The elevator landings have green terrazzo floors, travertine walls, gray elevator-door surrounds, and gypsum ceilings. The remainders of the office stories used modules designed by Hauserman. The elevator doors, suite doors, and partitions were designed to rise from floor to ceiling, which made the openings appear as though they were part of the paneling. Partition panels were designed with washable materials, which became standard after they were used in the Seagram Building. Doorknobs were made of lever handles instead of round knobs. The interiors were also decorated with numerous artworks, including the Seagram murals by Mark Rothko, which were intended to sicken the patrons of the Four Seasons Restaurant.
