Maternity pillow is a kind of special pillow for pregnant women, the main role is to help pregnant women in a special period to protect the waist, abdomen and legs. Maternity pillow helps to reduce the pressure of the enlarged abdomen, relieve back pain, and help pregnant women to maintain balance. Generally 24 weeks of pregnancy to start using.

With the increase in gestational age, the size of the fetus becomes larger, pregnant women's abdomen gradually bulging, it will be difficult to find a suitable position when sleeping. Many doctors recommend that pregnant women sleep on their left side. This is because the liver is on the right side of the abdomen, and lying on the left side keeps the uterus away from the liver, but also because the uterus is rotated to the right at this time. Many pregnant women sleep better in the first trimester because they feel tired from trying to nurture and protect the fetus.

It is recommended that pregnant women should sleep on their left side also because the liver is on the right side of the abdomen and lying on the left side moves the uterus away from the liver. Alternating between the right and left side relieves pressure on the back. During the 7th to 9th month of pregnancy, it is difficult for pregnant women to sleep on their backs. This is because the weight of the fetus presses on the large veins of the pregnant woman, stopping the flow of blood from the legs and feet to the heart and waking her up from her sleep. Your doctor will advise you to keep sleeping on your side with the help of a pillow. Some pregnant women find it more comfortable to place a pillow underneath their abdomen or sandwiched between their legs. Putting a stacked pillow or a folded quilt/blanket behind your back will also reduce the pressure on your abdomen.
