What is Reddit's opinion of Knee Pillow Designed for Sciatica, Pregnancy, Knee and Hip Pain Relief - Doctor Recommended Leg Pillow for Side Sleepers to Reduce Lower Back Pain - Includes Instructional Handbook (White)?

From 3.5 billion Reddit comments

I've gotten a bit better sleep with this kind of pillow. It's smaller than it looks, keeps the hips more straight and as it can be strapped to your leg, it moves with you, less need to fully wale up to replace it.

Ok, you could try something like what I use. It's a memory foam neck/back of head pillow. I find it really comfortable though I sleep mixed back/side. I find the height is just right for comfort.

This is the one I bought:

It's sold as a knee pillow but also works for your head.
