Reddit reviews Mobo Chair Mount Ergo Keyboard and Mouse Tray System - 2.5-Inch x 12.5-Inch x 7.5-Inch - Black

It's okay, I can see how it would be a sarcastic question. Can't see feeling through text so it's understandable. I found this on Amazon though, does it look like what you're looking for?

edit: I know it's not a chair/tray combo. But if you picked up a nice inexpensive computer chair you could just attach it I'm sure.

Here is what has worked for me for years:

• Microsoft Natural ergonomic keyboard
  
• Logitech Trackman for general mousing. I switch to a G5 for pixel work and gaming. Keep both plugged in
  
• breaks every hour for the back
  
• The big one: A Mobo chair mount. I can't recommend this one enough. I was having major pain in my right shoulder from mousing. Got one of these and the trackball and the pain was gone in two weeks. Simply put, it keeps you from leaning over your desk and extending your shoulders. Not cheap but worth every single penny.

Maybe something crazy like this if you've got a chair to mount it to.

I've also found this little chair attachment called the Mobo Chair Mount, anyone have one?

I attached it but it was set up to do that. I just added some heavy duty velcro to keep everything stable.

Use a lap desk or mount a board across the arms of the chair. If you are willing to buy a gaming treadmill I'm sure you could buy or mod a command chair. I know some companies sell mouse island sleeves for chair arms already.

edit: personally I would probably make something similar to the mobo thing out of wood myself or mod a nice keyboard tray to fit to chair rather than deal with flimsy plastic and small islands.
Beanbag bottom lap desks would be great but aren't wide enough for my g13 +keyboard+mousepad/mouse which is about 2'10" across all three if I am using a G19 keyboard. There are smaller keyboards out there though. If I didn't have to type messages in a game I could skip the keyboard altogether and just use G13 + mouse on an island at the end of each arm of my chair but that's not realistic for overall use dropping out of games.

Fits most chairs with arms, even ones with big curves (there's a curve adapter included for each arm). For this setup you just need the arms and foldout pads, the keyboard tray stayed in the box.

I've been plotting these:

I don't use a desk.

Seriously.
