before i got this pillow i was tossing and turning at night. this was at about 24 weeks. the first night i tried sleeping with the curved end under my legs and my head on my regular pillow. it was a nice. the second night i tried this pillow with the curved part behind my head. SO much better. i have been sleeping sounding since. totally worth the extra $ as i am allergic to dust, dust mites and anything i can breathe in. also, the cover was easy to slip on.
