Buying Guide

You’ve seen our knee pillow reviews, so now let’s look at how to choose the right option for you. This knee pillow buying guide will take a look at why you might want to get a knee pillow to improve your sleep, as well as analyzing and highlighting the various factors and features to consider in order to choose the best pillow.

How a knee pillow can improve your sleep

7 Supportive Knee Pillows for Comfort and Pain ReliefA knee pillow can provide a lot of great benefits, including:

  • Pain Relief - The main reason people choose to sleep with a knee pillow is for pain relief. These pillows can help with everything from pregnancy pains to sciatica, injuries, and other back or leg pains.
  • Alignment - Knee pillows assist with providing proper spinal alignment, which can help those who have spinal problems or other related issues.
  • Comfort and Support - A strong knee pillow like the Cushy Form Knee Pillow for Side Sleepers provides added comfort through the night, and many people, even without any kind of bodily pains, can appreciate the support these pillows provide.
  • Better Circulation - Good quality knee pillows are able to improve circulation around the legs and body, improving your overall health and reducing aches and discomforts in muscles and sore spots.
  • Multiple Uses - You don’t even necessarily have to use your knee pillow while sleeping. It can be of great use simply while sitting or lying down to rest, relax, meditate, watch TV, read a book, and more.

Features to consider when choosing a knee pillow

When shopping for a good quality knee pillow like the Cushy Form Knee Pillow, you need to think about a lot of different factors and features. It’s important to consider each factor and decide how highly you value it. Some people will care greatly about the shape of the knee pillow, for example, while others will put more emphasis on its durability or the materials that have been used to fill it. Read on to learn more about all of the main features of knee pillows.

Shape and comfort

7 Supportive Knee Pillows for Comfort and Pain ReliefKnee pillows come in two main shapes: the bolster, half-moon shapes and the contoured, wedge-like shapes. Neither of these options is necessarily better than the other, but they are better suited to certain situations. The bolster shape, for example, is better for back sleepers as it slides under the knees and has a flat base to be placed on your mattress, while the contoured shape is a good option for side sleepers as it fits snugly between the legs. Both options can work for you, but the important thing is to find a knee pillow with a good ergonomic design and a lot of comfort, like the Cushy Form Knee Pillow for Side Sleepers.

Construction, materials, and density

Typically, knee pillows are made from either memory foam or regular foam. Memory foam contours and shapes around your body, keeping its shape and adapting to you over time, whereas regular foam is designed to reform in its original shape each time. Good quality knee pillows like the Knee-T Medical Grade Knee Pillow for Side Sleepers will contain long-lasting, durable foam that can be used for years without losing its shape. You also need to consider whether or not your pillow has any cooling properties and will be breathable and cool in the night, or whether it might get hot and be uncomfortable for you.

Cover fabric

Since you’re going to be sleeping with the knee pillow each night, the cover fabric can be a very significant factor as it may be in contact with your skin quite a lot and will therefore need to be soft, comfortable to the touch, and breathable too. Ideally, you’ll want a cover that can be easily removed and washed in a washing machine, purely for your own convenience and for the cleanliness of the pillow. It’s also wise to try and find a breathable, hygienic cover that stays cool through the night, as seen on the Calming Comfort Cooling Knee Pillow.

Sleeping position

7 Supportive Knee Pillows for Comfort and Pain ReliefYour own sleeping position is another important thing to think about when buying a knee pillow, as some pillow styles and shapes are better suited to certain sleeping positions. For example, the bolster style pillows are better for back sleepers, while the contoured pillows like the Cushion Lab Extra Dense Orthopedic Knee Pillow, are good for side sleepers. If you’re a combo sleeper and tend to switch positions in the night, the bolster pillow is probably the better option as it offers a little more versatility. You should also consider getting a knee pillow with a strap, as this helps it to stay in place as you move around in the night.

Dimensions

The size of your knee pillow is another interesting feature to think about. Some people prefer larger pillows as they can offer more flexibility and allow the sleeper to move around a little more in the night without losing the pillow. Others favor a smaller knee pillow like the Contour Legacy Deluxe Cool Leg Pillow, due to its more compact, portable, and convenient nature, taking up less space in the bed.

Extra features

Knee pillows may also come with a range of useful extra features for you to consider. Some of them will come with a pillow strap, like the Lenora Half Moon Bolster Pillow, for example, letting you essentially wrap the pillow around your legs and keep it held in place all night long, so you never have to worry about it falling out of position and waking up feeling pain or discomfort. Some knee pillows may also ship with extra covers for you to switch out, and some feature cooling gel layers, travel cases, hypoallergenic covers, and more.

FAQ

The answer to this question really depends on your own personal preferences. Some people tend to favor a firmer knee pillow, while others prefer their pillows to be softer. If you want to get the best results in terms of pain relief and alignment from your knee pillow, you’ll need it to be sufficiently firm. A soft pillow will simply flatten under your knees and fail to provide the level of support you require. So, if you’re faced with a decision between two pillows, the firmer one is usually the best option.

In general, the actual pillow probably won’t be washable. Many of the best knee pillows are made from foams and memory foams that aren’t suitable for machine washing and can be damaged or negatively affected by a wash. Fortunately, most good quality knee pillows will come with removable covers which can then usually be washed in a washing machine. Pillows can get dirty over time, with experts recommending that they be washed on a monthly basis or more frequently, depending on your own habits and preferences.

The great thing about a good quality knee pillow is that it can be used in various ways. These pillows can be placed both beneath the knees and between the legs and provide the same great benefits, so you don’t have to worry that one is better than the other. Try both options and see what suits you. You may also find that your sleeping position affects the usefulness of each position. For example, side sleepers will get better benefits from placing the knee pillow between their knees.

Our Verdict

Overall, our favorite knee pillow is the Cushy Form Knee Pillow for Side Sleepers. With its strong, memory foam design, this knee pillow holds its shape well and offers just the right amounts of firmness, comfort, and support to provide dramatic relief from various bodily pains around the back and hips.

Finally, the third top rated knee pillow on our list is the Knee-T Medical Grade Knee Pillow for Side Sleepers. Designed by medical professionals, this knee pillow is the best option for side sleepers. It slips seamlessly between the knees and stays there all night long, thanks to the fitted strap, and it also features a highly breathable bamboo cover.
