Rail is a clever design for a modular table system. It’s based on trestle legs that can slide along the length of the table’s underside, thanks to rails and grooves.
This means that you can slide a pair of legs out to the edge of the tabletop, and connect either a short extension or an entire other table. A cam lever secures the connection.
Both rectilinear and trapezoidal shapes are offered for the tabletops, which are available in Oak or American Walnut.
The podium-like desk in these photos might be confusing…
…but it’s a separate add-on that can be placed atop the trestle, between two tabletops. The assembly video below makes it a bit more clear than the photos do:
Rail was designed by Studio Kaschkasch and is in production by furniture manufacturer Zeitraum.
