This is my favorite place in Pittsburgh.\n\nThe Mattress Factory is an installation art museum with exhibit tours that rotate through it.  Different artists do residencies there.\n\nThere are also some permanent exhibits, all of which are extremely cool! I don't want to go into too much detail, because I don't want to spoil it, but you'll definitely enjoy your time there.\n\nIf you haven't done the Mattress Factory yet, go do it now.
