Im not exactly light and I use my chair for multiple hours a day. usually chairs show wear rather quickly and age poorly, this one is comfortable, supports me well, is built very solidly (its 60 pounds by itself, and the piston and caster frame are holding up well, the casters themselves are somewhat lightweight compared to the rest of the frame and the screw caps on the footrest wont stay on, but otherwise its comfy and holding up solidly. It does not feel rickety or like its going to collapse on me like the previous two chairs ive had.
