Saddle staircases are staircases of classic style. The supporting element of these staircases are carved strings (sidewalls) on which scales are attached from above. The risers, if any, are embedded in the scales.
These staircases can be produced both closed with risers and open without risers.
The railing is mostly all-wood, but can also be stainless steel or a combination. Of course, glass railings are also possible.
