We got our new king size head board, the frame is solid pine construction, but the panels are plywood.  Also it arrived chipped on one of the legs, but I was on the inside and would never be noticed so we didn't worry about it.  Finally the holes drilled in the frame were drilled too high to easily attach the bed frame, we ended up having to shim the bed frame about 3/8 of an inch to get the bolts that were not supplied to line up.
