Heavy-duty overhead luggage with a chest of drawers and a seat

I've never tried the Zuca Pro ultraluggage, but the heavy traveler in me responds to it in an absolutely visceral way. It's got a built-in seat and internal, stacking drawer-like sub-luggages, and it fits into overheads. If only I hadn't sworn off two-wheeled luggage for four-wheeled spinners, I'd seriously consider this thing.
