WOW!  This thing is big and bulky.  I ordered for our new travel trailer hoping it would add some cushion to the hard as concrete mattress.  It is fluffy that is for sure.  I guess I should have taken that name serious.  It is 3" a the very least, soft like a wool/mink blanket.  I ordered a short queen, barley fit in my front load washer and burnt, literally, a hole in it in my front load dryer.  Now I have this huge cover that I can't store for the size of it and can't return because of the burn hole... I also think it would be very very hot to sleep on.
