Anti-fatigue mats:
Think of it as a seat cushion for your feet.
Anti fatigue mats are a great solution for easing the transition to a standing desk. Available in several colors and textures, an anti-fatigue mat will integrate into your workstations seamlessly. If you are using one of these standing mats with an adjustable-height desk, simply push the mat out of the way under your desk when you are sitting, and pull it back out when you are ready to stand. Your legs and feet will thank you.
