These Changing Table Pads were a request from a customer who had been using 2 Lap Pads on public changing tables. (Now why didn't I think of that...?) They are the same as the Lap Pads, except longer covering most changing tables either at home or out & about. The front is a soft flannel and the waterproof backing is a soft polymer and polyester. They are 18" x 30" and wash and dry (in the DRYER) so easily time after time. You'll need more than one! (These Pads aren't meant for bedwetting use.)
