A furniture assembly and/or a mechanical coupling system for coupling furniture parts together to form an assembled article of furniture. The furniture assembly may include first and second furniture parts, each of which includes a board or other structural member and a coupler. The first furniture part may include a male coupler attached to the board and the second furniture part may include a female coupler attached to the board. The male and female couplers may be coupled together to thereby couple the first and second furniture parts together to form the assembled article of furniture. The male and female couplers may include engagement features that facilitate the coupling of the furniture parts together and to prevent them from becoming detached during normal use of the assembled article of furniture.
