Lorraine, would it be possible to have a 36" vertical grab bar installed (about waist to floor level) somewhere central to your main activity area? So you could inch over and have something solid and stable to help pull up on if you fall again. It's hard to find furniture that is at the right height or stable enough to lever yourself up with. Before I regained my knee flex, I would use the sofa, but it sure was a struggle to boost my back high enough to get my legs under me.
When I fall or practice getting up I use my front porch, I scoot to my porch and put my legs under me and stand up or use my steps to get my legs under. I don’t know what my neighbors might think! Lol
