Disclosed herein is a joiner (10) comprising an elongate body (12) defining a longitudinal axis (14). Projections (16, 18) extend generally transversely from the body (12) at opposite ends thereof and two spaced apart magnets (20, 22) are located between the projections (16, 18). The magnets (20, 22) are adapted to magnetically connect the joiner (10) to ferrous metal anchor points (i.e. the frames 101, 201) of modular furniture to retain the projections (16, 18) in engagement with the frame of the respective unit of modular furniture (100, 200) and thereby to retain the units of modular furniture together.
