The present invention is a portable, intelligent, ergonomically adjustable body-seat cushion controlled wirelessly via a smartphone or tablet app. Multiple air bladders embedded in the body-seat cushion inflate/deflate at the direction of the app to manipulate the physical position of the user's neck, back, posterior, legs, and feet in order to: (1) alleviate pressure on the back and sit-bones; (2) lengthen the user from a normal sitting position to a lengthened sitting position; and (3) increase blood flow to the user's extremities. Positioning algorithms in the app use the user's anthropometric data (body measurements) and seat measurements (including available space above and in front of the seat) to generate one or more air bladder fill instructions to lengthen the user. The app then wirelessly transmits the positioning instructions as well as optional motion, temperature, and vibration instructions to one or more wireless receivers in the seat cushion.
