbered. It took about 4 hours to put them together. Once ready to install you will need a person in the pool to help set the steps in place. There is no pad or liner protector included. I purchased this just as a precaution and to protect the pool liner. I wished the gate swung open further. It tends to close on you while climbing up and down the stairs. Overall, they are sturdy and serve the purpose.
