It gets its name from the horizontal spindles that serve as the back support on them and are reminiscent of a ladder.
Between these two uprights exists multiple horizontal spindles or slats (three in the picture to the right).
Ladderback chairs date back to the Middle Ages where they can be found in homes across Europe.
By the middle of the 17th century, luxury furniture makers began to make ladder-back chairs out of walnut, rather than the more common sycamore or maple and added refined decorations and engravings.
Meanwhile, the slats along the back of the chair required several different sizes of saws and a plane.
