Chilling Home Pregnancy Pillows - U Shaped Maternity Pillow for Pregnant Women with Velvet Removable Cover - 55 inch Pregnancy Pillows for Sleeping - Body Pillows for Adults Full Support - Grey

At first I had a big C shaped one I got from target but I couldn't switch sleeping sides easily, without moving the pillow with me. I ended up getting a U shaped one like this https://a.co/d/095vLvRC and it's the best. Easily can turn side to side inside the pillow without moving it. Sometimes I'll use it upside down so I can use my regular pillow.
