Comment Zero Gravity Chair (Score 1) 262
I use a quality zero gravity chair, LCD arm, logitech trackball and ergonomic keyboard.
Zero gravity chairs do not actually reduce gravity, but they do reduce the amount of fatigue your body experiences due to gravity. They are modeled after chairs astronauts use when escaping Earth's gravitational pull which is multiple times what we typically experience on earth. With a zero gravity chair fully reclined, your legs are above your heart causing a reduction in your blood pressure and risk of blood pooling and clotting in your legs.
Despite having a very comfortable setup, I make a point of getting up periodically to walk around and relax my eyes by focusing on objects in the distance.
