This Bistro chair cushion has been specifically designed for outdoor use, and will add an extra special touch of comfort to your Bistro furniture. It features an Outdoor Technical Fabric outer layer, which is resistant to tears and inclement weather conditions (sun, rain, humidity), and a closed-cell foam filling which keeps the cushion watertight. It can easily be cleaned with soap and water. It has clever elastic straps for excellent hold to the seat, in both the folded and open position.
