How Exactly Does a Knee Pillow Work?

Sleeping on your sides or in a fetal position helps to maintain the quality of sleep and keep you healthy. This position helps to maintain the natural arch of the spine, keeping the body properly aligned.

Apart from that, placing a pillow between the kneesremoves the pressure from the lower back and hips by distributing the weight evenly throughout the body. They also help to minimize the tension in legs and lower back.

A knee pillow also helps you relax the hamstring muscles by enhancing the back and leg relaxation. By keeping the hips and pelvis in right place, the spine will be properly aligned, making you more relaxed.

Knee Pillows have become very popular because of their effective results in reducing pain and support the knees while sleeping. During sleep, the muscles present in our body become sore when pressure is applied on them.

If no support is provided then pelvic area gets rotated leading to a misalignment in the spine. This ultimately leads to discomfort and pain. This can be prevented by placing a pillow between your knees, especially if you sleep on your side. The pillow support ensures the spine is properly aligned and removes off the pressure from the nerves and muscles.

Different Types of Knee Pillows

Though most of the knee pillows are pretty much alike, there are different in sizes, shapes and other reasons. We have mentioned them clearly below…

1. Hourglass Knee pillow

An hourglass is one of the most common and affordable option in knee pillows. Its specially crafted shape prevents your legs from sliding or moving while sleeping. Apart from that, you can also place it under other body parts as well like thighs, back or others based on your needs.

2. Strap on Knee Pillow

This type of pillow contains a strap which can be attached to any one of your legs. This functionality prevents the pillow from moving or slipping in the night. When it comes to durability, the pillow design lasts much longer than hourglass pillow.

Though they look very simple, the strap functionality makes it more expensive than other types of pillows. Some strap on pillows are available at a cheaper rate as well but they are not effective when compared to contoured ones.

If you are a side sleeper then you have to place the knee pillow on the lower leg or lower knee. If you sleep with your legs straight then place the pillow a little higher near groin. The size of the pillows in combination with bedsheet and comforter, restricts your movement while sleeping. Pillows with large straps come in multiple sizes, so they can fit either long or short legs.

3. Long Knee Pillow

Long knee pillows provide improved support to lower body and also prevent you from turning over or moving around while sleeping. They are perfect for people who like to cradle entire body while sleeping.

4. Wedge Knee Pillow

This type of pillow has a triangle shape which brings the lower and upper parts of the legs in a triangle position. They are very helpful in reducing the lower back pain.Other than that, it also helps to reduce swelling in feet, tired muscles and varicose veins. As it slightly elevates the knees, they are perfect for people who prefer sleeping on their sides.

Buying Guide: Knee Pillow for Side Sleepers

With all those different features, materials and others, it is not easy to select one. So, we have gathered all the information required that will help you take the decision.

1. Firmness

When it comes to knee pillow, it shouldn’t be either too soft or too firm. The right amount of firmness will keep the knees comfortable enough to relieve the pain. For most of the people, medium fitness is perfect as it keeps the knees apart which is the main reason for using a knee pillow.

2. Material

Most of the manufacturer’s use materials like water gel, memory foam and others. Among them memory foam is the pricier and firm one. As they are hypoallergenic, comfortable, and softness most of the people prefer it. However, you have to select the material based up on your sleeping style and condition. Because not everyone require a firmer cushion. Apart from that, you should also consider the durability and support of the material. Check out the quality of the pillow cover fabric as well. It should not irritate your skin and should be easily maintained.

3. Size and Dimension

For pillows that elevate our body, angle and height play an important role in determining the comfortability. As per many specialists, pillows should raise the legs or back at certain level that is higher than heart’s level. However, if the height is too high then you can strain the hips and lowerback. Check out the width of the pillow as well. Make sure both of legs can rest on it comfortably. Too wide knee pillows can strain your pelvis and too thin knee pillows don’t provide adequate space to realign the spine.

