The show focused on the Huxtable family, an upper-middle class family living in a brownstone in Brooklyn Heights, New York, at 10 Stigwood Avenue. The patriarch was the very playful, humorous, and fun-loving Heathcliff "Cliff" Huxtable, an obstetrician. The matriarch was his very eloquent, elegant, and assertive wife, attorney Clair (Hanks) Huxtable. The show involved the usual difficulties of children growing up, such as son Theo's experiences of dealing with dyslexia, which was based on Cosby's real-life child Ennis, who was dyslexic.
