Why Do You Need A Knee Pillow?

Most people may not be using a knee pillow because they do not know what benefits it may add to their sleeping. Basically, you cannot trivialize the importance of a knee pillow.

Correct Posture

This is mostly important for side sleepers who need two pillows; one to support the head and another to separate the legs and support them. When you sleep without a pillow in between your legs, the upper legs stay free and can pull on the spine. This will lead to hip and lower back discomfort.

With a pillow tucked between your legs, the upper leg assumes a neutral position thereby keeping the spine aligned well and reducing back and hip pain.


Conditions such as sciatica, slipped disks, scoliosis and osteoarthritis among others cause discomfort during sleep. If the above conditions affect you or have ever affected you, a knee pillow will enhance circulation of blood and keep you feeling comfortable at night.

These pillows are made of a soft material that ease the pain you may have. The knee pillow is highly recommended during pregnancy as it reduces the pressure on the knee and reduces twisting of the hip joint.

Better than Body Pillows

While you could use a body pillow instead of a knee pillow to separate your legs while you sleep, the former takes a lot of space and may not be ideal when you are sleeping with a partner. Body pillows are bulky and may not fit well between your legs.

​Reduce Sleeping Stress

Another benefit of having knee pillow is that it is easy for you to assume a sleeping position that feels comfortable as it gets all your body parts in agreement. When you reduce the tossing and turning that you may experience the first few minutes you hop on to your bed mattress, you will relax easily and fall asleep fast. With a good night's sleep, you wake up relaxed the following day, have a better outlook and can accomplish much with all that energy.

Considerations When Shopping for a Knee Pillow

A knee pillow should have a perfect comfort-support balance to deliver all the benefits outlined above. With the high number of knee pillow brands, it may be a challenge getting the best knee pillow for you.

There are many pillows made of low quality foam; these will flatten after a few months of use and lose their shape. With no shape, a pillow will be as good as a piece of cloth tucked between legs as it cannot offer the needed support. When shopping for a knee pillow; ensure you:

Preferably, Buy Memory Foam

The advantage of memory foam is that it conforms to your bone structure. It is firm enough to offer support and still soft enough to offer comfort. Bed mattresses also use memory foams for great relaxation.

This material is great in heat retention and will enhance blood circulation. Though heat retention can bring discomfort, most pillows come with a breathable cover for temperature balance. Unlike other materials, memory foam does not get flattened permanently even after a few years of use.

Buy an Ergonomic Shape

There are different shapes of knee pillow including wedge pillow, long knee pillow, hourglass shape knee pillow and hypoallergenic knee pillow among others. You need to choose a pillow that gives you comfort while you sleep. While someone may get comfortable on a wedge pillow, it does not mean you also need a wedge pillow.

A wedge pillow is shaped like a pyramid and is ideal for back sleepers who like keeping their knees slightly elevated.

The long pillow comes in the shape of a body pillow. It is used to cradle knees when you sleep on your side. One leg is placed on top of the pillow and another one under the pillow. This pillow is popular thanks to the fact that it is a good fit for all.

Hourglass knee pillow, like its name suggests, is shaped like an hourglass. This shape allows it to stay in between your knees without slipping at night.

Hypoallergenic knee pillows are thick knee pillows designed to reduce pressure on the hips, shoulders, lower back, knees and neck areas. Some people use regular body pillows folded in half to act as wedge pillows; however, these keep moving at night thereby causing discomfort.

Choose Medium Firmness

The firmness of the pillow will determine the support, comfort and durability of the pillow you choose. A soft pillow may not offer the needed comfort and may flatten within a few months of use. On the other hand, a very firm pillow will cause discomfort on your knees. To this end, you need medium firmness.

A thin pillow may not separate your legs enough while a very thick pillow will raise your leg uncomfortably. A knee pillow should just raise your leg to keep it in line with your hips. For great results, buy a pillow whose density is three pounds or more. Anything less than that will either be too soft or too thin.
