“Convenient, portable, rejuvenating” – just some of the many testimonials for this anti-fatigue product. Kneeling Comfort mats are designed to help relieve knee trauma and back stress for workers that kneel for extended periods. There are two versions: a Foam only version and a version that has a Nitrile Rubber base (designed for harsher working conditions). Both mats are made of a closed cell cushion that will not absorb liquids. The versatile built-in handle makes storage and transporting Kneeling Comfort easy.
