    Common Questions About The Orthopedic Knee Pillow

    How do you use a knee pillow?

    Knee pillows bring ideal alignment throughout the night, especially for side sleepers. The best way to use a knee pillow is to place it between your knees in a slightly forward bent position, which should allow your hips to rest in a neutral position. The contoured knee pillow is designed with an hourglass shape to take the pressure of your upper leg off your hips, to bring proper spinal alignment, and to decrease lower back pain.

    What does putting a pillow between your knees do?

    There are many benefits to sleeping with a pillow between your knees. Putting a firm pillow between your knees helps to keep them aligned along with your spine. Additionally, it may also reduce stress on your hips. If you are experiencing poor spinal alignment, bad sleep posture, or knee pain, consider using an orthopedic knee pillow to alleviate some discomfort. Bring maxium support for joint pain throughout the night and try our Coop Orthopedic Knee Pillow now with a 100 days risk-free trial.

    Can I use a regular pillow instead of a knee pillow?

    Although placing a traditional pillow between your legs when sleeping may provide some pain relief, our knee pillows are specifically designed to enhance pressure relief and bring maximum support for knee pain, leg pain, or hip pain. At Coop Home Goods, our solid memory foam knee pillow insert can be adjusted for any sleep position so that all types of sleepers can find an elevation level that is comfortable for them.

    Love the Adjustability

    It took me a while to figure out the exact configuration of the inserts, but now I consistently have less knee and hip pain.

    this thing is huge

    The shape is good, feel is good, but the thing is probably 25-35% larger than it needs to be. Just TOO big. I requested a refund and this was granted easily and quickly. Thanks for the good service on that. When you make a smaller version of this, let me know.

    FINALLY - the best knee pillow ever

    THANK YOU! I've been searching for YEARS for thick, study pillow. Pregnancy ruined my hips. This is exactly what I needed. THANK YOU!

    Exceeded my expectations

    I’m a side sleeper and have been having hip pain for sometime. In researching for some relief, I came across Coop and decided to give it a try. The curvature of the pillow made sense to me and I like the fact that it came with a removable washable cover. Initially I was a little hesitant given its size, and didn’t think it would stay in place throughout the night as I tend to move a lot when I sleep. However, I was pleasantly surprised and woke up, rested and pain-free. I’d definitely recommend this pillow for side sleepers.
