I got these hoping to replace tired down on my couch. They didn't quite work for that, but are so soft and comfy that I am keeping two of them for my bed. Though they look full and keep their shape, they mash down with the weight of my head and are as satisfactory as down. They did not fit the slipcovers I made for them because they are not the right shape for a box cover. Definitely a learning experience for me. They are a tight fit in some of my pillow cases but worth the effort to stuff them in.
