What is a knee pillow?

people who usually sleep on their side are familiar with discomfort, which may be the result of resting one knee on the other while sleeping. At that time it is not only unpleasant, but it can lead to other pain in the hip and lower back due to unnatural knee location. The knee pillow is an orthopedic pillow designed to relieve pain in the back, hip and knees. This is achieved by placing the pillow between the knees at night, maintaining it separately, thus reducing the hip. The knee pillow with an hourglass shape tends to remain in place overnight quite well, because it turns the general shape of the knee and legs. Since the rectangular cushion of the knee does not have this advantage, there are some models that include a textile strap that ovrates around one leg to keep the pillow in place. The strap connects to the pillow cover, which is washing in the washing machine.

Another interestingThe variability of the pillow to the knees is one that has an hourglass or butterfly on both sides, but can open in the middle. This type has curtains on it to open the pillow and be placed on the bed. After openness, this type of knee pillow can be used to support head and neck or for altitude of legs. In this way, this kind of knee pillow can use a person who sleeps on his back, as well as someone sleeping on his side.

One type of specialized knee pillow is a type of memory foam ™. Memory Foam ™ is a material made of polyurethane with other chemicals that increase its density and thickness. It has a feature that it is able to adapt precisely to the outlines of the body because of its amorphous nature. This effect is visible, for example, when you push your hand into the foam and then remove it. For a short time, the foam "remembers" his hand and keeps the impression.

This type of material is suitable for use in knee pillows. Its ability to contourT exactly on the body of a person keeps a pillow in place overnight and also provides the right amount of support wherever it is needed. Memory Foam ™ was originally developed by the National Aeronautics and Space (NASA) United States. The Space program has never actually been used, but since then it has found use in many orthopedic and medical applications.
