These steps are great for our corgi. The scallops are easy to climb up and down. My floor is laminate and it slips a little bit, but not enough to be a problem. Our dog absolutely loves them and is up and down on the bed whenever he pleases. He doesn't slip on the steps, and its a very sturdy foam so he feels confident using it. This is a great product, very well made. The 30" size is perfect for my 23" high bed.
