No fluff to fill
Style: Medium/Firm, Size: Queen
Arrives vacuum packed; not a problem with that; however, a week after opening the pillows are still flat. I thought they might still work for my pillow shams - not what they were bought for, but they didn’t fill out the shams either. Sad as I really like Serra brand normally.

Keep their form for a bit
Style: Medium/Firm, Size: Queen
These pillows are fairly good quality, and keep their form better than what you might pick up at the end of the row at a big box store. After about a month of regular use, they've collapsed visibly from what they were on the first day, but still provide support. They are shipped flat in a container and take some time to plump up, but I didn't notice any strong odor on opening. Like most foam pillows, I expect a trip through an electric clothes dryer will probably fluff the pillows up again. I don't know what makes these "down alternative" as oppose to a regular foam-filled pillow, and there is a sharp distinction from my down pillow. Most notably, the down pillow provides much more support. There would be no mistaking one of these for a down pillow.
