we have purchased several types of Adirondack- Cedar, Polywood etc. These are the best (and the significantly less expensive than Polywood)  They are a bit of a pain to put together, up to an hour, but once together they are solid. We have assembled 8 of these now - had no issues with holes not lining up, missing parts etc.  By far our favorites. comfortable , easy to clean. We leave them out by the water and know they won't rot.
