The shape you see is a sheet ? No ? Yes! This is typical for blend down cushions, the quantity of feather provided is very little, the quality of feather provided is the low end, 90% feather 10% down, and then the sheet of dacron in the encasement grabs the feather. This nullifies any feather behavior there might have been. **
To re-word that for you, what is called blend down is a marketing device, the typical blend down cushion does not deliver the behavior of down.
