Word! My desk at home is a very wide T-shaped desk made of three Kallax and two kitchen countertops: I share it with my wife and there are four monitors, two desktop PC towers (inside modded Kallax), two laptops, one shared printer, etc. and we've still got plenty of room on the desk.
Our chairs: we've each got an Aeron (mine is just out of warranty, 13 years old and the wife's got an used one, don't know how old but older than mine). That's quality stuff (it took me a few minutes to set up correctly: when you put your hands behind your head, an Aeron should lean back and then when you put your hands above the keyboard, it should move forward)... Fun fact: neighbor's kid sat in my chair (by himself, I wasn't offering him to try it) and exclamed "wow, that's a good chair!". My Aeron has already been to four countries with me. The "hit hurts my leg" is bullshit from people who haven't spend the 15 minutes needed to read the manual to set it up correctly.
