Sunbrella Sling Focusing on subtle patterns that read like textures, Sunbrella Sling allows you to achieve elevated interior aesthetics in an outdoor setting. Unlike traditional rigid and uncomfortable PVC strapping, Sunbrella Sling combines the strength of PVC with the softness of Sunbrella acrylic yarn for enhanced comfort. Mixing natural color palettes with innovative yarns for added texture and luxury, Sunbrella Sling is ideal for creating fully upholstered outdoor furniture.
