Anybody tried one of the garden benches made of some kind of resin material? I was considering one for use in a shady garden area. Several I saw had too much decoration, but I saw one at a Kohl's store that was a little simpler. I like the "sit" of it and the fact that it was heavy, but movable; I'm just afraid it will look too fake. I thought I could naturalize it somewhat with plantings around the edges. Do they hold up under full outdoor treatment? Wonder if I should just try to find a very simple plain concrete bench instead.
