GG, the piggy mat came...it is not heated...just a rubber mat 34 of an inch thick, 33 inches by 48 inches. Hope it works out....the UPS man slipped in and back out again without us hearing him...again. Forgot I had ordered it at first, when dh asked me "What is that" I replied, "Let's open it and see!" So its down under dh's computer on the floor. Funny.
