A footrest is a supportive device designed to elevate and support the feet while sitting. It helps improve posture by allowing the legs to rest comfortably, reducing strain on the lower back and promoting better circulation. Footrests can be adjustable or fixed in height and are commonly used in offices, homes, and other seating areas. Many footrests are made from materials like plastic, wood, or foam, and some feature non-slip surfaces for added safety. They can also come with ergonomic designs to enhance comfort. Using a footrest can be beneficial for individuals who spend long hours sitting, such as those using office chairs or working at desks.
