I have Multiple Sclerosis and am in a wheelchair.  My oldest dog is a Rat Terrier that is 10 years old.  My bed is a high bed which was making it impossible for "Indigo" to get in our bed.  I was unable to pick her up and put her in bed.  Wayfairs Easy Step III was a life safer.  Indigo is one of those dogs that is scared of everything, but training her to go up and down the stairs was real simple.  Thank you Wayfairs.  What a life saver!!!!!
