Abstract

This application pertains to the furniture technology field, providing an assembled sofa comprising at least two seat frames and two first connectors. Each long side of the seat frame has two spaced first mounting grooves, while each short side contains two spaced second mounting grooves, with identical spacing between first and second groove pairs. The first connector includes a connection section, two engagement portions, and two hook portions. The engagement portions extend from both ends of the connection section. When adjacent seat frames abut each other, the connection section bridges both frames with engagement portions secured in either first or second mounting grooves. The hook portions contact groove walls of corresponding mounting slots. This configuration enables simplified sofa assembly through interlocking components.
