looking for a bench like the one in this photo I would suggest an antique shop. This one in particular was given to my client from a relative in which we selected the table and chairs set to match. Good luck.
It's a man made product, but the finished look is more like a dry stacked natural stone. It comes in 2-3 colors.

Vallarta are a great example of the natural, earthy style that the tropics offer. This side of Mexican decor is easily translated into a more staid and colonial look.
