Tricky to measure alone but about 6ft at its longest (wider at the top-see pic), 29inches tall and 34inches front to back.
Our bunny did nibble a little on the sides before we noticed and moved it to a different room. He’s a fully trained house bunny, except for the nibbling part!
I took pics without the cushions so you can see the spots on the sides where he nibbled and can see that the rest of it looks fine.
