Just soak the mat in cool tap water (in a sink or tub), allowing the MiraCool crystals to absorb water and fill the mat's channels. Shake off excess. When hydrated, the pad provides a cool soft resting spot on floor, patio or other shady place. To maintain mat in excellent condition, hang in open air to allow air to dry when not in use. 18 x 14 Inches
