Sure, you could sit on this giant polyethylene Qoffee stool from designer Rainer Spehl -- after all, that's partly what the thing is designed for -- but you could also flip it over to store toys, plant flowers or play hide and seek, among other fun activities. And with all the panic about BPA, phthalates and other potential toxins, it's nice to have a cheap* plastic cup do something more than leach chemicals into our drinking water.

* "Cheap," by the way, is a figurative term -- the Qoffee stool will cost you 55 Euros, or around $84 U.S., via overseas order from Artificial. Other retailers carry it, though delivery ranges vary -- try Googling for the best value and shipping beforehand. [Via Minor Details]
