Two layers of MDF, I don't remember if it was 1/2 and 3/4 or two layers of 1/2. You can get easy to handle 1/2 pieces at HD you don't have to buy a 4x8 sheet. On the 3/4 you can grab a pre-cut shelf board.
The top detail is a molding called base cap, upside down
The bottom is 1/2 round.
I would have bought all at HD/Lowes. as that is the nearest locally.Edited by BIGmouthinDC - 5/3/13 at 6:04pm
