Tablet Holder Pillow/Cushion (Downers Grove/Darien border)

I'd appreciate a pillow/cushion designed to hold a tablet: something like shown in photos. I was fortunate enough to find my elderly mom a tablet, but it's too hard for her to hold up while using. Again, just looking for the pillow/cushion, we have a tablet. Any color, decent condition. From non-smoking, pest-free home only please. T.I.A.
