While the vast majority of married couples in South Korea sleep together in the same bed, a notable minority—particularly among older generations or couples with very young children—occasionally sleep in separate beds or separate rooms. This practice is often driven by practical lifestyle needs rather than marital discord, such as accommodating different snoring habits, contrasting work schedules, differing thermal comfort preferences, or allowing parents to sleep undisturbed near infants and toddlers. As modern housing designs change and younger generations adopt contemporary westernized bedroom layouts, sleeping together remains the prevailing standard across the country.
