This is exactly what I was looking for for my large dog in our small house. I use it as a coffee bar and it's so sturdy nothing gets moved or knocked down when my dog is in it, and he is 85 pounds. The doors are a little annoying if you're impatient and open or close then too fast, fall off their track, but they easily go right back in. I built it myself and the instructions were easy to follow. It is big, so be careful when building. My dog loves the extra room, but also snug space.
