Systems, devices and methods including a foundation member comprising: a front Portion configured to receive a user's upper legs, where the front portion comprises a first protrusion and a second protrusion; a pommel configured to guide the user to a proper location on the foundation member, where the pommel is proximate the front portion and between the first protrusion and the second protrusion; and a rear portion configured to receive a user's lower pelvic area, the rear portion comprising a central portion and an upwardly inclined lateral portion, where the lateral portion and the front portion collectively surround the central portion.

The present disclosure relates to a seat ventilation system for deployment in a seat of a vehicle. Specifically, the seat ventilation system includes a three-dimensional mesh for maintenance of airflow channels and a ductless blower system to prevent system pressure loss. The air-permeable three-dimensional scaffold prevents compression and closure of pad-based airflow channels. The blower system reduces system air pressure loss by residing adjacent to the volume of interest, eliminating the need for ductwork.
