I know pillows are very personal it's like trying to find the perfect pair of jeans without trying them on! I prefer soft pillows that are not overly filled. I also do not like Feather pillows. I read the reviews that said "it was flat." PERFECT. However, I do not feel this pillow is flat. I have only been using it for a month now however it is holding it's softness and relative fullness. I really like this pillow. I did not stack them as others have done. I am only using one. Hope this helps someone who wants a soft pillow that is slim in it's fill.
