A sewing machine frame is comprised of a vertical support member, a horizontal arm, and a horizontal cantilevered base member, each of which is comprised of a hollow, rectilinear aluminum extrusion. The vertical support member is secured to a horizontally disposed base and the arm and bed may be secured to a side of the vertical support member or the vertical support member may be divided into first and second portions with the first portion interposed between the arm and the bed and the second portion being interposed between the bed and the base. In the latter construction, common bolts secure the arm, the bed, the base, and the first and second portions of the vertical support member together as a unitary assembly.
