The Office Chair in The Sims 4 features a cartoonish yet functional design with a rounded, ergonomic backrest and a cushioned seat for comfort. It has a five-star base with smooth-rolling casters, adjustable height via a lever, and a swivel function. The materials include a soft fabric or faux leather upholstery in various colors, with plastic or metal accents on the arms and base, giving it a polished, office-appropriate look.
