LoveSacs are a well known brand. The “Sacs” that made LoveSac famous are massively oversized bean bags filled with chopped Durafoam and comes with a two-lifetime guarantee never to go flat, or break. LoveSac's latest invention, the Sactionals, is a cross between upholstery and Legos. With lifetime guaranteed wood frames upholstered in foam and fabric, Sactionals consist of 2 simple pieces, “Bases” and “Sides,” that can be combined in any quantity in any configuration imaginable to build any furniture desired—no tools necessary.
