A footrest is a piece of furniture designed to support the feet while sitting. It helps improve posture and comfort, especially during long periods of sitting at a desk or in a chair. Footrests can be adjustable or fixed in height and may come with features like cushioning or non-slip surfaces. Using a footrest can reduce strain on the lower back and legs, promoting better circulation. They are commonly used in offices, homes, and even in vehicles. Many ergonomic chairs also include built-in footrests to enhance user comfort and support overall well-being.
