A center seam allows the leaf to fold and stack to slide under the table top for storage. Our Amish artisans have perfected the mechanism of the leaf and also minimized the space required making it virtually invisible beneath your table top. When installing the leaf for use, one need only to separate the table top by pulling the ends apart, then lift the top half of the leaf to open and the mechanism allows the leaf to rise into place. Finally, push the ends of the table back together so that the leaf secures snugly on either side. Now you have two extra spaces at your Amish dinner table.
