I currently have a Pet Step and am looking for something lighter and not as thick to store. Solvit is 4 inches thick folded and 13 lbs, PetStep is 6 inches thick and 18.5 lbs. One concern is the gripping surface on the Solvit.
We have had one for probably 3 years. Really like it. I do not know what the Pet Step has for grip, the solvit has a rough surface. It has worn some, but not an issue at this point. Easy to use & store.
