I suggest mahogany. It's outdoor friendly (used in boat building) and will
last a long time...longer if taken in for the winter. It's also a lot of fun
to work with in the shop.

I would like to make a sturdy swing for 3 people to sit on. Especially
because my wife likes to nap on our deck. I have access to most any wood
for cheap. And I would be taking it in for the winters. But I would like
to stay away from pressure treated lumber.
Thanks,
Dan
