Seems sturdy after 10 months of use in a kitty Foster room,  however there are dangerous staples sticking out.  I removed several staples with pliers when I felt them with my fingers. Unfortunately there was a sharp end of a staple sticking out of the top that I didn't notice recently and a poor Kitty sliced his paw on it. I wish I had noticed all this and contacted them within the first 30 days so I could have returned it and gotten a refund
