If the bleachers you are buying do not meet these requirements then they are not IBC Compliant.
If a company is giving you these options for purchase as an alternative, then they are not 2012 IBC Compliant. The main reasoning behind IBC is to protect you and your facility as a liability and to protect all spectators that come to your facility to attend an event.
