Engineering student looking for feedback!

I don't have any "best tool" for using my computer. I was given a lovely Dell laptop computer, but I keep in on standby, and mostly use tablets. The computer is heavy on my lap. I have to lean over too far if I put it on the edge of the bed. And I don't have a table for it in the crowded space where I live. I think that what might help would be a small pedestal-type holder for the computer. Maybe it could be made so that it clamps onto the foot of the bed, or onto the edge of a dining room table, but is raised a little higher than the table, so that it is (or can be positioned) higher than the arms of my wheelchair. And, that it could be repositioned easily, so that it could be pulled in front of my wheelchair (as you would some desk lamps), but if the doorbell rings, I could push it to one side (or push it back toward the table) and quickly roll away from it, to go to the door. The concept of a stationary "desk" dedicated to a computer doesn't work for me, due to my space being full of wheelchairs, diapers, chucks, grabbers, vitamins, TV, fully loaded bedside table, and water bottles. If the little floating table had a way to secure the computer, so it can't fall off, that would be nice, too.

I'm the moderator on a very active YouTube channel, so my life does revolve around my computer. Thanks for coming here and asking!
