A light weight, ventilated, moisture resistant cushion on which there are opposite facings having multiple openings, such as in a net fabric, for the passage of air. The facings define a pocket between them, and each pocket is adapted to carry and restrain a pad which may be constructed from a jersey knit plastic fabric, rolled onto itself to form at least one roll of the pad fabric. The opposite facings contact opposite surface portions of the roll or rolls so that any load imposed to a facing of the cushion tends to flatten the roll a direction transverse to the center line or axis thereof. The strands of the knitted fabric forming the rolls are relatively stiff and when loaded bend and when unloaded, although not per se resilient, recover like springs.
