DescriptionMade with high-density, performance-grade rubber foam, these standing mats provide thick support and relief from fatigue caused by long periods of standing on various floor surfaces. The built-in vibrating massager gives a deep, relaxing foot massage with just the touch of your foot, and helps reduce pain from prolonged standing while increasing leg and foot circulation. It also features a non-slip surface that is contoured and textured for added safety and stability. The unit is powered by the included micro-USB cable that can be plugged into any computer or USB block. The mat is the perfect size for any space, and is ideal for use in kitchens, offices, with standing desks, at home or any other work area that requires long periods of standing or sitting.
