Do you recall anything that would make it possible to find any descriptions of this experiment? When I try to search for "a thousand people focus attention on a chair" I just get stuff about meditation and an "ADHD chair". Which is apparently a thing.

It sounds vaguely like the Invisible Gorilla Experiment: https://en.m.wikipedia.org/wiki/The_Invisible_Gorilla
