Bests & Worsts Reviews from Amazon

After using this the very first night, I could feel dramatic improvement the next morning. I am 70 yo, 5'1" female, 138 lbs. I am a side sleeper. I have osteoarthritis and rheumatoid arthritis and no cartilage on right knee. Spent almost the entire year 2018 in pain. At times I could not walk without a cane. This pillow somehow seems to have realigned my hips and knees in such a way that when I get out of bed in the morning I can actually walk! It stays in place when I roll over during the night. I will say I am somewhat aware of it but it doesn't keep me awake. At times I have to struggle to find a comfortable position. Bottom line: life changing.
