- The Original Long Knee Pillow for Side Sleepers. We pioneered the 14-inch long knee pillow, a design that is now widely copied. It’s the only one that does its job, covering the full thigh and knee to keep your legs in a neutral position. You don’t need two to achieve the same effect.
- Smooth Spine Alignment Pillow for Side Sleeper: As a side sleeper, there’s great chance you feel hard to fall into sleep due to the unstraight sleep posture. Our smooth spine leg pillow is good to prevent your top leg drooping sleeping on the side and keep your spine neutral when sleeping.
- Adaptive Knee Pillow for sleeping : Made deeper semi-circle shape to embrace the thighs ergonomically, designed to be longer and wider to better separate and support your knees when bending.
- Convenient to Use: If using a towel roll, you always have to adjust its thickness and it’s easy to lose its shape during sleep. Our Orthopedic Pillow is meant to be used for separation, so it has a fixed thickness 3″. It’s more convenient.
- Vast Application: The leg pillows for sleeping can be used in multiple ways and our knee pillows for sleeping always keep you company.

J’ai essayé quelques produits du genre et celui-ci est vraiment bien. C’est surtout la longueur qui me plait beaucoup étant très grand. La seule chose que je trouve qui lui manque est une sangle. Le coussin reste ferme durant l’utilisation.

The Long 14” Knee Pillow by anzhixiu is a game changer in my sleeping.
I’m a 76 yr old male who has been suffering with sciatica lately and I recently saw in an unrelated commercial that this problem may be relieved with a foam pillow used between a persons knees. I have rods and screws in my lumbar, but that has not created sciatic since 2015 when I had that surgery. For several years I have used a little travel pillow between my knees for some comfort of knee on knee, then this year I started to get pain in my right hip . I mostly sleep on my left side, knees bent. A regular bed pillow is too big and bulky besides being too soft to help. Then I saw this product and thought I would try it. INSTANTLY, no ibuprofen, the pain went away in my hip and I could finally sleep peacefully all night!
The 14″ size if perfect, supporting my knees and upper leg, along with the shape it doesn’t usually fall out of place during the night. Soft and comfortable, yet supportive, taking the pressure off my hip. The removable zippered cover is comfortable. I highly recommend this to anyone who needs some relief for sleep.

Comfortable memory foam & soft cover. Keeps legs aligned after hip surgery. I didn’t buy it until I was cleared to side sleep and it made a huge difference. You can also use it under one leg if you need to keep it elevated.
Good purchase at a good price.

Good quality, doesn’t hold the heat in, but too big for me to use.
EP –
Excellent pillow. I can only recommend.
Neato Riko –
This product remains firm throughout the night. As a plus size female with larger thighs, that is a must in order for the product to be effective for my back, hips and knees. My thighs don’t fit perfectly in the curve but still very effective. 10/10 would recommend.

Bought the larger one and using it seems to have eased hip bursitis pain, but my rheumatologist is skeptical that it has.
Neato Riko –
I bought this for use after a total hip replacement. It was a lifesaver. I still use it a year later so it is definitely well made. It is easy to take off the cover and keep clean. The foam is firm enough to support but comfortable. Well designed for sure.

Fidèle à la description, rien à redire

I’ve been using for close to 3 years now. Still has held up! Firmness is just right and is a good size! Really helps my back and hips as I have lumbar scoliosis and arthritis. I took the cover off as it was annoying to use. Now there’s just lots of pilling which is why I docked a star. Other than that I have no complaints!

