I've been wanting resin Adirondack chairs for years because the cheap Target plastic ones are, well, just damn cheap. And my wood ones fall apart within 2 years, even when I weather proof them.
Today I finally found some I can afford. Costco has the Lifetime Adirondack in a sandy wood color for $109. Retail on these bad boys is $171-250. They are similar to the popular Polywood brand (minimum $299 a pop) in that they are made from polystyrene plastic with UV protection. Polywood is the "brand" name but this is a great alternative. The color was very nice: didn't look too wood fake. Reviews are all excellent. These are B&M as I didn't find them on the Costco website. For reference:

From the Lifetime website: "The Lifetime Adirondack Chair is constructed of UV-protected polystryrene so it's weather resistant and will look as good as new throughout many years of outdoor lounging. Get the warmth and charm of a wooden adirondack chair without the splitting, splintering, or maintenance."
