Thanks Everybody,

Splint - The tops are 8/4 Walnut , black stain, Pre-cat (dull rubbed) finish

BB1 - Yes the stools will be under the middle section.  Although, on the right side will be a black piano, so I figure the stools will be pulled out but probably face the piano when being used.  
I'm going to make the bases for the stools but the upholstery will be done by someone else.

Figuring out how to do something you have never done is what makes a good challenge.
