A rubber pin mat is a mat made of rubber that has a series of small, raised pins on its surface. These pins are designed to provide a massage-like effect when you walk on the mat or place your feet on it. Rubber pin mats are often used in areas where people stand for long periods of time, such as in a kitchen or at a workstation, as the massage-like effect can help to improve circulation and reduce fatigue. They may also be used in physical therapy settings to help stimulate blood flow and improve balance. Rubber pin mats can be placed on the floor or used as a footrest. These are available in varied sizes.
