Pregnancy pillow, and I'm a guy saying this.
When my wife was pregnant, we bought her one and she slept like a rock most nights. I would use it when she couldn't stand it at times. That was over 3 years ago. I ordered another one recently(just because I wanted one) and just got it a few days ago. No lie, for someone like me with neck, back and shoulder discomfort, who has been sleeping flat on his back with a cervical pillow for the better part of 2 years now, this has brought me nothing but sweet dreams the past few days...........and with virtually no pain upon waking.
It's not to knock the cervical or specialty pillows any, but I'm just tired of fighting the good fight against nighttime discomfort, and remembered some of the best sleep was when I had a body pillow. I got good use out of the cervical pillow, but I'm tired of sleeping on my back. I even went so far as to sleep on my "painful" shoulder with no issues. I haven't felt this good for months.
