These steps feature all the benefits of our Single Pet Step, while providing access to higher areas. It is a perfect solution for tiny breeds and older animals, and for pets with injuries and other disabilities that restrict their jumping on and off furniture. The step can hold up to 300lbs! You can also order a non-slip bottom for the pet step that will prevent movement on tile, linoleum or hardwood floors. Features: Size: 18.5" Wide x 22" Deep x 14" Tall. The single pet step is made of plywood and kiln dried fir, NOT particle board or cardboard, as it does not hold up well. The carpet is high grade, 50 oz. or better. This pet step ships Fully Assembled.
