I am using this pillow now and about to enter my second trimester. I find the pillow to be comfortable and useful in training myself to sleep on my side. I actually find the pillow most comfortable upside down (with the connected piece at my feet). This allows me to use the side bolsters, elevate my feet, AND use my own pillow.
Positive
