St. James Home 5 Inch Feather Bed with Cotton Cover, Full Size

It did fluff up to 5 inches... of air. It's definitely not filled with 5 inches of feathers. Not counting the air it's about 3 inches and it gets very flat where you lay after a while so it ends up MAYBE an inch. I have it fluffed it a few times a day. There's no indication of which side is supposed to be top and which is supposed to be bottom. That said, before it gets flat, which is usually by time I wake up, it's very comfortable and soft. This might be okay for an average person and it probably wouldn't deflate for someone very light. However, being mostly bedridden, it can be a bit of a hassle. I'm torn between the comfort that it provides when it's not flat and the hardness and hassle it is when it is flat. I probably would have returned it if it wasn't a Cal King and I could have gotten it back in the package as soon as I saw it was mostly air. For now though it'll do until I make my own. For the record, I'm 160 pounds so not very heavy.
