After a lengthy search, I ended up purchasing these steps for our 10-year old chocolate lab to get in and out of our SUV.  After much coaxing she finally went up them to get in but refuses to use them to get out...she jumps right over them! They are easy to assemble, sturdy and lightweight. I am very pleased with these steps. They DO have a slight upward slant to them but I don't see that as a downfall.
