This is certainly out there, on the weirdness scale, but TakaraTomy have put up on their site, a pattern you can print out, which can be cut out and glued together to create a couch for your Microns to sit on.

It even comes in two colours - orange/Autobot and purple/Decepticon.


Apparently it is actually from the Arms Micron shorts in Japan, which I haven't seen, but if true, makes it a canonical prop.
