Users say this U-shaped pregnancy pillow helps alleviate back pain, even calling it a chiropractic pregnancy pillow. Wrote one pregnant mama, who heard about the maternity pillow from her chiropractor, “It’s helped immensely with round ligament and pelvic pain. Plus it allows me to easily flip from one side to the other all night without having to readjust my pillows.”
Pregnancy fashions took a dramatic turn in the 1990s with the introduction of tight-fitted maternity wear intended to emphasize rather than hide a pregnant woman's baby bump. Not coincidentally, this shift occurred during a time of major changes for women in America. In 1993, the Family and Medical Leave Act was passed by President Bill Clinton. This act protected women's jobs during pregnancy, giving women more freedom to show off their pregnancies. 
It is recommended to sleep on your left side, as it increases the amount of blood flow and nutrients to the placenta. You also can better help relieve back pain by sleeping on your side, a common complaint of many pregnant women. Later in pregnancy, many women experience heartburn, making any position that has your head more leveled with the rest of your body uncomfortable. This is when raising your upper body slightly can help, and sleeping on your back, with your upper body elevated may provide the relief you need.

As with any pillow, a natural fiber and low thread count are what will help you keep good breathability and air flow through the night. Most covers are a cotton or cotton blend, is washable, and will easily pull onto the pillow even if it’s an odd shape. Occasionally the full body pillow covers can present a challenge when taking it off and putting on, and how they are constructed can help determine the effort required. Long zippers are usually the most helpful as they expose more of the pillow itself. But other types may only have a folded over flap that requires you to fold the cover back on the pillow.
