The Best Knee Pillows

FOR SIDE SLEEPERS

It’s about time you align your hips and spine, try the kneez peace for quality sleep and peace of mind.

The Best Knee Pillow for Side Sleepers – Patented Comfort & Support

Our patented knee pillow for side sleepers offers more leg positions than any other pillow on the market—making it the best knee pillow for alignment, comfort, and support. Unlike typical leg pillows, this is a true knee pillow designed specifically for side sleeping.

It prevents knee bones from touching, ensuring better hip and spine alignment for side sleepers. By distributing leg weight above and below the knees, it provides unmatched comfort and reduces pressure points—ideal for sciatica relief, hip pain, and back pain.

Made from soft, high-quality Ecoflex® memory foam, this orthopedic knee pillow is both supportive and environmentally friendly. Unique raised foam ribs line the multiple ergonomic leg channels, improving blood flow and overall comfort throughout the night.

No need for uncomfortable leg straps—our contour knee pillow stays in place naturally, thanks to the center knee depression and well-designed channels.

Available in three different thickness options, you can choose the perfect size for your sleep style and body shape.

Why Choose the Kneez Peace® Pillow?

 

Why Choose the Kneez Peace® – The Best Knee Pillow for Side Sleepers?

If you’re looking for the best knee pillow for side sleepers, the Kneez Peace® pillow is your solution for all-night comfort and proper alignment. Designed specifically for side sleepers, this orthopedic knee pillow offers unmatched support, pain relief, and pressure distribution—so you can sleep better and wake up pain-free.

What Makes the Kneez Peace® Pillow Different?

The Kneez Peace® memory foam knee pillow stands out with its soft-yet-supportive Ecoflex® foam, ultra-lightweight design, and exclusive ribbed leg channels that feel like a cloud cradling your knees and thighs.

Unlike typical U-shaped or flat leg pillows that squeeze your legs and create pressure points, the Kneez Peace® uses a 14-inch shallow ribbed channel to distribute your top leg’s weight more evenly. This reduces pressure on both legs, making it ideal for long-term use—without the discomfort.

Great for:

  • Side sleepers needing hip and spine alignment
  • Individuals with sciatica, hip pain, or lower back pain
  • Post-knee surgery recovery or injury support
  • Elevating the heel or ankle when lying on your back

Key Benefits:

  • Patented ribbed channel for superior pressure relief
  • Ecoflex® memory foam for comfort and sustainability
  • Lightweight design — no uncomfortable leg straps needed
  • Three size options to match your body and comfort preferences
  • Helps maintain proper hip, knee, and spine alignment

Whether you’re trying to improve your sleep posture, relieve pain, or simply sleep more comfortably on your side, the Kneez Peace® pillow is the top-rated knee pillow trusted by side sleepers.

The Benefits of Side Sleeping

Back Pain Relief

Side sleeping can alleviate pressure on the spine, reducing chronic back pain.

Reduced Snoring

This position helps prevent airway collapse, which can decrease snoring.

Improved Sleep Apnea

Side sleeping is beneficial for individuals with sleep apnea, as it keeps the airway open.

Pregnancy Support

It is recommended for pregnant women, especially in the later stages, to improve circulation and reduce pressure on the uterus.

Better Digestion

Sleeping on the left side may aid digestion and reduce heartburn symptoms.

These benefits highlight why many people prefer side sleeping as a comfortable and health-conscious choice.

TESTIMONIALS

⭐️⭐️⭐️⭐️⭐️

“As a physical therapist I am often asked what is the best pillow to sleep with and does it help to sleep with a pillow between my knees. I’ve struggled to find the right solution to recommend to patients until I found the Sea Leg and Kneez Peace pillows. They support the leg without increasing pressure on the joint and help to keep the legs better aligned to help patients with hip and low back pain. I recommend them to any patient with lower back, hip or knee pain that is a side sleeper!”

In June of 2024, I had extensive knee surgery and had to spend 6 weeks on crutches – non weight bearing followed by months of physical therapy. Due to the surgery, it made it difficult to sleep and whenever my knees would touch, there would be a great amount of pain due to the sensitivity of the surgery. I tried pillows, I tried leg pillows, and I tried numerous other leg support systems, but nothing seemed to work or feel comfortable. When I met Jim, he had his pillow that he wanted me to try, and it was something that was not too large and provided just enough softness and support to make it finally comfortable enough to sleep without the pain. I have been using it ever since.

Best Knee Pillow I’ve Ever Used – A Game-Changer for Side Sleepers!

After trying several knee pillows over the years, I can confidently say this one is in a league of its own. From the moment I took it out of the packaging, I could tell it was thoughtfully designed. The memory foam is perfectly balanced—soft enough to be comfortable, yet firm enough to provide proper support all night long.

What sets this knee pillow apart is its ergonomic shape. It cradles the knees just right, keeping my spine, hips, and legs aligned whether I’m sleeping on my side or shifting positions. I wake up feeling noticeably less stiff, especially in my lower back and hips. It’s made a genuine difference in my sleep quality.

The breathable, washable cover is another huge plus. It stays cool throughout the night and is super easy to clean. I also love that it doesn’t lose its shape over time—something that’s been an issue with other pillows I’ve tried. If you’re a side sleeper or struggle with hip or back pain, I can’t recommend this pillow enough. It’s a small investment for a big upgrade in comfort and sleep health.

