Rabbit furniture in sheds etc

Hey guys, please can I have idea of what kind of things to put in the shed for Dude and his soon-to-be giant wifey?

I've thought kiddies table/chairs (plastic) ... but I can't think of anything else!

Would obv have to be sturdy enough to support a giant's weight.

Thanks in advance!

I have a large dog crate stuffed with hay which they love,OH also made a large long box that they can sit in or run through and also sit on top of.

Well...she loves laying on the sofa lol! And going on the windowsill.
Anythin she can climb over/under/through really is all good.
