The U-shape is one of the most popular styles for a pregnancy pillow because it provides mirror coverage and a whole lot of it. It doesnāt just support your growing baby bump, but also other areas of your body that may be feeling uncomfortable, such as your back, sides, knees, calves, hips and feet (which may be swelling!). Although this pillow is full coverage, itās super lightweight ā weighing in at just 3 pounds, so you donāt have to worry about any strain when you lift it on and off your bed. Like many others, itās comfy, velvet material is machine washable (both the inner and outer cover) ā and the polyester fill is easy to contort to a position thatās to your liking.
