The adirondack chairs we carry are made out of marine grade polymer. They can be left outside all year round. The hardware won't rust and the color of the chair will not fade. These are chairs that are meant to last. I myself have a pair of Telescope casual adirondack chairs that I have left outside in 2 of the harshest winters we've experienced, yet, I could power wash them and sell them to you as brand new. They really are that durable. Some people are a little sticker shocked when they see the price BUT so many things these days have an expiration date and it's not usually far off from the purchase date. Buy it once because, as the saying goes, you get what you pay for.
