I have one that is meant to double as a porta-a-cot (no mattress though - grrr) and has a UV50 roof that can be attached when put outside. It is also meant to be hosable if it gets dirty.

Maggie did not seem to like it, only occasionally was she happy to go in it for more than 5 minutes. I probably did not persevere enough, but I really only wanted it for times when I had to leave the room. In the end it became a toy dumping ground, so I put it away. It is becoming useful again now as a cubby house, as I can put the roof up and it has a little door that unzips in the side.
