  • Check out the pillow shape

The knee pillows come in three different shapes: the hourglass, wedge, and roll body pillows.

– The hourglass knee pillow

The hourglass knee pillow is relatively standard and the most affordable among the three styles. These shapes of knee pillows are comfortable and easy to insert in between the knees since they are crafted to contour to the knee cap. In return, this helps to hold both legs in the same position for a comfortable sleeping position. They have padding to provide support and cushioning. The hourglass pillows are the best for side sleepers

– The wedge pillow

The wedge pillows are crafted in a triangular model. These pillows are recommendable for back sleepers since they are meant to be placed beneath the knees. Note that you can also use the pad if you are a side sleeper.

– The roll body shape

These knee pillows are crafted to accommodate different people, especially of large body sizes. The body pillows are quite large such one can tuck the body pillows between the legs to relieve pressure on the knee. The roll body knee pillows work by reducing the stress between the knees and both legs.

  • Consider the sleeping position.

Your sleeping position will influence your choice of knee pillow. The choice of the knee pillow is determined by how you position your legs when sleeping. For example, for a side sleeper, you need a knee pillow to place between both legs considering one leg lies on top of the other one. A knee pillow helps to reduce pressure on the lower leg.

You need a pillow that you can place below the legs to alleviate them to relieve tension and pressure for back sleep.

For stomach sleepers, you need a knee pillow that you can place on both knees on the front side to align them and keep them in an elevated form. This is quite critical for people who have knee injury. Note that a bed pillow can also work as a knee pillow for stomach sleepers as long it has the right padding for support.


How to Choose a Knee Pillow for Different Sleepers?

Side Sleepers

  • The size

The pillow’s size will determine your comfort and the area to support when sleeping on the side. So, make sure to choose a pillow that has a reasonable size to support both legs when sleeping. The pillow you choose should conveniently support the upper leg, so it does not touch the lower one when sleeping on the side. Still, it should not be too large to distract you when turning.

  • Choose a pillow with Velcro

Velcro is a crucial piece to consider when choosing a knee pillow for side sleeping for securing it to the leg. A Velcro firmly holds the pad on the leg such that it cannot move when you turn to the other side. But, make sure to choose a pillow that has an adjustable Velcro for comfortable holding to the body.

Back Pain Sleepers

  • The texture

The knee pillow you place in between the legs supports the lower back that also affects the spine. Therefore, choose a knee pillow that is firm to ensure the spine is aligned in the right position, while providing the support that relieves pressure. A firm pillow prevents the body from twisting when you sleep since it aligns the spine correctly.

Why? If your upper leg keeps moving and turning, it ends up pulling the spine, which aggravates more pain. Therefore, keeping the leg in the same position prevents the pulling.

  • Choose a pillow with high padding

Although most knee pillows are crafted to conform to the knee shape, the model you choose should have enough padding. A firm and padded knee pillow elevate the legs to the same angle with the back, which, in return, helps to reduce pressure related to pain. Also, choose the comfortable padding, .such as memory foam padding.

Hip Pain Sleepers

  • Choose a wedge pillow

The wedge pillows are meant to be placed under the hip area to elevate it in a high position to relieve pain. The pad’s elevation model shifts the pressure from the injured part by evenly distributing it to the entire leg for comfort and reduced pain.

  • Choose a pillow with vents

You comfort when sleeping should be of paramount since you need to avoid as much as possible moving the legs. So, when choosing the knee pillow, make sure it has breathable material to prevent heat accumulation around the injured hip. A pad made with memory form with gel filling or charcoal infusion may work.

  • The size

The knee pillow you choose should cover the entire leg when supporting it. So, make sure to choose a pillow that is large to provide the right support needed.

Stomach Sleepers

  • Choose a firm and thick pillow

For stomach sleepers, the right knee pillow should elevate the legs to create an uneven angle with the body. So, choose a super firm and thick pillow to create this illustration when you sleep on the pillow.
