These pillows keep their shape well, are VERY big and fluffy, if even a bit on the firm side. I typically have needed several pillows above and all around my head at night to get the right kind of support (some firm, some soft down, some medium, etc...) and these pillows are full enough that I sleep very comfortably (mostly on my side) with just one pillow (very suprising). The down has sortof been able to work is way through the quilted covers that come standard with these pillows. I only notice the feather dust (NEVER any quills) when I change the pillow cases, and I'm pretty sensitive to it, so I don't think it's an issue - I just added another pillow cover, no sweat. These pillows are very good quality, with a high fill level and will last a very long time.
