Solid chair as in not flimsy feeling. I am by no means a big guy, in fact I'd say extra average in the 170lbs range.  The chair feels nice to sit in, note that it has a high seating surface.  It is about 2-3 inches taller than my last chair, and I need to point my toes to touch the ground when seated fully upright. I have ordered sliders to replace the casters to lower the seat a bit.  Final thoughts, if the base mounting rails under the chair were flipped over the chair would be a proper height and an overall great chair.
