What’s inside the Cooling Seat Pad? Is the gel toxic, and will it leak? The Cooling Seat Pad uses an eco-friendly, non-toxic gel that meets RoHS safety standards. The gel is engineered to stay in a jelly-like state and is double-sealed within the pad, so it won’t leak under normal use. Be sure to keep sharp objects away from the pad to avoid puncturing the outer layers. Back to FAQs List
