Why you need a Knee Support Pillow when sleeping on you Side


Sleeping with a pillow under the knees or between your legs isn’t just incredibly comfortable - it can dramatically improve the quality of your rest. Sleep is one of the most critical parts of our lives, and we need to do it well if we’re going to function at 100%! Here are some ways that using a pillow between the legs can help you sleep better and longer.


Promotes Good Posture

We’re often taught the importance of good posture when sitting upright. It helps our back and legs rest properly and avoids placing strain on the wrong areas.
Good posture while we sleep however, receives less attention - However, it’s just as important as maintaining good posture while you’re sitting in an upright position on a chair of couch.
Using a knee support pillow between your legs while sleeping helps promote good posture, meaning that every part of your body gets the rest it deserves and pressure is removed from body parts that otherwise are still on strain while you sleep. This is especially true of our legs — how many times have you woken up feeling like your legs have just finished a 10-hour shift  at work or a 8 mile hike? This happens when we rest in a position that doesn’t let our muscles heal and relax the way it needs it.
Using a cushion between your legs, helps to keep your legs separate and supported when you sleep on your side. This allows the muscles to relax and recuperate overnight. A knee pillow is especially beneficial for side sleepers. It can mean that one leg presses against the other and puts strain on a muscle or tendon when they should be apart and relaxed. Sometimes this can also result in pain of your knees as they are pressed together :(


Supports a Deeper Sleep

Deep Sleep

We know when we’re uncomfortable, even when we’re asleep. This is why you keep waking up when you rest on a poor-quality mattress or when your neck isn't supported properly. This is your body telling you that you need to make adjustments for it to heal correctly and be in balance with it's natural alignment.

You can let your body know that it’s being taken care of by using a knee pillow. It will:

  • Prevent your legs from touching and putting pressure on each other
  • Spread out the concentrated weight of your legs and prevent them from pushing “too hard” into your mattress
  • Prevent your body heat from getting trapped between your legs, creating sweat and odor in some cases
  • Minimizes the risk of sleeping with any “sensitive parts” getting trapped between your legs, potentially causing unwanted and uncomfortable pressure
  • Reduce the chance of your feet or ankles touching - these are harder and bonier parts that may wake you up when in discomfort

A well-designed knee pillow for sleeping can help you achieve deeper, more restful sleep. In turn, this helps your body heal and will mean that you wake up every morning feeling energized and ready to tackle the day.


Mediating Temperature

Mediating Temperature

Your body temperature is another important factor in helping you get a good night’s rest. We all experience night time body temperature differently — some people feel very cold when they’re ready for bed and need a hot water bottle and thick blankets to get comfy. Others find their internal temperature to skyrocket, and a thin sheet is all they end up needing.

Whether you're a hot sleeper or need to get cozy warm in bed, sleeping with a pillow between the legs is a great way to mediate your body temperature.

  • If you typically feel very cold when you go to bed, an additional soft cushion under the knees can provide some much-needed comfort. The cushion will gain some warmth from contact with your body, and the soft fabric and filling provide a lovely warming sensation.
  • If you tend to feel too hot before you rest, sleeping with a millet hulls filled knee pillow between legs helps prevent your body(specially your legs) from overheating. Your legs will give out heat when you’re trying to rest — without a proper leg pillow, this creates a vicious cycle of your legs warming each other. This can rapidly lead to uncomfortable sweats and ultimately wake you up in the middle of the night. A knee pillow for side sleepers helps to keep your legs separate and gives the heat somewhere to go, and it in return eliminates sweaty surprises.

Using a knee pillow for sleeping is a great way to keep an even, comfortable temperature when you’re at rest. An easy-to-clean, removable cover is always a great idea as this prevents sweat from building up in the pillowcase which can lead to mold built up.


Providing Comfort

It’s not just physical comfort that helps us sleep. We won’t get too deep into the psychology of sleep here — suffice to say that a leg pillow provides the same type of comforting benefits as a full-body pillow model but doesn’t get in the way of your other bolsters so much.

Another huge benefit of a smaller size knee cushion is that full-body pillows are harder to maneuver if you roll from one side to the other. A lightweight knee pillow for side sleepers will move easily with the rhythm of your body, ensuring that you don’t wake up when you roll over.


Easing Pain and Soreness

Sleep can be uncomfortable for various reasons. It’s not just about preventing your knees from putting pressure on each other — it’s about the whole body and buying a cushion that will actually help you get a good night’s rest.

Conditions like sciatica and scoliosis make comfortable nights of sleep more challenging. Knee pillows can provide support where needed and allow you to find a stable position. Pregnant women often benefit from leg pillows or full-body pillow options as they can take the weight off uncomfortable parts of the body.

Whatever your circumstances, sleeping with a pillow between legs is a great way to give yourself the best night’s rest possible. It’s recommended for everyone interested in waking up with a rested body rather than more pains. 


What to consider when shopping for Knee Pillows

The best choice should be made of a soft, breathable fabric. This will help it regulate your body temperature when you’re resting. Material that is pleasant to touch is also essential, of course — whatever your reason for sleeping with a pillow between legs, it’s got to feel good to you!

The best leg pillow will be made of a breathable, organic material that is soft to the touch and easy to clean.




People commonly search for a knee pillow for side sleepers because full body pillow models aren’t for everyone, despite their benefits they are also huuuuuge. When choosing your leg pillow, you should keep this in mind — smaller options that give optimal cushioning to your knees are best and preferred by majority of consumers.

Smaller designs help to keep your legs separate and promote comfort, but you’re not wrestling with a long, heavy object that makes it difficult to roll over.


Filling Options


Organic filling options such as millet hulls provide incredible softness and support without being exposed to chemicals which many times are found in memory foam products.


Manufacturing Methods


You should always check where your bedding was made and what techniques were used in its manufacturing process. The best leg pillow for side sleepers will always be a hand-made model. The quality and durability of hand-made models can’t be beaten we think.




A significant reason that people opt for a knee pillow, is that full-body size models are too heavy. Lightweight small models weighing around 1.2lbs, which means that you’ll barely notice the pillow’s weight when you sleep, even though its firm design helps you maintain the perfect sleeping posture. 

Heavier options might wake you up unduly or put too much weight on one leg.




A zipper is the best type of closure for any type of sleeping pillow, as this guarantees that you can not only remove the cover but also access the filling and adjust it to your liking.


Is it Washable


Any removable cover should be easy to wash and resistant to staining. Many people choose to sleep with a pillow between their legs because they easily overheat while they sleep — this means that any cushion they use between their legs, will be exposed to some sort of sweat at some point over it's lifetime. So regular washing of the cover, ensures your enjoy comfort and hygiene in the long run.


Hypoallergenic Properties


Organic materials tend to be hypoallergenic compared to artificial fabrics. When choosing your leg support cushion, staying away from any synthetic materials that might cause even mild allergic reactions is something to keep in mind.
