Query: Best Maternity Investment Ever!

I never purchased a maternity pillow for my first pregnancy, and I slept horribly the entire time. I am a back sleeper, so sleeping on my side is extremely uncomfortable anyway. I thought I'd take a chance with this pillow. AMAZING! I've been using it for 5 months and love it! It wedges me on my side so I don't roll forward or backward. It gets a little warm in the summer, but it was great in the winter. It also takes up a bit of the bed, but not too bad (we have a Queen-size). I highly recommend this pillow for anyone concerned about sleeping while pregnant. It was the best maternity investment I could have made.
