The IW-J20 Pro chair is one of the coolest gaming workstations around. It fits up to 3 monitors (27″) and uses hydraulic motors to control the position of the chair. You also get customizable LED lights on the frame and 3 adjustable keyboard and mouse shelves.
Imperatorworks has taken it to the next level by building a Gatling Gun version of this chair. The IW-J20 Pro Gatling Gun Gaming Workstation just looks more badass with tank treads. The above video shows it from various different angles. More info is available here.
