That said, there are a couple of flaws to the design of this knee pillow that prevent it from getting a perfect score. It doesn’t feature a strap, for example, so if you’re a restless sleeper who tends to toss and turn, you might wake up and find that the pillow has fallen out of place. The size of the pillow might also be just a little small for some people.

Buying Guide

Now we come to the knee pillow buying guide. Buying and using a knee pillow really can be a life-changing experience. A lot of people struggle to get to sleep due to pregnancy, sciatica, and various other aches and pains, and knee pillows can help in a big way, but it’s vital to choose the right one. When shopping for knee pillows, be sure to consider the following features and factors to make the smartest decision.

Benefits of having a comfy knee pillow

There are plenty of different benefits to be enjoyed from using a knee pillow:

  • Pain Relief – One of the main reasons people invest in knee pillows is because they’re suffering from pain or discomfort while sleeping or just in general daily life. By offering support to the knees and spine, the pillow is able to alleviate this pain.
  • Better Sleep – Naturally, if you’re feeling more comfortable, free of aches and pains, you’ll have a much better chance of drifting off into a peaceful sleep each night. Knee pillows can help to provide better quality sleep and soothing rest at any time of day or night.
  • Alignment – We all have our favorite positions for sleeping. Many people like to sleep on their side, but this can put a lot of pressure on the spine and knees, causing pain and discomfort in later life. A knee pillow helps to keep the spine properly aligned.
  • Circulation – Whether you sleep on your side or back, your circulatory system can suffer during the night. By elevating the legs and providing support for side sleepers, knee pillows can improve blood flow.

Things to consider when choosing the best knee pillow for your needs

5 Best Knee Pillows — Align Your Body and Sleep Better!There are a lot of different factors to think about when choosing the right knee pillow. You have to think about your own sleeping style, for example, with some knee pillows being better-suited for side sleepers, back sleepers, or restless sleepers. You also have to consider the shape, the size, and the materials being used.

Pillow shape

The shape of the pillow is perhaps the most important factor to think about when choosing your next knee pillow. As mentioned above, the best knee pillows traditionally come in one of two shapes: hourglass (contoured) or half-moon. The hourglass shape, such as can be seen in the Calming Comfort Cooling pillow, is best suited for side sleepers, as it fits snugly between the legs when the user is lying on their side. The half-moon shape, meanwhile, is good for back sleepers and other purposes, being placed easily under the knees, behind the lower back, under the head, and more. It can also be placed between the knees like an hourglass pillow.

Overall dimensions

The size of your knee pillow is also going to be an important thing to think about, and the key thing here is to choose a pillow adapted for your own body. Larger pillows will better suit larger people, while smaller pillows are a better option for those who are slim or short.

Pillow filling materials

This is the real core of your knee pillow. The materials used to fill up the pillow will really determine how firm it is and how effective it will be in use. Many top-quality knee pillows contain memory foam, which is also used in mattresses.

Memory foam is able to adapt to the shape of your body over time to provide total support just for you, while regular foam doesn’t have the same functionality.
Poor quality knee pillows will feature materials that weaken and compress over time, so this is a very important factor to think about. You can also find knee pillows with additional materials like cooling gel to provide extra comfort.

Cover fabric

The material used on the exterior of your knee pillow is important too, especially if you’re going to be placing the pillow against your skin often. The material needs to be soft and smooth to provide comfort, but some materials can generate a lot of heat and can also get dirty or develop odors quite quickly, so choosing a knee pillow with a washable and removable cover is often wise.

What kind of sleeper are you?

It’s important to choose a knee pillow that doesn’t just suit your body, but also your sleeping style. We all have our own preferred positions for sleeping, while some of us can be more restless than others. Side sleepers tend to favor contoured/hourglass pillows, while back sleepers or those who sleep in various positions may be better off with a half-moon knee pillow. If you do move around a lot in your sleep, getting a pillow with a strap is a smart thing to do.

What else will you be using it for?

5 Best Knee Pillows — Align Your Body and Sleep Better!Knee pillows don’t only have to be used while sleeping. They can often have a lot of uses and purposes, just like other kinds of pillows, and can be used to provide comfort and support to various parts of the body throughout the day. Do you often find yourself reaching for a pillow while sitting down to read or watch TV? Do you often lie down and need a little extra support under your neck or head? In these cases, knee pillows can offer the support and comfort you need, and half-moon or bolster pillows, such as the AnboCare pillow or the 5 Stars United model, will generally be better-suited to multiple uses than hourglass knee pillows.

How to care for a knee pillow

In order to ensure that your knee pillow keeps its firmness and quality over a long period of time, it’s important to look after it properly.

Whenever the pillow is not in use, it should be allowed to keep its shape and structure, so that means you don’t want to squash it down into a box or put heavy things on top of it.
It’s also a smart idea to invest in a knee pillow with a removable cover, like the ComfiLife Orthopedic Knee Pillow for Sciatica Relief, as these kinds of pillows are a lot easier to clean and keep fresh.

FAQ

It is perfectly possible to sleep on a knee pillow. This isn’t the primary purpose of a knee pillow, but as we mentioned above, knee pillows are multi-purpose items and can be used and enjoyed in a lot of different ways. The best thing to do is simply give it a try and see how it feels. The unique shape and style of a knee pillow might help you to enjoy a better night’s sleep when used in this way. However, we do not recommend buying a knee pillow with the express purpose of sleeping on it unless you’re sure that it can be of help to you.

The key here is to ensure that whenever you’re not using your knee pillow, you need to give it space to retain its shape. These pillows can get put under a lot of pressure during the night, so the daytime is a good moment to let them stretch back out. Don’t place heavy objects or unnecessary pressure on top of them. It’s also wise to invest in a quality knee pillow that will be much more efficient at maintaining its firmness over time. Cheaper alternatives will lose their strength and structure a lot more easily.

The answer to this question really depends on the user and will vary from one individual to the next. Those suffering from sciatica and other pains will generally want firmer knee pillows, while those who are just looking to protect their legs and back while sleeping or looking for a little extra comfort might be happy enough with a soft one. In general, firmness is recommended. Softer pillows tend to be lower quality and will flatten more easily over time, whereas firmer pillows really give your body the support it needs and will last longer.

Our Verdict

Overall, we found the Calming Comfort Cooling Knee Pillow to be the very best knee pillow you can buy today. Its super sophisticated design, complete with cooling gel and premium memory foam, really helps it to stand out. The comfort and support levels provided by this knee pillow are second to none.

The silver medal goes to the ComfiLife Orthopedic Knee Pillow for Sciatica Relief. One of the best knee pillows for back pain and sciatica, this pillow offers exceptional support for all those aches, pains, and discomforts that can really pose a problem in the night.

Last but not least, the NATUMAX Knee Pillow for Side Sleepers was our third favorite knee pillow. Its plush velvet exterior makes it one of the comfiest knee pillows around, and its firm memory foam construction, plus the addition of a useful strap on the side, makes it highly effective for side sleepers.
