Designers Guild Muara Cobalt Outdoor Decorative Pillow. The perfect cushion for inside and out - a dynamic striped outdoor decorative pillow inspired by vintage hand woven rugs. In gorgeous tones of cobalt blue, with emerald edges, this woven decorative pillow is constructed from a specialist ET polyester yarn. Care should be taken to dry out the decorative pillow and pad should it get soaking wet and water logged.
