i have slept with pillow between knees for 15 years due to low back pain. It doesn't affect this issue if my knees are still bent.

It doesn't hurt to have my legs bent. My knees hurt if I have the stretched out for to long. I have to place a pillow under my legs when I sit in my recliner.

Hello have you tried putting a pillow between your legs , it not only helps your knees but also your spin ! try and see , no harm no foul ! just a suggestion ! love always michele
