When built, the tower section featured granite floors and metal interior furnishings, though there was very little wood trim, unlike other contemporary structures. The lower floors contained bronze grillwork and doorways, especially around the elevators, while on the upper floors, ornamental iron is used for the metalwork around the elevators. The second-floor spaces contained offices of the Metropolitan Life Insurance Company and contained white marble wainscoting, plaster cornices, marble mantels, etched-glass doors facing the executive offices, and red mahogany door, wall, and window panels. Each of the tower's floors are up to in area, smaller than the floor areas of most other nearby office buildings. During the 1960s renovation, the tower was fitted with more modern furnishings such as air conditioning, acoustic ceiling tiles, and automatic elevators, to match the new eastern wing. Marble floors were one of the few holdovers of the previous decor. The staircase leading to the top floors of the tower also retains its original decoration, including cast-iron railings, ceramic-tile wainscoting, marble stair treads, and landings with mosaic-tile floors.
