In theory, I could probably put a full size frame in the Kid Cave, but I would have a mutiny on my hands as that’s where the X Box, the big TV and the surround sound are. It’s also where the kids have sleepovers.
I remember when I wanted a big sewing room other then the tiny room I was using. DH had a big shop for himself. I took over the den, had a barn door put in to close it off. The kids were not happy I took over their space ? As I told them your home but my house and your permission is not needed. Watch tv in living room or or set up in dad's shop. LOL He of course put a squash on that idea.
