The Lisbon Sling Collection sets you apart from the rest. This classic collection features traditional-looking solid cast aluminum. Its timeless motif with fanciful swirls and scrolls evolves into a focal point that features an architectural-style finial. The Lisbon Sling Collection is simply stated with a broad and robust design. Telescope offers five super - comfortable "elastomeric" fabrics. These fabrics feature a technologically advanced elastomeric monofilament that contours to your body for extra comfort and then returns immediately to its original shape. Due to special design considerations with these advanced new fabrics, we are only offering them on our Romanesque, Lisbon and Savona Sling Collections at this time. 15 year residential warranty
