Rob, plywood is seldom used for dining room furniture, at least for chair backs. Could you please post a photo of the type of chair you want to build and then we can tell you the process. If this is for a normal chair back and you wanted it laminated for strength you would build a form and then clamp thin layers of wood and glue to the form to create the shape. While this seems like plywood it isn't by a long shot.
