Buyer Beware...Purchased the Solvit PupSTEP XT Pet Stairs, which are horrendus. They supposedly can support 250lbs., but my 40lb dog was afraid to use them. They are incredibly flimsy and cheap...DO NOT BUY!When we called AbsolutelyPets to complained, they were unsympathetic. The product came pre-assembled and without a package, unless you consider the shipping box. Because we opened the "package" we would have to pay for the shipping and a 20% restocking fee. They do not stand behind their products...I will never purchase a thing from them again!
