Easy to put up, great for indoor play. My 1 year old son loved it when he received it, and still does 6 months later. My dogs also like to think of it as a big dog house. I sometimes remove the tunnel and collapse it to save space, so that's really a nice feature. It's a cute way to give the little ones a small space of their own while still being in the room with you. Also has helped some gross motor skills with crawling through the tunnel and learning to duck in and out of the front door. Would recommend to someone who has the space to have it inside in a play area.
