Yep! I hid a futon in there, in a position that wouldn't clip a character into the wall. (Have not tested it on a Roe yet)
I also finally did a bigger sauna for our FC, and was able to hide showerheads in the wall to get more steam but no sprinkles. The Carby plumbing is hidden in the pillars and the Hingan wardrobes.

Beds nor the chair tricks don't work on the Hingan wardrobes, unfortunately, to sit back there you can only use /groundsit.
