Vitra really makes several of these "Big Table Desking" systems but I think Joyn is my favorite. First is is the most open in terms of feeling like a big table - there are no predetermined horizontal divisions and you can make each work station as big or small as you wish. It also has the power and accessory rail along the center which gives each workstation as much utility as a cubical. And it has legs with a saw horse vibe!

Joyn is more than a piece of office furniture. Joyn is the office – and also a management tool in a time of cultural change. Joyn condenses a diversity of spatial functions on a single plane: the platform. With its mobile and modular structure, Joyn adapts spontaneously to changing demands and technologies. It initiates new, productive forms of work based on communication and co-operation.
The decisive factor for planning a Joyn configuration is the number of required workplaces. This determines the number and size of platforms to be used. The Joyn platform is the central unit of the system. With a wide range of practical accessories and sophisticated solutions for power access and wire management, Joyn is an extremely flexible system that can be easily reconfigured. Joyn is simple to use but as sophisticated and complex as the problems it helps to solve.
