A support panel assembly includes a lower panel, an upper panel pivotally coupled to the lower panel by a central pedestal, and a first pressure sensor coupled to the central pedestal. In at least one example, the central pedestal is formed of an elastomeric material. In at least one example, bumpers extend downwardly from a lower surface of the upper panel. In at least one example, a sealing closeout extends around peripheral edges of the lower panel and the upper panel.
