When you sleep on your side, your top leg naturally drops forward. This twists your hips and spine, putting pressure on your lower back, hips, and knees. The Kopflo Cradle™ Knee Pillow keeps your legs properly aligned while you sleep. Its contoured memory foam design gently separates the knees and supports the top leg, helping your spine stay in a natural, balanced position throughout the night. The result is deeper, more comfortable sleep with less strain on your hips and lower back.

Overview

The Kopflo Cradle™ is an ergonomic knee pillow designed to improve spinal alignment for side sleepers.

Placed between your knees, it elevates the top leg to keep your hips stacked and your spine aligned. This reduces pressure on the lower back, hips, and knees while preventing uncomfortable bone-on-bone contact between the knees.

The contoured shape naturally fits between the legs, while the adjustable strap keeps the pillow securely in place throughout the night.

Ideal for side sleepers experiencing lower back pain, hip discomfort, sciatica, or pregnancy-related sleep pressure.

Care

Remove the cover using the zipper and machine wash on a gentle cycle with cold water and mild detergent.

Air dry or tumble dry on low heat.

Do not wash the foam core. If needed, wipe gently with a damp cloth and allow it to fully air dry.

Materials

Supportive Memory Foam Core
Maintains its shape while supporting the weight of your legs, helping keep your hips and spine properly aligned throughout the night.

Breathable Fabric Cover
Soft, breathable fabric with mesh side panels to improve airflow and prevent heat buildup between the legs.

The removable cover keeps the pillow easy to clean and fresh for daily use.

Wake Up Without Hip or Back Pain

When sleeping on your side, the top leg naturally drops forward, pulling the hips out of alignment and putting strain on the lower back and knees. The Kopflo Cradle™ Knee Pillow keeps your legs properly supported by gently separating the knees and maintaining natural hip alignment. This helps keep your spine balanced throughout the night, reducing pressure on your hips, knees, and lower back so you can sleep more comfortably and wake up feeling rested instead of stiff or sore.

Alignment while you sleep

Stacked Hips, Straight Spine.

Between the knees, the contour elevates the top leg so the hips stay stacked instead of twisting forward. That single change takes rotational pressure off the lower back, hips, and knees — the mechanics behind most side-sleeper morning aches.

Stays put through the night

Strapped In, Not Chased.

The adjustable elastic strap holds the pillow to your leg, so it's still there when you shift at 3 a.m. — the failure point of loose knee pillows. The cover zips off for washing.

My hip and back pain stopped

Side sleeping left my hips and lower back aching every morning. Popping this between my knees lined me up and the pain was gone within a week.

No more waking up sore

It keeps my hips stacked so my back stays straight all night. I stopped waking up stiff, and the strap means it never slips out of place.

Fixed my morning hip ache

I'd wake up needing to stretch my hip out every day. With this my legs stay aligned and that ache just isn't there anymore.

Frequently asked questions

Why do side sleepers need a knee pillow?
Without support between the knees, the top leg drops forward and rotates the pelvis, twisting the spine. A knee pillow keeps the hips stacked and aligned, which takes pressure off the lower back, hips, and knees.
Will it stay in place while I sleep?
Yes — the adjustable elastic strap secures the pillow to your leg, so it moves with you instead of ending up on the floor. That's the main failure of strapless knee pillows.
Can it help with lower back or hip pain?
Many side sleepers feel relief because the pillow keeps the spine aligned and reduces pressure on the hips and lower back overnight. It addresses the positional cause, so give it a few nights of consistent use.
Is it comfortable for all body types?
The contoured shape fits naturally between the legs and the strap adjusts to fit most users. It's also a common pick during pregnancy, when hip and pelvic pressure make side sleeping uncomfortable.
Does it help with sciatica?
Sciatic pain often worsens when the top leg pulls the pelvis into rotation at night. Keeping the knees separated and the hips level reduces that nerve-aggravating twist — many people with sciatica report calmer nights. Persistent symptoms still warrant a doctor's visit.

I have a slipped disc and I’m usually in a bit of pain when waking up in the morning. This pillow helps relieve a lot of that pain. I was very skeptical, but I’m happy I gave it a try. It allows you to move around and it’s not too bulky. I would highly recommend this.

This relieved my pain by so much that I'm not stuck in bed hours after waking up. I have no complaints. I'm 5'5" and about 215 lbs.

i’ve been dealing with bad knees for quite some time, and stacked pillows just weren’t doing the trick. after using a similar pillow at my chiropractor’s office and asked him where u got it from, I went on koplfo and ordered a couple, rest assured, this is it! Amazing product, thank you!

This pillow gets a lot of use. My husband tried it to alleviate hip pain and it was great, then our big boy ralf got hold of it and now I need to order 2 more, great pillow. The family loves it.

I'm a very thin 5'4" woman and the size worked perfectly for me. It's a good shape, can move it up and down the legs depending on where pressure relief is needed, and it holds its shape well. Relatively inexpensive and a great value, I've been using it for 1y and just ordered another one, I sleep with it almost every night, and I find it resolves a lot of hip and knee pain that have made sleep difficult. Photo for size reference. Happy with my product. Wish I had this during pregnancy!!

I just used this for the first time. I could not believe the difference it made for my sciatic nerve problem. I slept on the opposite side, used the cushion without the strap ( and it stayed in place!), and I was able to wake up and move my leg, get out of bed with no trouble. This is the first time in 2 years I am able to do this! Great product!!!

This is a perfect knee pillow! At first, I thought it might be too bulky but the pillow material condenses to fit your legs. Plus, I love the strap which attaches the pillow to your leg. That eliminates having to find the pillow when you turn over.

Much better than using a regular pillow between the legs lol. Stays in place and feels supportive, the shape is great too.

The contour shape makes sense once you try it. Fits naturally between the knees.
