This cradle is made from walnut and quartersawn white oak. It measures 20 1/4" wide x 21 1/4" high x 34 3/4" long. The construction of this piece was, at times, challenging. Regardless, I would welcome the opportunity to make another one. Perhaps next time with an inlayed design on the end panels.   
Also, as with many of my pieces, this cradle could be constructed of any number of woods, such as maple, cherry, mahogany, hickory, etc.
