Love this product.  I have 5 Boston Terriers and have beds and crates in various places.  I got this to replace a homemade tent w/ a dog bed in it.  The shelves give me room to put the treats that we used to keep in a storage stool beside the tent.  It makes the room look so much neater.  It's very heavy and took a long time to put together.  It's definitely a 2 person job.
