Learned at Bessinungstagen know ...

I spend an average of about 1 hour in prayer and kneeling on the floor (with cushions) often sleep my legs, and lying down on the chair and I'm missing the "intrinsic" attitude; o). The best postion for me has been that of the knees. Until I came across this bank:

No numb legs more, straight upright posture, even stable Isere Direction, barely uncomfortable or interrupting slip back and forth and you can lie down the focus where it should be straight / want.

Personally, I find this part super and am very grateful to be able to handle my home so pray better.
