Ryan - The top is plywood with ~1-1/2" wide pine edge banding w/ a bullnose routed edge.
schaffer - the overall dimensions are 64-1/2 wide x 23 tall x 20 deep. The width was designed to match the dimension of the TV cabinet. The height and depth were basically derived from the old stand that I was using temporarily. In truth, it could stand to be about 2" deeper to fit the receiver better, but it works fine.
Art - one of my favorite quotes is from Robert Heinlein: "A human being should be able to change a diaper, plan an invasion, butcher a hog, con a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, and die gallantly. Specialization is for insects."
