Perfect size, stays in place all night
Exactly what I needed to replace my cylindrical foot pillow. This one stays in place all together and it is SO SOFT. Better than expected. I even like to use it for my knees, though that was not the intention. Im a stomach sleeper with achy ankles and this relieves the uncomfortable position your feet lay in when sleeping on your stomach. Good purchase for sure

Pillow Has Many Uses
This works for knees when I lie on my back, works to prop my arm up when laying on my side makes a good head prop when I watch movies in bed. Easy to wash pillow case although I would love to find black cases for it. It's thick and firm enough to hold up whatever needs to be held up and the shape is perfect.

Works Well, Missing Certification
Received yesterday. Nicely packaged, plumped up easily, kept my knee raised throughout the night, and plumped back afterwards. The only issue that I have is the following: Product description claims OEKO-TEX Standard 100, but it is not found stamped anywhere on the box or the product, so therefore, not OEKO-TEX, which is important because it bans the intentional use of PFAS; their labels and certificates confirm the safety of textile products from all stages of production. I specifically purchased this bolster pillow because of the positive reviews, and mostly because of the OEKO-TEX certification, which appears to be false.

Controls tingling in feet at night
Very comfortable to muse. My feet had numbness and tingling at nights untold I used this product Highly recommended

Great for Arthritic Knees
I have bad arthritis in my knee and lots of bone on bone pain. I will likely need a knee replacement in the future but trying to make that a long time from now. Getting comfortable at night with no pain is extremely difficult. My new doctor suggested getting a pillow to help bring comfort. Most pillows I have found are designed for side sleepers but since I'm both a back sleeper and side sleeper none of the ones that popped up on Amazon would work for me until I came across this one. I have been using it for about two weeks now and it has made a such a difference for getting a good night's rest. It fits comfortably underneath my knee when I'm sleeping on my back and then between my knees when I roll over. It has just the right amount of firmness and soft cushion. I can use it with both legs or just one and I mostly use it with just the one. If I forget to use it one night, I wake up in so much pain and feel so stiff. I like that it has a zipper so it can be taken off and washed. I haven't done that yet so can't write about that but it's a nice addition for when I do. This has been a game changer for me and I will be taking it with me wherever I go including vacation.

Not as soft as others
(Tldr; I wanted one that's shaped like this one, but as soft as the other one.) Meh. I've had this for a few days, I'll give it another week and if I change my mind I'll revisit this review but for now three stars. I wanted this to go under my knees to relieve some pressure, but since my legs don't even sink into this it's not doing its job. Hopefully it will soften up like the other one from Sleep Innovations but that deep hand print they're showing here isn't even close to accurate. I mean, those two split pics with my hand I'm leaning into that thing as hard as I can (knuckles are even a little white) and then pulling my hand back and taking the picture, less than 1/4 second and it springs back. I was trying to catch it with at least a small indentation, but that's just not gonna happen. Might look like it's bowed in a bit or the fabric is wrinkled but there's no handprint. Then in the video when I hit the white one you can barely hear anything, when I hit the gray one you can hear things on the table shaking because it's not absorbing the hit. Great for a little drum solo, but that's not why I bought it. (you can kind of see some fingerprints in the video, but by the time I get back to hitting it again they're gone.) Edit: well it took them 8 days to post this review so I will just say it isn't really getting any softer so 3 stars it is. It would make a better knee pad than leg pillow. I gave this to somebody else and will continue to use the other one in the video even though it's flat and not exactly what I need but it is a lot softer and way more comfortable for me. Only took a couple hours for that thing to un-shrink itself, but I let it sit overnight just to be sure.

Very Comfortable
The quality of this knee pillow is amazing. It is very versatile, and due to its height can be used as a lap pillow as well. Extremely comfortable, sleeps cool not hot, and the appearance is what you see in the photos.

Supportive, Comfortable, and Worth Every Penny!
The 5 STARS UNITED Knee Pillow has been a game changer for my sleep routine. I primarily sleep on my back, and this half moon bolster provides just the right support under my knees to ease pressure on my lower back. The memory foam is firm yet comfortable—it holds its shape throughout the night without sinking too much. What I appreciate most is how it helps with my sciatica. Since I started using it, I’ve noticed a reduction in tension and stiffness when I wake up. The cover is soft, removable, and easy to wash, which is a big plus for maintaining cleanliness. This is a great product for anyone dealing with back pain, leg fatigue, or looking to improve their sleep posture. Highly recommended! Pros: Firm yet comfortable memory foam Great for relieving back and sciatica pain Stays in place during the night Soft, washable cover Ideal for back sleepers or leg support Cons: Might be too firm for those looking for a plush pillow A little bulky for travel use

Comfortable….
The 5 STARS UNITED Knee Pillow was purchased after a TKR operation to help with leg exercises and general comfort during recovery, and it helped. The memory foam gives good support without being too firm, which made it useful for positioning my leg correctly while doing exercises. It was also very helpful at night, as I could rest my operated leg on it when trying to sleep on my side, which took pressure off the knee and felt much more comfortable. The pillow holds its shape and feels well made, and it’s a simple but effective aid during recovery. Overall, I think, this was a worthwhile purchase and a helpful support cushion both for exercises and for sleeping.

Prima artikel
Doet wat het moet doen! Ik heb veel last van mijn onderrug en dit kussen verlicht de ongemakken daarvan er goed! Zowel onder de knieen, als tussen mijn knieen als ik op mijn zij lig en zelfs als ik op mijn buik lig en hem onder mijn enkels leg.
