Memory foam pillows are made of viscoelastic polyurethane foam which softens to the weight and body heat of a person allowing it to 'mold' to a warm body while supporting the pressure points of the body, and then quickly returns to its original shape after the weight is removed. Specific shaped memory foam pillows offer distinct support for the head/neck as well as cylindrical shapes for the lumbar region, and contoured shapes for knees and thighs.
What is a Memory Foam Pillow?
A memory foam pillow can refer to various types of pillows made of visco elastic foam. Since it is very soft when weight is applied to it, people are often surprised when memory foam is felt for the first time. Memory foam bed pillows are made in several different shapes, and the classic shape is contoured so the lip of the pillow sits securely under the neck. If the pillow lip is the right height, this may help align posture. There are standard pillows made much like the shape of an average filled pillow, and some pillows are made for those with smaller frames by having a foam insert that can be removed to lower the pillow’s height. Those who sleep on their stomachs may prefer a more standard sized pillow because the contouring can get in the way if a person is face down on it.
There are memory foam pillows made for other areas of the body, too. These can include lumbar support pillows which are often cylindrical in shape and could be used under the lower back when lying down. To provide extra support, they can also be used between the back of a chair and the user’s lower back. There are types that may be useful with office chairs that are larger, and can be attached to the back of the chair. Another helpful memory foam pillow is called a contoured leg and knee pillow, which is usually inserted between the knees and thighs. Pregnant women tend to be fans of this style because it can make sleeping more comfortable, and reduce some backache or other aches and pains associated with pregnancy.
How does Memory Foam Work?
Basically, memory foam is an insulating material that responds to temperature changes. The foam realigns to provide a cushion as it comes into contact with something that is warmer. It does this by softening at the points where the body increases the foam’s temperature. It molds itself to the contours of the human body when used in a mattress. This provides excellent support at pressure points along the legs, spine, hips and arms, making it possible to avoid some of the stresses on the body that occur during sleep on any other type of surface. The foam automatically realigns to maintain the cushion effect when shifting positions. There is less of a chance of waking in order to find a more comfortable position when the pressure is evenly distributed across the whole body. This may result in deeper REM sleep.
What is a Knee Pillow?
Those who normally sleep on their side may feel the discomfort that can result from resting one knee on the other while sleeping. Because of the unnatural positioning of the knees, it is not only uncomfortable, but can lead to further pain in the hips and lower back. The knee pillow is designed to ease the pain in the knee, hip, and back areas. This is accomplished by placing the pillow between the knees at night to keep them separated, therefore reducing strain on the hipbones. Most knee pillows have an hourglass shape, while others have a rectangular form. Because of how it contours to the general shape of the knees and legs, an hourglass shaped knee pillow tends to stay in place fairly well overnight. Since a rectangular knee pillow does not have this advantage, some are available with a fabric strap. This strap wraps around one leg to keep the pillow in place, and attaches to a pillow cover.
Another design variation of the knee pillow is one that has a butterfly or hourglass shape on both sides, but can be opened up in the middle. This type has hinges on it so it can open up and be placed flat on a bed. When opened up, this design can be used for neck and head support, or for leg elevation. That way it can be used by those who sleep on their back, as well as by those who sleep on their side.
How do I Choose the Best Neck Pillow?
Neck pillows are helpful devices to support the neck and minimize the chances of having some type of neck pain. Since there are many types of neck pillows available, choose one that suits specific needs. If there are any particular health issues, be sure to keep those in mind. There are different levels of support in neck pillows. Some individuals require a pillow that is firm, while others will want one that is more pliable to conform to the contours of the neck. Talking with a doctor to determine what type of support is best may be necessary.
Another important consideration is the intended function of the neck pillow. Perhaps one is needed to be a good travel pillow that will not take up much room, but will offer the support that is needed. A memory foam neck pillow or an inflatable pillow may be a good choice. Both types easily fit into a carry-on bag, and can be ready for use in a few minutes after settling in a seat. For sleeping at night, bed pillows which are designed to provide neck support come in many types and styles. One option is a bed pillow that is designed to provide cervical support. For those who have a problem with numbness and tingling, a traction neck pillow will help to keep the neck aligned while sleeping. It can also help a user’s rest to be more refreshing.
A bath pillow is another form of neck pillow that may be helpful. A neck pillow of this type often uses memory foam to adjust to the contours of the neck and is sealed with a waterproof shell. The pillow offers comfortable support while an individual is reclining in the tub. This can come in handy if various types of disc problems are present, as this type of pillow won’t restrict the range of motion.
