Post foot fusion surgery bed wedge/elevator pillow

I had fusion surgery on my foot a week ago. Does anyone have any recommendations on devices like bed wedges or leg elevators? I am looking for something to prop my leg up on in bed to keep it elevated. I have been using a pile of pillows but they seem to collapse/shift over time, not keeping my foot elevated to the necessary level to alleviate pain.



Thank you for any recommendations.
