Sleeping in business class in 2026 is a refined experience thanks to lie-flat seats and premium bedding. To maximize rest, start by adjusting your seat to the "bed" position and utilizing the provided mattress pad for extra cushioning. Many airlines now offer "turndown service" where flight attendants set up your bed with high-thread-count linens. Use the noise-canceling headphones provided, or bring your own, and pair them with a high-quality eye mask to block out cabin light. It is also helpful to change into the complimentary pajamas offered by many carriers to signal to your body that it is time for rest. Avoid heavy meals and alcohol right before sleep; instead, opt for the herbal tea service. Most modern business class cabins also feature individual climate control or air vents, so adjust yours to a cool setting to mimic a natural sleep environment.
