I had the same problem with my 4in Roho. I did 2 things. First I got the quad Roho. The one that has 4 areas of air. So after you sit straight you lock the cushion in position The sides hold more air so your legs don't move as much. But that only helped some. So I bought after market thigh pads. They just attached to my chairs seat right on the front sides. The pads can go up/down or in/out and they hold my legs in the perfect position.
Also adjusting my feet plates helped. My single post leg rest held my feet to close together. My ankles turned and pushed my knees out. But I think the thigh pads were the best option. And if I don't wont them on they just lift off and on. This is kind of like mine, but mine are smaller, more adjustable, and easily removable. http://www.therafin.com/hipguide.htm Greg _____ I have been having problems with my sitting posture cushion's and they have me trying a 2'roho instead of the 4? roho the problem is my legs open when I am sitting does anyone have an idea?s or know of a product that would be helpful to push the knee?s closer together almost like a leg guard.
