The slope on the pillow is a little steep and makes supporting my belly uncomfortable. I can't get it to position comfortably - too far and the slope is too shallow, too close and it's too steep. It also makes me feel like I'm missing back support (so I don't roll off the pillow).
It is more comfortable for use between my legs or under a leg.
Seems to be of good quality. I like the cover, but it'd be nice if they had more colors.
