Objective-collapse theory, collapse for large objects

[TheHeraclitus]

TL;DR

Large objects constantly collapsing or remaining collapsed longer?

Let's say we have a big object like chair. According to Objective-collapse theory, is the wave of the chair collapsing and spreading out so fast we see it in one definite position or, does the chair collapse and it remains in this collapsed state longer than microscopic objects like atoms?
