I'm a back sleeper too!! I'm borrowing these squishy pillows from my sister that are filled with beans lol, and I have lots of feather pillows, I also bought a chair pillow - you know one of those pillows with the arms? I'm thinking I might end up sitting up and sleeping. I did a lot of research about pillows and stuff I think you just need to try to get creative with what you think will work best for you. I also considered one of those neck travel pillows but wasn't sure so didn't buy it.
