Why buy Puppy Stairs rather than a competitor's product. Puppy Stairs are made from the highest quality materials and are built to last for the life of your pet. Our stairs and ramps have washable, removable covers and are crafted from the finest industrial quality high-density foam unlike other products on the market which are made from flimsy light-weight foam or from heavy awkward materials. On the surface they may seem the same as other ramps and stairs available but because of our choice of more costly materials we are proud to say that we have never had one set returned in 6 years because the foam didn't hold up or because the covers didn't hold up to repeated washings.
