The room is described by its creator, architect Egerton Swarthout, as a large and lofty room, perfect acoustically, dignified in treatment with a semi-circular colonnade of richly-veined marble, resting high upon a marble base.

The Senate Dais (shown at right) is the vantage point from which the presiding officer directs debate and maintains decorum during sessions of the Senate.

The dais, handcrafted and assembled in the chamber as part of the building's original construction, is made of American Walnut. Intricate carvings (below right) depicting Missouri's rich agricultural heritage circumscribe the upper exterior of the dais and the expansive volutes that flank each side in a decorative motif of corn stalks and sheaves of wheat.

The dais is encircled by a wraparound desk made of the same Missouri hardwood. The desk provides a work area for the Secretary of the Senate who is required by Missouri's constitution to maintain a journal of all Senate proceedings, and the reader, who reads aloud the texts of measures before the Senate.

The President's chair, center, is of hand-carved American Walnut. The chair features three-dimensional renderings of bears to complement the Senate clock located above the dais.
