I've been the sole owner of this top-notch monitor arm, but I'm parting ways with it because I've transitioned to a compact home office setup and no longer require a spacious dual monitor arm arrangement.
If you were to purchase this exact setup directly from Human Scale, it would set you back approximately $1,400 (see attach spec sheet). I'm offering mine for $500. It is in excellent condition so the price is firm.
