Kristina, I had difficulty with my feet sliding when I tried to push myself up in bed, and I remembered a product called dysom that we used to help geriatric patients from sliding off their recliners. My home PT brought a piece that I am still using nine months later. It is a tacky film that many rehab departments have for positioning. It comes on a roll like foil, and they cut off a length for you. When I lay down in bed, my cALS places it under my feet, and it gives me enough traction to bridge, and I also use it to stay up in bed sometimes. It loses its traction if lint accumulates on it, but all you have to do is rinse it with plain water and let it air dry. It has been a huge help. Good luck!
