I’m all for anything that makes you warm, but this cushion might be a touch more cheesy than I can handle.  In order to keep your rear warm you just sit on this flower shaped cushion, in the center of a cushion is the face of a smiling sheep.  Why there’s a sheep in the middle I have no idea.  You can plug it into your USB port and it will begin warming your seat.  You can purchase it for $19.90 from Gadget4all.
