Mini table for keyboard and mouse?

Question

Do it yourself

I want to sit on the couch watching TV, but with a keyboard and mouse - toys to play on TV. You need something like a mini-table, but I don’t know what it’s called, and in general what options are there - what will be more convenient for the arms and back? It is desirable that you can lean back on the back of the sofa at the same time, and you do not have to slouch over the table.
Here are examples:

It's embarrassing that there is no elbow rest - it seems that the hands will quickly fall off (I plan to play action games and shooters). And they are all kind of small.
Who will advise what? Preferably, a ready-made solution, but a collective farm-production can also be a crutched initiative.

Answer 1

The mini-tables that you attached to the question for active work with the mouse and keyboard are not intended in any way.
An adequate solution would be something like this:

Here at least there is where to put your elbows so that your hands do not hang in the air.

Answer 2

I had one like in the first photo and similar to the last one - all this is complete garbage, I don’t recommend it: it staggers, hands hang, there is nowhere to put the mouse, etc. seating on a sofa/chair. This table is suitable for watching movies, nothing more.

Answer 3

I had 2 of these tables, both threw in the pantry. They are terribly uncomfortable, there is no place to put your hands, except perhaps as a stand for a laptop, the hand on the mouse will be on the couch. Already better at the table.
