Guide to Best Knee Pillow for Side Sleepers 2023

If you like to sleep on your side, then you know that getting comfortable can be a bit challenging at times. One of the primary issues with side sleeping is that you create pressure points on your body, most notably on your hips and your knees. Since your legs are pressed together, they can get sore and painful throughout the night, causing you to toss and turn.

Another issue with sleeping in this position is that it can misalign your back and create lower back problems as well. Fortunately, there is a quick and easy solution to this – a knee pillow.

Knee pillows are designed to alleviate the pressure caused by sleeping on your side by padding your legs and ensuring that your spine is correctly aligned all night. Now, instead of having to switch positions throughout the night, you can sleep soundly and wake up feeling refreshed.

So, with that in mind, we want to take a look at the best knee pillow for side sleepers. These products are designed to be extra comfortable and suitable for all people, so you’re sure to find one that works for you. Let’s transform the way you sleep.

Find Out How to Choose a Knee Pillow


Technically speaking, you can achieve similar results by sticking any regular pillow between your legs while you sleep, but the fact is that doing this won’t solve the problem. Instead, it will make it a little better until the pillow gets too flat, defeating the whole purpose.

Instead, it’s much better to get a pillow that is shaped for your knees. For the most part, these products have square sides and a soft slope in the middle so that you can get the comfort and support you need without having to reposition it throughout the night.

There are also other knee pillows that can be used in different positions as well. If you switch between sleeping on your side and your back, it can be beneficial to have a cylindrical model instead because you can support your legs in either position.

Overall, when picking out the best knee pillow, you have to determine what’s best for your habits. If you want versatility, pick a model that allows for that. Also, choose one that contours well to your natural body shape.


For the most part, pillows these days are made of soft memory foam. Because this material is already designed to alleviate pressure points and cradle your body, it makes sense that it would work well for knee pillows as well.

However, there are some downsides to memory foam, which means that you may want to pick a different type of foam instead. Usually, pure memory foam can sleep hot, which can wake you as your body heats up. Also, it can have a bit of a chemical smell, so that can be an issue for some people.

Fortunately, there is a wide selection of different foams out there, including those that are more eco-friendly and less heat absorbent. Choosing the right material will ensure that you sleep peacefully without any problems.


If you happen to move a lot while sleeping, then you want to make sure that your knee pillow won’t either slip out of your legs or get misaligned during the night. If you’re worried about losing your pillow and waking up because your legs are not supported, then you may consider buying one with a strap.

Typically speaking, these straps are made of Velcro adhesives and ensure that the pillow stays in place all night long. Also, if you switch sides, you can do so more easily with a strap because your legs will stay together.

For some people, straps can feel a bit odd, while others like the extra feeling of security. If you’re not sure how you’ll react to them, we suggest trying them out first before committing to it.

Also, if you don’t move around much, it may not be necessary at all.


Although your knee pillow will compress slightly while you’re sleeping, some models are firmer than others. Thus, if you get one that is too wide, it may create more problems because your hips are still out of alignment.

It can be challenging to determine the right size without trying, but most professionals recommend between four and six inches of separation. Also, depending on your body type, you may want a pillow that accommodates your leg girth.

Overall, you want to consider these things when choosing the right size.

Firmness – softer memory foam will compress more, meaning that your legs will be closer together, especially after a few months of using it.

Leg Width – if you have more massive legs, then you will put more weight on the pillow, requiring more firmness and a wider model.

ComfiLife Orthopedic Knee Pillow for Sciatica Relief, Back Pain, Leg Pain, Pregnancy, Hip and Joint Pain

For the most part, the best knee pillow for side sleepers are going to be ergonomically shaped so that you get the support and comfort you need. While getting a wedge or multi-use pillow is suitable for those who sleep in different positions, side sleeping needs something explicitly designed for that.

One thing that we like about this particular model is that it’s made of high-density foam, meaning that compression and support shouldn’t be an issue for most users.

Leg Knee Pillow by Get Safe – For Side Sleepers

When picking out the best knee pillow for side sleepers, you can either get a shape that is heavily or slightly contoured. There are benefits and downsides for both, so you may want to try each one to see which will work best for you.

Pillows with a smoother shape like this one from Get Safe are excellent because they don’t feel too intrusive while you’re sleeping. While other pads can stay in place much more easily, they can seem a bit constrictive, which can be a problem for some users. However, if you like to shift and move around, this shape will work a little better.

Overall, this pillow is a bit softer and more plush than the others, so if you want more comfort, then this is a better choice. Some of these models can feel a bit too firm, which can make it harder to find the right position, so this unit should work for almost anyone.
