This pillow works much better for me than the u-shaped pillow I had before. The firmness, strap, and shape hold it in place much better and prevent my baby from rolling outwards or inwards. It has helped my posture much more. The pocket is handy too. It doesn't quite do all it claims for me- I find it still doesn't hold its position high enough under my breasts without also propping it up with a pillow underneath, but perhaps this is due to my torso length or the weight of my baby. But it is much better than the alternatives.
