The Penn Plax 3 Step Carpeted Pet stairs provide a lift to both cats and dogs up to 150 pounds. These steps help smaller, elderly, or pets with medical issues reach their favorite spot by giving them a lift. Place these pet stairs near a bed, couch, chair, or even a car and watch your pet climb on their own and grab a seat. These steps help to protect your furniture from damage when pets keep jumping up and down and accidentally scratching with their claws. These pet stairs are wider and less steep than our competitors, offering more room with an easy up and down. Made of quality engineered wood, these steps are strong and durable. Pet stairs measure 12.75 inches high by 14.75 inches wide and 18.5 inches deep and are suitable for both cats and dogs.
