Placing a pillow between the thighs for pregnant women is an effective way to improve comfort during pregnancy. If you are pregnant and experiencing pain or discomfort, you can use a pillow between your thighs to improve the comfort of the fetus. This pillow helps to improve sleep position and relieve pressure on the spine, hips, and knees by providing the necessary support to these areas. It also reduces the likelihood of swelling in the feet and legs and plays an effective role in improving pelvic alignment, distributing body weight, improving blood flow to the lower limbs, and supporting the fetus inside the uterus.