4. Thickness

A thin pillow will not be able to maintain proper distance between the legs. Make sure the pillow has at least 4 – 6 inches depth for good comfort and perfect spinal alignment. If you are overweight then go with a pillow that has maximum thickness.

5. Durability

Knee pillows are a health investment. So you have to be very careful about its durability, especially as some of them are quite expensive. Make sure the manufacturer provides enough guarantee that it won’t flatten, clump or get damaged.

6. User’s Body Weight

Thickness of the pillow should be determined as per your body weight. For example, if you are an overweight user then a thicker pillow is the ideal options. If you are an average or skinny person then softer ones are the best choice. Soft materials like memory foam usually tend to dimple as per the weight applied. So, a heavier person needs a firm or high density ones than lighter person.

Size of the person also determines the size of the knee pillow to purchase. For people who have short legs, a knee pillow with high elevate can be uncomfortable. For people with long legs, a sharp angle elevated pillow can be uncomfortable. For people who have slim pelvis, it is recommended to purchase a thinner pillow. For people with wider pelvis should consider wide knee pillow.

7. Purpose

Every product is designed to cater certain problem. Some may provide improved blood circulation while others provide back pain relief. So, you have to choose the knee pillow based on your requirement.

8. Flexibility

If you like to fold the pillow between the knees then choose the one which has good flexibility. Side sleepers like to tuck or twist the pillow so it is better to choose gel based or shredded memory foam knee pillow.

9. Cost

If you have a tight budget, make sure to get most of the amount you can cater. Most people think that expensive products have higher quality. But that’s not true always. So, check out the quality and reviews before purchasing the product. Some of the low-quality knee pillows can provide results initially but they worsen the condition overtime. So, purchase a durable product that serves you long term.

10. Density

Usually, the average density of the high quality knee pillow is between 3 – 4 pounds. If the density is too low then it will not support the weight of your body, leading to additional discomfort. So, make sure to check the density of the pillow before purchasing as different materials have different densities.

11. Support

During sleep, a knee pillow should securely support the knees, legs and hip in a most natural position. If not then it can lead to additional discomfort. So, make sure the pillow doesn’t slip off or slide away during sleep.

12. Comfort

Knee pillows for side sleepers should stay together all night without disturbing the sleep. This is more important for people who deal with…

• Spine misalignment
• Hip bursitis
• Pregnancy
• Back pain
• Knee arthritis
• Recent surgery
• Pregnancy
• Sciatica

13. Cooling Action

As you will be placing the knee pillow all night, it should not generate heat or sweat, which can disturb your sleep. Make sure the knee pillow you choose has a cooling property.

What is the Appropriate Way to Place a Knee Pillow?

If you want to achieve effective results then it is very important to place the knee pillow properly. Below is the appropriate way…

1. For Side Sleeper:In this position, you have to place the pillow between the thighs or knees. This pillow placement ensures proper position while sleeping. This is perfect for people who underwent a leg surgery. This also prevents you from rolling over.
2. For back sleepers:In this position, you have to place the pillow under the knees in such a way that knees stay up and remove the pressure off the spine. They can also be placed under other parts of the body. For example, you can place it under the arms when you are lying back.

Advantages of Knee Pillows for Side Sleepers

Who Should Purchase a Knee Pillow?

Purchasing a knee pillow is one of the great investments anyone can make. Below we have explained reasons…

1. Back Pain

People dealing with sciatica often suffer with insomnia and other issues. If you align the legs properly using a knee pillow, it helps to reduce the swelling caused by sciatica nerve. Usually, sleeping on the sides increases the pressure on the sciatica nerves. By using a knee pillow, the upper leg gets elevated – which helps to reduce the pain and inflammation.

2. Hip Pain

A knee pillow helps to prevent the hips from moving or rotating while sleeping. This positioning also helps in preventing the body from angling over – which can worsen the condition.

3. Side Sleepers

People who sleep to their sides often experience walking up in the middle of night and improper rest. This is experienced because the bones in our knees bump into each other while sleeping. Placing a knee pillow can help preventing this situation and also improve sleeping quality.

