What is everyone's opinion of making Bonsai benches out of the plastic lumber that's regularly used for decks? It's pricier, but I figure I don't have to worry about weather treating or warping at all...

Also, has anyone made themselves a multi tiered bench, almost like steps? I was thinking of doing a 3 layer bench and wondered if anyone has done one similar... I'd love to see a picture if possible.
