Love this product. It is VERY sturdy, was easy to assemble myself, and all the pieces came together so well it allowed the cage to be built strong. All the pieces came in great shape. Our Mini Rex thoroughly enjoys it. 
Please remember that rabbits chew wood. So if you have a rabbit, they will likely chew on this. It’s wood!!! Which I was well aware of when this item was purchased. As I was also aware of measurements and did my homework on the space I wanted it to be set up. 
I’m very satisfied with this purchase and love Wayfair! They’ve always been good to us!
