Thermoplastic resins consist of long molecules which be repeatedly melted and solidified by heating and cooling. Compared to plastic furniture, resin furniture is stronger, more durable and more resistant to salt, chlorine and suntan oils. A UV coating gives protection from the sun and, like timber, cast resin remains cool to touch in hot sun. Visually it can be difficult to distinguish resin furniture from painted wood furniture, which it is often designed to resemble. The famous Adirondack chair, for example, is available in either resin or wood � with the latter completely resistant to rotting, warping, cracking and splintering. It can remain out of doors year after year without discolouration. Good quality furniture is fastened with stainless steel fixings. Resin furniture costs more and last longer.
