Truly one of the best purchases I have ever made! I've purchased pet stairs previously only to find I wasted my money on cheap products that arent functional! The best thing about these pet stairs are the soft flexible pet friendly fiam steps. Plus you can remove the zippered cover and wash it. The size is perfect for our living room furniture and bedroom furniture. Best of all ? Our dog loves them. It gives our fur baby a new independence. If I could rate this 100 stars I would. You can even adjust the height if needed
