One of the things I did when I started teaching online was invest in a customized chair and workstation. When I moved, I brought it with me and had the workstation reinstalled. If and when the time comes for me to be in a power chair instead of my workstation, I'll probably go with my iPad Pro docked on my chair. Meanwhile, my custom chair is the second most comfortable piece of furniture I own. It adjusts 10 ways and has memory foam. The arms adjust inward to support my arms so only my fingers are moving. It's a great setup for now but I'll have to address the height if I want to use it when I'm in my power chair. If my arms and fingers work longer than my legs, I'll just transfer from PWC to the comfy office chair.
