I think furniture in the garden gives the whole area a nice appearance. If there is room on the lawn, a nice bench in the middle of the lawn, or 2 benches for that matter, is good, not only for the general appearance, but also for sitting out and relaxing. My neighbours have benches on their lawn and I sometimes see them out on the benches relaxing with other folk. It is a good idea, but so far, we have no benches in our garden, although there is ample room for such. We actually have a concrete area next to our garden, that holds a few plant pots around the sides. A bench would look perfect on that concrete area. One can sit out in their garden and read a book, or just sit out there for the sake of it, and relax while enjoying the outdoors.
