There are three main designs of pregnancy belts. Some are cheaper than others and the price depends on the complexity of the design as well as the materials the pregnancy belt is made from.
Simple pregnancy belts are made from light, elasticated material that has one layer and closes with a velcro. Sometimes these simple belts include a piece of fabric that covers the bump. Simple pregnancy bands offer very light support and usually are not very effective at alleviating pains.
The second type is a pregnancy belt with extra support, made from slightly sturdier material. These maternity bands have one fastening panel that is tightened underneath the belly with velcro. These types of bands offer a slightly higher amount of support for the abdominal area.
The third and most supportive type is a maternity support belt with extra back support and double layer compression, like the Lola&Lykke Core Relief Pregnancy Support Belt. These types of pregnancy support belts are ultra supportive and help to spread the extra weight of pregnancy to other parts of the body. This brings relief from back pain, from hip separation or pelvic girdle pain (PGP) and pelvic pressure. The double layer design effectively helps lift up the belly and improves the posture, making it very effective in alleviating most types of pregnancy pains.
