While this is advertised as a "coverlet" the picture on the website implied something of volume.  If you look at the sheet/mattress line and draw it across to the bottom of the bed there is a distinct thickness implied to the product.
Having said that, it functions very well, is attractive, and warm.  As some others have said it is not an overly generous size.  I probably should have ordered the King size for my Queen bed.  Still, 4 stars.
