Designed for supporting casual gatherings and making perimeter spaces useful for collaboration, the Flex Mobile Three-seat Sofa features a thick seat cushion and 10" high padded back to make a brief touchdown painless. Cushioning is made with hybrid soy-based, CFC-free foam. Double-needle trim on full upholstered seat and back reinforces sewing to withstand frequent use. Maxwell Shoreline seat fabric and Blip Gecko back fabric are made of polyester with recycled content. Both have a stain-resistant finish without PFOA (Perfluorooctanoic Acid) to serve you longer. Metal-to-metal connection of seat and back ensures long-term durability. Twin-wheel, locking casters in place of the glides allow greater flexibility in moving and reconfiguring seating and meeting spaces. Casters work well on carpet or hard floor surfaces. Seat measures 60" wide x 20" deep x 18" high.
