I bought one for myself and one for my wife. My wife said it was too thick for her and didn't help so I adopted hers. I am 6'4" and weigh 250 pounds and put one pillow just above my knees. The strap is very handy as I typically switch from 'left side' to 'right side' throughout the night. It isn't necessarily the separation that helps me as much as keeping my 'upper' leg from falling forward and twisting my lower back out of alignment. This, the pillow does a good job of. I did try to use my wife's pillow as a second pillow between my legs but it was just too much. Then I noticed the shape of the pillow might accommodate my head. I wear a full face CPAP mask which would get pushed loose on my traditional pillow. I tried the knee pillow as a head pillow, placing my face on the thick edge and allowed the face mask to project from the pillow free from pressure of any kind. It worked! Since I roll over from side to side through the night, the mask just projects from the other side as I settle in. Just remember to get your face up on the thick part so the mask doesn't touch the pillow. The knee pillow will stay securely between your legs and it becomes second nature to keep your legs together as you turn from side to side. This is not a 'cure all' but it will help keep your lower back from going out. I also use an inversion table and do lower back exercises every day. All in all, I would say this pillow is good as part of an overall treatment regime to relieve back pain. Oh, and it doesn't stink. I would buy this again, if for no other reason than it has a strap that helps keep it from getting lost in the bed. (strap was removed for use as a head pillow)
