Uneven, curvy paths and less-than-ideal site conditions can delay the installation of outdoor seating. Tangent Rail Seating from Forms+Surfaces can help. It accommodates nonlinear paths with an articulating rail that can adapt to an inward angle of up to 20 degrees and an outward angle of up to 45 degrees. A flexible connection enables a zigzag, curved, or linear layout. Choose between either powdercoated aluminum slats and FSC-certified Ipe or stainless-steel, perforated seat pans for seating options. forms-surfaces.com
