The product is just as advertised, nice firm foam in the wedge shape. It is comfortable to use either on top of the bottom sheet, or underneath it. It has not seemed to make a difference yet in my breathing since my sinuses still get just as clogged up as before. I have to believe it makes a difference in my GERD, since it eliminates the chance of reflux while I sleep. Overall very satisfied with this product.
