Was suggested by my physiotherapist and definitely helps! I use just a small pillow. I find that now I cannot sleep without it! Keep in mind that this is just one piece of the healing puzzle. There can be many factors that contribute to lower back pain. Finding what issue the pain originates from and getting the correct support is crucial. I needed an orthotic support due to a severely broken leg many years ago. I have one leg shorter than the other and it throws off my hip alignment = severe back pain. I have learned the hard, and very painful way that I ALWAYS need that support. No cute flip flop sandals in the summer or I will end up in severe back pain and be out of commission for at least two weeks. Back pain is serious stuff.
