I was thrilled that one thing could do the job of three, but unfortunately it was a mistake. While the weight of each of my three monitors didn't exceed the weight limit for each arm, it just didn't work out in the aggregate. When I tried to set up a monitor, everything moved and shook. It was too unstable no matter how much I pulled things out. I use the main stand to mount one of my monitors and get two separate mounts for the others that I can mount directly onto the tabletop. Your mileage may vary.
