A cat sling.
You ever see those baby slings? Yeah, like that. Because what happens is, the cat gets into my lap and then gradually starts to fall out.
Now, I like having him in my lap, but I don’t like being committed to holding him there. Yet it seems kinda cruel to just let him flop onto the floor due to excessive relaxation. Also, the mid-flop flailing can be hazardous.