4. Back Sleepers

Do you prefer sleeping on your back? You can still get the benefits of a knee pillow. It helps in relaxing the legs and reducing the tension in lumbar area. Apart from that, it also helps in keeping the spine aligned and reducing the pressure on tailbone.

5. Expectant Women

Women who are pregnant have restricted sleeping positions. Placing a knee pillow helps to ease the pain, discomfort and this position has reduces the times the baby kicks. Placing a pillow keeps the body aligned, relaxed and promote healthy circulation.

6. Poor blood circulation

Poor circulation often leads to swollen legs, varicose veins, etcetera and muscle stretching. Sleeping position also have an important role in blood circulation due to gravity. Elevation in legs help to reduce the tingling and spams associated with poor circulation. Elevation also helps in improving healthy blood flow from heart to other body parts.

7. Surgery Patients

Discomfort and pain are common things experienced after a surgery. To get relief from the same, it is very important to align the spine, knees and hips. Placing a pillow between knees helps to align the bone structure, providing pain relief and comfort.

8. Spine Misalignment

If you are dealing with spine misalignment then a knee pillow can be very helpful as it helps to elevate the body and promote good sleeping position.

9. Painless Sleeping

Experts who have been studying sleep confirmed that most of the people prefer sleeping on their sides. Though it provides very good support to the natural arch of the spine, not everyone can experience pain free in that position. And a knee pillow will be helpful in the same. It works in two ways – provides relief from hip pressure and supports the spine.

Placing a knee pillow supports the knees, provides relief to sciatica nerve and aligns the spine in a better way. Many users have confirmed that using the knee pillow has improved their sleep a lot.

10. Improves Sleep Quality

Usually people dealing with insomnia take medical sleeping aids which eventually become ineffective. And sometime, people get addictive too much to them. But knee pillow is a natural, drug-free solution to align your spine and prevent insomnia.

Frequently Asked Questions

1. Foam or Memory Foam – Which one to choose?

In most of the pillows, memory foam and polyurethane foam are common material used. Both these types are available at the same cost. As per our research and testing, memory foam is much more supportive than standard foam. It perfectly contours to the shape of your legs and reduces the shifting of legs while sleeping. As memory foam fits exactly to the body so it may generate a little bit heat than normal foam.

2. Are Knee Pillow Covers Durable Enough?

For some strange reasons, most of the knee pillow covers suck because most of the fabrics used are white in colour. Overtime due to sweat, oils and washing, the white covers turn in yellow. Most of the pillows have zippered removable covers, they can get wear off easily.

We recommend using a standard pillow case over the knee pillow, as it will keep the pillow hygienic and simple. But as some of the knee pillows have odd shapes like hourglass, normal cover is not going to be a perfect fit. But you can just fold the excess underneath the pillow and place it between the knees.

3. Should We Remove the Tags of Knee Pillow?

Usually, knee pillows come with tags and some of them are frustratingly long. And worst part of these tags is that they sometimes irritate while sleeping. If you want to remove these tags then you have to be very careful, because the tag will be sewn directly into the seam. If it is removed incorrectly then it can leave a tear or hole. You can also cut the tag as closely as possible using a scissors.

If the tag is not causing any trouble then leaving it is recommended. Usually hourglass knee pillows will not have any tags. But strap on knee pillows will have the tags.

4. Does a Knee Pillow Give Away Foul Odor?

When the package is opened, memory foam pillows give away a foul odor. If the smell is worrying you then leave it out in air for a couple of days. This will eliminate the smell coming out from the knee pillow.

5. For whom is a knee pillow most recommended?

• Back Sleepers: It helps in reducing the tension and relieving the pain in the lumbar area.
• Side Sleepers: using a knee pillow raises the upper legs and helps to maintain the spine alignment properly.
• Pregnant women: sleeping to their sides is the most beneficial sleeping posture during pregnancy. It helps in reducing the pressure in hip joint and back.
