Aluminum frame or resin/HDPE chaise — which lasts longer outdoors?

Across the reviewers and pool communities we read, powder-coated aluminum is the most-recommended frame because it won't rust and stays light enough to move. Recycled HDPE/poly chairs are praised for being weatherproof and low-maintenance but are noticeably heavier. Several BuyItForLife and r/pools commenters note that sling/Textilene seats dry fastest, while wicker weaves look great but can be harder to repair once they fail.
