For the madison collection, we began with Sunbrella's new premium Natte Italian fabric, available in canvas or graphite that is water and UV-resistant. Underneath is a top-grade reticulated foam wrapped around a powder-coated aluminum frame. We mount this on 304-grade stainless steel legs. The seats are comfortably slanted to the back and open at the seat to shed water. The cushion bottoms are open mesh underneath for breath-ability. The aesthetic is 1930s Bauhaus but the materials and construction are strictly 21st century. Supremely comfortable, durable, low-maintenance and a great value.
