When I had a back injury and was laid out for a few days, I used a computer stand similar to this: https://www.amazon.com/Adjustable-RAINBEAN-Portable-Workstat...

The stand was adjustable enough such that with my thin laptop, I was able to angle the stand such that I could type and view the screen comfortably even while lying down, without the laptop falling off the stand. I mostly used the touchpad on the laptop, but I also placed my trackball on the mouse stand which was also angled, although not as steeply due to there being not much of a lip on the mouse stand to keep the trackball from sliding off. It's annoying to have to move the laptop stand to the side whenever I get out of bed, but for a short term solution it worked out well.

Those are very versatile bits of kit. I use them in bed, but also if you travel and you carry an external travel monitor with you, you can essentially use it as a monitor mount to raise the monitor to a more comfortable eye height.

I did the same exact thing. Worked great.
