Anyone have an idea for not burning my legs wih the hot lap top?(read details)?

I'm home schooled and I have to be on the pc all day. But the lap top gets really hot at the bottom and it's frustrating when I have to be changing positions so many times. I like to be comfortable so sitting at a table isn't an option. I dont want a hard book cover on my lap either so im currently trying, a mouse pad in between the hot pc and my leg. I can't have a pillow to put in between either because the air won't ventalate the pc. Anyone have a COMFORTABLE idea I can try that doesn't make the pc hotter but doesn't burn my legs?
