Hip discomfort can make side sleeping harder, especially when your top leg falls forward and twists your pelvis. A cushion placed between your legs may help keep your hips and knees in a more comfortable position. The options below range from compact knee pillows to a full-length leg cushion, so you can compare the support style, fit, and features that matter for your sleep position.
A pillow is not a substitute for medical care, and comfort varies from person to person. If your pain is severe, persistent, or getting worse, ask a healthcare professional what may be causing it and which sleep position is appropriate for you.

Our Picks: Best Cushion For Hip Pain While Sleeping reviews
5 STARS UNITED: A Compact, Versatile Knee Pillow
This compact memory foam pillow is designed to sit between your legs and help keep your knees and hips in a more comfortable position while you sleep on your side. It measures 9.8 by 7.8 by 6 inches, making it a smaller option than the full-length leg cushion in this guide.
The company describes four possible placements: between the knees, under the lower or upper leg, between the calves, or beneath the knees when lying on your back. That flexibility may be useful if you are still figuring out which position feels best. The cover is breathable, anti-pill, and washable. The product is also described as OEKO-TEX STANDARD 100 and CertiPUR certified.
One important detail: this pillow does not include a leg strap. If you move around a lot at night, you may need to reposition it. Compared with strap-equipped options such as the NATUMAX and TULARIS, this one keeps the setup simple but offers less help keeping the cushion in place.
Pros:
- Compact size with several suggested sleeping positions
- Memory foam contours to the legs
- Washable, breathable cover
- Certifications are listed for the foam and materials
Cons:
- No strap to hold it in position
- Its compact shape does not support the full leg
Verdict: Choose this pillow if you want a small, adaptable cushion and do not require a strap to keep it between your legs.
NATUMAX: A Strap-Equipped Pillow with Sleep Accessories
The NATUMAX is a memory foam knee pillow made to fit between your legs. Its contoured shape is intended to support a more aligned position for your hips, knees, and back while side sleeping. You can place it above or below your knees, depending on where you prefer the cushion.
A leg strap is included to help keep the pillow aligned if you shift during sleep. Its breathable, zippered cover is machine washable; the foam itself should be spot cleaned and allowed to air dry. The package also includes a sleep mask and ear plugs, making this a broader sleep-comfort set than the other compact pillows here.
The main trade-off is that it provides support in a smaller area than a full-length cushion. The supplied details also do not list its dimensions, so check the product listing if exact sizing is important to you. Its strap and included accessories distinguish it from the strap-free 5 STARS UNITED option.
Pros:
- Leg strap helps hold the pillow in position
- Can be placed above or below the knees
- Machine-washable zippered cover
- Includes a sleep mask and ear plugs
Cons:
- Does not provide full-length leg support
- Foam requires spot cleaning rather than machine washing
Verdict: Consider the NATUMAX if you want a compact knee pillow with a strap and appreciate the included sleep accessories.
Xtra-Comfort: Full-Length Support from Hip to Ankle
Unlike a small knee pillow, the Xtra-Comfort is a 29-by-11-by-4-inch cushion designed to support the legs from hip to ankle. Its full-length shape may suit you if you want to cushion more than the space between your knees. The product is described as developed and patented by a physical therapist.
Dual center contours and a rounded top are intended to cradle the legs, knees, and ankles, while angled cutouts allow you to bend and straighten your legs. An adjustable strap helps secure the pillow as you move. The high-density memory foam is designed to provide pressure-relieving support, and the breathable, moisture-wicking cover is removable and machine washable.
The larger shape is the key advantage, but it also takes up more bed space than a compact cushion. It may be more support than you need if your main goal is simply to separate your knees. The product listing also describes a 60-day guarantee, which is a useful point to check when comparing purchase terms.
Pros:
- Supports the legs along their full length
- Adjustable strap helps keep the cushion positioned
- Contoured shape allows leg movement
- Removable, machine-washable cover
Cons:
- Larger than a standard knee pillow and may take up more bed space
- May be unnecessary if you only want cushioning between your knees
Verdict: Pick the Xtra-Comfort if you want a single cushion to support your legs from hip to ankle and have room for its longer design.
TULARIS: A Contoured Knee Pillow with an Adjustable Strap
This heart-shaped memory foam pillow is sized at 10 by 9.5 by 5 inches and is designed to fit between the knees. Its contoured shape aims to support the legs and encourage a comfortable position for the hips and spine while side sleeping.
An adjustable strap with an extension is included to help keep the cushion in place. The foam is described as high-density, and the removable cover is breathable and machine washable. The product information notes that the feel of the support may take some getting used to, so it may be sensible to try the pillow consistently for several nights before deciding whether its shape suits you.
Compared with the NATUMAX, this option has listed dimensions and an adjustable strap with an extension, but it does not include the same sleep accessories. Like other compact pillows, it will not cradle the entire leg the way the Xtra-Comfort does.
Pros:
- Contoured heart shape fits between the knees
- Adjustable strap with an extension helps hold it in place
- Removable, machine-washable cover
- Listed dimensions help you judge its size
Cons:
- The support may take time to get used to
- Provides less leg coverage than a full-length pillow
Verdict: The TULARIS is a practical choice if you want a compact, contoured pillow with an adjustable strap and a washable cover.
SofterCharm: A Gel Memory Foam Option for Cool-Feeling Comfort
The SofterCharm is a contoured cushion designed to sit between your knees. Its high-density memory foam is intended to adapt to your leg shape, while a wide gel layer and breathable fabric are designed to provide a cool-to-the-touch feel. The cover is machine washable.
