Someone gave me this pillow when she didn't need it anymore. I'm not pregnant, but I have a great deal of pain in my shoulder joints, so not only did I have trouble getting to sleep, but during the night, the pain would wake me up.
I can't say enough good things about this pillow. It's soft and I can easily make it conform to whatever position I'm in, even when I move around in my sleep. It cushions my shoulders and provides support to my neck and head, and it feels like I'm being hugged to sleep.
I haven't been to this site before, since someone handed down the pillow to me. I googled today to see how I should wash the cover (machine washable!). I hadn't though of any of the configurations they show, but I'm definitely going to try one for reading in bed!
I don't know how this would be for pregnancy, but for me and my painful shoulders, it is heaven.
