The junction piece: a 36.5-inch square corner that lets L- and U-shaped lounge layouts take shape while holding the cushion line flat around the turn. Seat height is 18 inches, matched to the straight modules. Opal Grey aluminum, with cushions ordered through the contract textile program so a configuration stays consistent end to end. A hundred pounds, the heaviest module in the system and the least likely to move once it is set. Use them to wrap seating around a fire table.
