In the cushions we produce, we use reticulated foam formulated for outdoor use. Our resilient and durable foam core and outdoor Dacron fillings are drainable materials which resist the deteriorating effects of the elements. We use outdoor threads. The fabric used on outdoor cushions should be a solution dyed acrylic which resists fading and loss of strength from exposure to the UV rays of the sun.
Cushions can be left outdoors, but we believe they last longer if stored when not in use. And of course, winter storage is highly recommended to prevent wear and tear. Most fabric companies have a 3 year sun fading guarantee.
