I used pine for this cradle and there are five pieces, two ends (the 'headboard' is larger than the 'footboard'), two sides and a bottom.
The ends are attached to the sides with wood screws and then covered with wood plugs, the bottom is glued with a few finishing nails along the sides.
My customer wanted this painted so I used a good primer and then painted the cradle with a white interior semi-gloss paint.
I hope the little recipient of this gift enjoys many hours of play with it.
