Homes are no longer anchored but travel with us like basecamps trough towns and countries. Most of our furniture is not compatible with such lifestyle. Every time we move makes it easier to trash it and then buy a new one that's delivered next day to your new address. "Ballast" is a three- seater sofa that can be built up and down faster, than you can check out your shopping cart online. It is the skeleton of a sofa, where the core functions are fulfilled and the rest can be added by the user.
