We actually have two in our house. My wife stole mine, so I bought another.
I just got them from Amazon: https://smile.amazon.com/dp/B002L15NSK
Actually yes, and I can't believe I forgot to mention that! I definitely want to get one but so far I haven't been able to decide what. Everything has some compromise in design and the high cost makes the buy-it-before-I-try-it an expensive gamble if I choose incorrectly.
Something like this:

But i would recommend that you get a standing desk instead.
However it is good to start somewhere. :)
yeah, the space is a little tight. I usually find furniture/spaces have to be multifunction in tighter spaces. Desks = desks + TV media storage.
TV = second screen for either of the desktops + a TV
Good thing is that your desks are only 2ft deep though.
Maybe one of these alternative chairs or stoools for seating.
or one of these TV wall mounts that allows movement forward, so you can just bring the TV out when seated in the couch.
I think it's a knee chair - my mom had one that looked similar to the picture.
