Footrests are devices designed to elevate and support the feet while sitting. They can be used to improve posture, reduce pressure on the lower back and legs, and enhance overall comfort. Footrests come in various forms, including adjustable and non-adjustable models, as well as those with built-in massagers or heaters. Some footrests are made of soft materials like foam or memory foam, while others are made of more durable materials like plastic or metal. Footrests are particularly useful for individuals who spend long periods sitting, such as office workers or those with mobility issues. By using footrests, individuals can improve their sitting posture and reduce discomfort in the lower body.