Its heart-shaped design is meant to fit around the legs and move with you as you shift. That makes it an option to consider if you prefer a compact pillow but want cooling features. The supplied details do not list dimensions or a strap, so compare its size and how you plan to keep it positioned with the strap-equipped TULARIS and NATUMAX models.
Cooling materials can change the surface feel, but they do not guarantee that you will sleep cooler. If you need support from your hip down to your ankle, the full-length Xtra-Comfort is a more suitable shape to compare.
Pros:
- Gel layer is designed to provide a cool-to-the-touch feel
- Contoured memory foam fits between the knees
- Machine-washable cover
- Compact style is suited to side sleeping
Cons:
- Dimensions are not provided in the supplied product details
- No strap is listed, and it does not offer full-leg support
Verdict: Choose the SofterCharm if you want a compact knee pillow with a gel layer and breathable cover, and do not need a listed strap or full-length support.
How to Choose a Cushion for Hip Pain While Sleeping
Decide How Much of Your Leg Needs Support
A compact knee pillow separates your legs around the knees and is usually the simpler option to position in bed. A full-length cushion can support more of your leg, from hip to ankle, but takes up more room. Think about whether you want targeted cushioning between your knees or support along a longer section of your legs.
Match the Cushion to Your Sleep Position
Most of these products are designed mainly for side sleeping. If you sleep on your back, look for a pillow whose instructions describe a suitable placement beneath your knees, such as the 5 STARS UNITED cushion. Consider whether you change positions during the night, since a pillow designed for one placement may need to be adjusted when you roll over.
Consider Whether You Need a Strap
A strap can help keep a compact pillow aligned between your legs when you move. The NATUMAX and TULARIS include straps, and the Xtra-Comfort has an adjustable strap for its full-length design. The 5 STARS UNITED product description specifically says it does not include a strap. If you prefer not to attach anything around your legs, a strap-free model may be a better fit.
Check the Pillow’s Size and Shape
A cushion that feels too bulky or too narrow may not suit your body or mattress. Compare listed dimensions with the space between your legs and the amount of support you want. The full-length Xtra-Comfort has listed measurements, as do the 5 STARS UNITED and TULARIS pillows. The supplied details for the NATUMAX and SofterCharm do not include dimensions, so check the product listing before choosing if size is a deciding factor.
Think About Foam Feel and Temperature
Memory foam is designed to contour to your legs, but firmness and comfort are personal. Some models emphasize high-density foam, while the SofterCharm adds a gel layer intended to feel cool to the touch. If you tend to feel warm at night, a breathable or cooling cover may be worth considering, though it cannot promise a cooler night for every sleeper.
Look at Cover Care and Cleaning
Washable covers make routine cleaning easier. The listed pillows have removable or zippered covers described as machine washable. For the NATUMAX, the foam should be spot cleaned and air dried rather than put in the washing machine. Check the care instructions for the exact product before cleaning, especially if you are unsure whether the foam or only the cover is washable.
Choose Support for Comfort, Not as a Diagnosis
A leg cushion may help some people find a more comfortable sleeping position, but hip pain can have many causes. Treat a pillow as a comfort aid rather than a cure. If pain continues, limits your movement, or is accompanied by other concerning symptoms, speak with a healthcare professional.
Frequently Asked Questions
Can a pillow between the knees help with hip discomfort?
It may help some side sleepers keep their legs in a more comfortable position and reduce the feeling of pressure or twisting. Results depend on the person and the cause of the discomfort, so a pillow should not be treated as a guaranteed solution.
Should I choose a knee pillow or a full-length leg pillow?
A knee pillow is compact and focuses on the space between your knees. A full-length pillow supports a larger portion of your legs and may be preferable if you want support from hip to ankle. Consider your bed space and how much coverage you want.
Do these cushions work for back sleepers?
Some may be used in other positions. The 5 STARS UNITED product description suggests placing it beneath the knees for back sleeping. The other products are primarily described for side sleepers, so follow the instructions for your chosen model and stop using it if it causes discomfort.
Will a strap keep the pillow in place all night?
A strap is intended to help keep a pillow aligned, but it cannot guarantee that the cushion will stay in the same position for every sleeper. NATUMAX, TULARIS, and Xtra-Comfort list straps; the 5 STARS UNITED pillow does not include one.
Can I wash the memory foam pillow?
Care instructions vary by product. The NATUMAX description says to spot clean the foam and air dry it, while its cover is machine washable. Several other options have removable, washable covers. Check the instructions for your specific pillow before washing any part of it.
How long does it take to get used to a knee pillow?
That varies. The TULARIS product information notes that adjustment may take several nights. Try positioning the cushion as directed, and discontinue use if it increases discomfort.
When should I talk to a healthcare professional about hip pain?
Consider seeking medical advice if your pain is severe, persistent, worsening, or affecting daily activities. A professional can help assess the cause and advise you on appropriate sleep positions and support.
Final Recommendation
For a compact cushion with several suggested placements, the 5 STARS UNITED is a flexible option, though it has no strap. If keeping a pillow aligned is important, compare the strap-equipped NATUMAX and TULARIS. For broader support from hip to ankle, the Xtra-Comfort’s full-length design stands apart. The SofterCharm is worth considering if a gel layer and cool-to-the-touch feel are priorities. Choose the shape and features that match your sleep position, available bed space, and comfort needs.