TLDR;
I needed a new, second, knee pillow now that my partner has been using the original one I had. I looked up the brand of the one we already have & I think the brand dissolved when Bed Bath & Beyond went out of business. Couldn’t find another just like it. Although I found similar ones on Amazon, virtually the same design. One of those sat in my cart until I poked around a little more and came across this uniquely shaped alternative. The fact that it cushions not only the knees, but the thighs as well, appealed to me. So I bought this one (to kind of compare the difference in design). I love it! I slept so well with that and our new sheets & comforter last night 😴 Even if you’re not pregnant and never plan on becoming pregnant, your back / hips / knees will thank you for getting this.
_____
I noticed myself waking up with really sore hips in my late 20s, for no apparent reason. (Were they getting wider? I wasn’t pregnant!) And I’d notice knee discomfort as well, but it took me a while to connect the two & recognize the pattern — it specifically happened when I’d sleep on my side. I’ve always been a very restless sleeper, ending up in all kinds of positions and kind of cycling between front / back / side sleeping. At first I began using a folded pillow between my knees, and I noticed a slight improvement at first but as soon as the pillow flattened out, it made no difference. Finally, one random day in a Bed Bath & Beyond (a few years ago) I happened to come across a Reactex “cooling” knee pillow. The cooling effect was surprisingly noticeable, though subtle by design, and so great for that summer — but by now the “cooling” technology has kinda worn out it’s lifeline. The pillow is still useful as ever, and effective. So much so that my partner now uses it nightly (he’s had a lot of back and knee injuries so always wakes up in pain & he says the pillow has helped minimize that by a lot). I’d been subbing in a Squishmallow as my knee padding at night, but poor squishy is reaching the end of its lifeline too… so I needed to seriously get a dedicated knee pillow for myself.
I bought the longer of the 2 options available (in case my boo wants to trade sometimes, cus he’s got them lawng leggs) and it’s legit perfect size for me (I’m roughly 5’7″). He hasn’t tried it yet but he’s 6′ and I’m positive it would fit well for him too. The fact that this one extends to the thighs (and has many positive reviews) is maybe *the* reason I chose it over other possibilities. I swear, while everyone compliments curvy hips, they’re actually a silent curse — if my knees are at that inward, acute angle they get when they touch as I’m side-sleeping [where there’s no padding in between] I wake up so sore and I feel pain in my hips pretty much all day. So the extra thigh padding ensures a nice spaciousness (how can I say this not weirdly?), making sure my hips dont roll in on themselves so to say. The “thigh” end of the pillow is asymmetrical. One side has a steeper curve & the other side has a shallow curve. I like that I can flip it around to whatever is most comfortable for me in the moment, as no two nights are the same (!!) And as for the “knee” end of the pillow, it appears to be symmetrical. The curve seems the same on both sides, and it really is so similar to the size & shape of my original, H or square-shaped knee pillow. I appreciate those details.
I wish the pillow cases came in a few color options, beyond greyscale & white colorways, but that’s nit-picky. I’m not exactly bummed about that. I guess at least they’re neutral options. I’m overall happy with the one I got! The material is soft. Make sure to read laundering instructions before tossing it in a washing machine, as with anything. It washed fine on delicate, cold wash and delicate, extra-low temperature dry. No loose seams. I also really appreciate the tucked zipper. On the older pillow the zipper is just there, on the outside of the pillow case & very noticeable to the touch. The zipper on this new pillow is almost hard to find, ha!

Really good quality knee pillow – finally it is comfortable lying on my side in bed with this pillow. It was recommended to me by my sister, and I can honestly say it is the best one I have ever tried.

The 14” knee pillow by Anzhixiu has made a huge difference in my sleep quality and daily comfort. I bought it to help with sciatica and lower back pain, and I noticed a real improvement after just a few nights of using it.
The pillow is incredibly soft to the touch, but still supportive enough to keep my knees aligned properly throughout the night. Unlike some others I’ve tried, this one stays in place while you sleep, which is a huge plus—no more waking up to readjust or hunt for it at the foot of the bed.
It’s also just the right size—14 inches long gives plenty of support without feeling bulky. The fabric feels smooth and high-quality, and the memory foam inside contours nicely without flattening out.
If you suffer from hip, back, or sciatica pain, I definitely recommend giving this a try. Anzhixiu nailed the balance between comfort, support, and staying power.
