In a mortise and tendon stairway design, the stringers are parallel half logs that hold the treads in place.  A mortise (hole or space) is cut into the stringers to exactly match the end of each individual stair tread. The tendon is the part of the stair tread that is inserted into the mortise. This joint is one of the oldest proven construction methods. This style of staircase is shipped to you fully assembled for easy installation.
