The Easy Step Pet Stair has wide, deep steps to give smaller dogs the ability to get their entire body on each platform and large dogs the ability to comfortably climb the stairs. The innovative incline of each step reduces the amount of stairs needed to climb eliminating stress on your pet. The carpet tread removes easily and is machine washable. The stair easily snaps together (no tools required). Available in 2, 3 and 4 step sizes along with a variety of colors.
