Great quality. Sturdy product. We hoped this "cave/crib" would help my anxious 55 lbs pit bull/Shepherd mix with his separation anxiety when we left. He has long legs and he has to belly crawl into space. We are leaving lid open for now so he can jump in and out easier. We plan to install some legs on the bottom so it'll be easier for him to get in with lid closed and it can also be a place where he perches to look out window. My 50 lbs Chow/Golden mix also loves jumping into it and curling up.  Once inside they love it. There was space for an extra pillow, blanket and softer mat. I knew I was risking it being too small for my pups and I do wish it were a bit bigger but I'm still happy with product. FYI- the mat it comes with is black, not navy like picture suggests on my screen
