Due to my sizable Transformer collection, I actually have no room to display my MU & Joe figures. I keep them individually bagged in a zip-lock with all their accessories inside a rubber/plastic tub. They don't really weigh enough to do any damage to each other, and the little bit of air that gets trapped in the bags provides a bit of cushioning. The air does leak out eventually but it's slow enough that the figures don't get damaged as they settle into place.

I do the same with my excess TFs, but I usually transform them into the most compact mode I can get them into. I've had quite a bit of my TFs packed up for the better part of a year and a half and none of them have been damaged that I have noticed. I don't jostle the tubs around much though either, so they pretty much just stay where I put them.
