Nice, heavy, well-made chairs.  However, the seat is not wood.  It is a solid piece of hard plastic or some other material and is made to look like wood.  It is completely smooth, which I guess is good for not getting splinters in your tush as you might if sitting on real "weathered wood."  This is not what I was expecting but it's not a problem- it actually makes them easier to clean.  They are solid and don't slide easily.
