(Have you ever tried barking orders from a sling chair? We're not entirely sure it can be done.) The options below start at a mere $25 and run the gamut from jaunty stripes to an iconic designer print. Scatter several on a patio for hits of color that instantly uplift your outdoor decor. The best part? They fold up flat at summer's end.
