Lovely memory foam, removable velvet cover, neck, behind knee's, and ankle pillow.
This is the perfect pillow for me and I suspect quite a number of others also. At times, my neck, lower back, or the area behind my knees needs a supportive boost, and this handles those spots perfectly. Because it is made of memory foam, it is neither too hard nor too soft; it gives just enough without losing its shape. The washable cover is made of a really nice, soft velvet in a rich, dark gray color. There is also a hidden zipper on the back (which I’ve shown in my second photo). I actually had to wash the cover already after spilling some tea on it, and it washed beautifully right in my washing machine and also put it in the dryer. It didn't shrink at all, and the flexibility of the memory foam made it easy to put back on with very little effort. Plus, there was none of that funky chemical smell you sometimes get with new memory foam. I recently had an MRI and truly wished I’d had this pillow with me to prop under my knees—it completely takes the stress off my back and knees while easing my hip discomfort. I find it incredibly comfortable for propping myself up during the day, as well as at night to elevate my legs and prevent swollen ankles. For the price, this is a fantastic, well-made item that perfectly fits my needs. I highly recommend it!

Exceeded expectations
You don’t know how happy I was to find a bolster that looks like a long pillow. I just put it in front of my three throw pillows and it looks very nice. This one is slightly larger and is very soft.

Good foot and knee rest
The bolster fits my knees and ankles so I can sleep comfortably. I did not give it 5 stars as it is not as high as I thought.

So incredibly comfortable. Love the memory foam.
OMG. Love this leg pillow! So very soft! It stays put at the bottom of our bed and is so comfortable. It reminds me of a spa quality leg support. I have issues with my feet so I find it super healing to have my feet slightly elevated so my toes don't get wrapped up in the sheets while I sleep. And finally, the memory foam cushion is spot on.

too soft
a bit too squishy and half a foot short for me unfortunately. I'd say the squishiness is a bigger issue if you're getting it to support your knees from hyperextending. though my knees fell just outside of the ends when im not actively holding them together, which isn't helpful either.

Really helps
Works great on helping me sleep without my knee locking up. Just the right firmness, width and stays in place pretty good.

An okay knee pillow speaking from my personal use.
I wanted to love this knee pillow. It came in and I was super excited to try it to help with my sleeping posture. The problem is run into is it just flattens out to easy. That being said I am a heavier guy so maybe that's the problem, but it should say that. Definitely not a bad product, its just not the right one for me.

Received unbranded pillow
The one I received is not branded as “allsetthealth” it has no label tag and very low in height and just looks cheap and smells like its been perfumed. Packaging is also old and dirty. Returned.

Perfectly fine
It comes vacuum packed and regained its shape just fine within a day or so. I did not notice any odours on it. It’s exactly as expected and is comfortable to use. I’m a short person with short legs and I have no problems with this bolster. I bought this because I had abdominal surgery and must sleep on my back for at least six weeks, but I hate sleeping on my back. A bolster pillow like this under the knees makes sleeping on your back easier, especially if you experience any lower back pain, as it helps the lower back relax better. I would recommend this, the price was right and it works well.
