Abstract: A modular furniture retaining system for maintaining a static relationship between multiple related pieces of furniture. The modular furniture retaining system includes a first piece of modular furniture, a second piece of modular furniture, a first magnetic coupling assembly and a second magnetic coupling assembly. The first piece of modular furniture includes a first side and a second side. Similarly the second piece of modular furniture includes a third side and a fourth side. The first magnetic coupling assembly has a first polarity, and is positioned on the first side of the first piece of modular furniture. Similarly, the second magnetic coupling assembly has a second polarity complimentary to the first polarity of the first magnetic coupling assembly. The second magnetic coupling assembly is positioned to align with the first magnetic coupling assembly when the third side abuts the first side.
