It is 48" x 32" X 16". The base is made from hard white maple and the top is made from some of the nicest walnut boards I have ever seen. They were 10" wide x 10 feet long. I have some more that are 12" wide x 10' long and all (not mostly, but all) heartwood.
The bottom shelf is made from maple boards that float between the stretchers. The brown stain is from a wormhole. You can't tell from the pictures, but the bottom shelf really is flat. I radiused the edges of every board in the table using a router table and a 1/8" roundover bit. I didn't want anyone to hurt their foot on it. It is 16" tall, which is short for a coffee table by about 2 inches. That is the right height so that everyone can rest their weary feet.
Now I'm working on a TV stand, and then I'll do another coffee table 48" square to finish the set.
