The portable seat includes a collapsible frame having a pair of oppositely disposed longitudinal side rails, each with front and rear ends, a front support attached adjacent the respective front ends of the side rails, and a rear support attached adjacent the respective rear ends thereof. The supports extend downwardly and support the side rails in a rear-to-front inclined and parallel relationship when in open condition. The side rails are foldable outwardly between closed and open conditions. The seat further includes a flexible cradle selectively attached to the frame having a contoured recess for comfortably receiving and supporting the infant in use. The cradle further includes a head roll member situated adjacent and between respective rear ends of the side rails in use, and a leg roll member situated adjacent the respective front ends.
