Saddle Stringer Stair
Staircase where treads rest on top of a stringer beam.
In a saddle stringer stair — also called a stringer stair — the treads rest on a load-bearing stringer or beam and are not clamped between lateral stringers. The treads project slightly at the front and sides, and such staircases are usually open, meaning they have no risers. The open design gives the staircase a light, modern appearance.