“Why Did I Wait So Long to Get a Knee Pillow?!”

Okay, let me just say—I didn’t know how much I needed a knee pillow until I finally got one. I’ve been waking up with sore hips and a stiff lower back for months, thinking it was just part of getting older or sleeping weird. But after a friend recommended the Kneez Peace Pillow, I decided to give it a shot. Best decision ever.

From night one, I noticed the difference. The shape fits naturally between my legs and doesn’t move around or flatten out overnight. It keeps my hips aligned and relieves pressure from my lower back. Honestly, I sleep deeper and wake up feeling so much better. It even has a breathable cover that stays cool (which I didn’t know I cared about until I had it). And bonus—it doesn’t have that weird chemical smell some memory foam stuff does. It’s just… comfortable. Supportive. Simple. Exactly what I needed.

If you’re a side sleeper or deal with hip/back discomfort, seriously—get a knee pillow. This one changed my sleep for the better.

I’ve tried a lot of sleep aids over the years, but nothing compares to my Kneez Peace Pillow. From the first night, I noticed a huge difference—no more waking up with hip or lower back pain, and I stay comfortable all night long. What really surprised me is how it stays cool the entire time. I’m a hot sleeper, and this pillow somehow manages to keep its cool, which makes a big difference in staying asleep. It’s the perfect size, stays in place, and gives just the right support.

⭐️⭐️⭐️⭐️⭐️

I really like my knee pillow. I have found it helps alleviate my hip pain I experience when I sleep on my side. It keeps proper alignment from hip to my knees. It was an unexpected and pleasant surprise. The texture of the fabric is so smooth to the touch and doesn’t retain heat. The cushion is not to firm and not to soft, but just right. I give it 5 gold stars out of 5. I love it!

To all the side sleepers out there, here’s the solution to the uncomfortable and sometimes painful collision of your knee and ankle bones rubbing on each other
THE SEA LEG PILLOW
This unique fish shaped designed pillow will cushion those pressure points and allow you to have a comfortable night’s sleep. I have been using the pillow for over six months, and highly recommend the purchase.

I use the pillow with the tail between my knees, and the head on my ankles, but it will work just fine either way. Also you are able to roll over to your other side by pinching your knees together before you begin to roll to the other side, the pillow rolls with you.
For a good night’s sleep try…

⭐️⭐️⭐️⭐️⭐️

I’ve been dealing with sciatic pain for quite some time and have struggled with trying to find a comfortable position to sleep in. I’ve tried using regular pillows between my knees but never found any relief. After talking to Jim, he said to give one if his knee pillows a try. I noticed a difference after the first couple of nights, waking up without any stiffness in my lower back. I couldn’t believe how cool the material stayed all night. If you or someone you know has lower back pain give this knee pillow a chance – it’s definitely worth it.

Chris

⭐️⭐️⭐️⭐️⭐️

I just wanted to let you know how much I like your knee pillow. I have tried other knee pillows & finally found one that works for me! 

I am using the medium size & I like that it is big enough to support not only my knee, but also my calf & upper leg. The covering is so soft & smooth & feels cool throughout the night.

I would recommend this pillow to other side sleepers that don’t like their knees knocking during the night! It really helps keep your body aligned & wake up refreshed! 

Thank you! Kathy

⭐️⭐️⭐️⭐️⭐️

I have been using the Sea Leg (fish shaped pillow) for about 2 weeks now and I love it. When you sleep on your side, it supports from your knee all the way down to your ankle. I wasn’t sure if it would stay in place while I slept but it does. I highly recommend you try it and see for yourself!

Lynn

⭐️⭐️⭐️⭐️⭐️

I’ve tried multiple pillows on my knees when I sleep but this is by far the best I’ve found. I had sciatic nerve issues and had been using a pillow between my legs when sleeping to help keep my legs aligned and relieve pressure on my lower back. This pillow has really been a game changer for me. The pillow has a breathable cover that stays cool when you sleep, its not bulky so when you rollover it doesn’t wake you every time you move. The memory foam fits to you and your body. It’s easy to pack up and travel with so it’s been awesome for me. I feel better and would highly recommend to anyone who is a side sleeper or has had sciatic issues.
Feeling better and more refreshed daily has been great for me both physically and mentally so thanks Jim for a great product that we can all benefit from!

Teresa

⭐️⭐️⭐️⭐️⭐️

I’ve been using this knee pillow for a few months, and it has made a noticeable difference for my hips and low back. It’s super comfortable, lightweight and stays cool all night. It has really helped with my hip alignment. Highly recommend this to anyone dealing with lower back or hip discomfort.

Lauren

⭐️⭐️⭐️⭐️⭐️

I absolutely love, love, love my Sea Leg Pillow.  The last two nights I slept soooooo good!  I used to toss all night and be so restless.  Now I don’t move.  Best money I ever spent!
Cindy

⭐️⭐️⭐️⭐️⭐️

Jim gave me a Kneez Peace pillow after I pulled something in my lower back. I have used it for a few weeks now and have had great relief from it. I’d highly recommend this pillow to anyone that is experiencing hip or back pain.
