Simple to assemble, study, does not tremble or shake under weight of pet getting onto it. Nice neat appearance. My dog can now look out of the window while resting on this perch and watch activity on the street! Sometimes I set her snuggly bed on top of it. She likes that too. Planning to use it outside on the patio this summer to keep ants or other ground-crawling bugs off her, and to keep her cool outside. I and my labradoodle recommend Go Pet Black Elevated Cooling Pet Bed/Cot! Good experience with Great Offer Stock.com
