Generally speaking, the three best places to find cheap furniture around Boston are along Route 9, which becomes Huntington Ave, on Harvard Ave in Brighton/Allston, and at the Ikea in Stoughton, MA (781-344-IKEA)–about 30 minutes from Boston.
However, you can find everything super cheap, albeit in varying degrees of used, on www.craigslist.org. Since so many people are constantly moving in and out of apartments and dorms in Boston, amazing deals may be found on this website by those in a rush t drop their stuff and get out of town.
