Abstract
Abstract Padding for mattresses, cushions, pillows etc. comprises a soft board-like base member and a plurality of elongated padding members disposed in parallel relationship on the base member. The construction provides the mattress with a proper hardness and flexibility and enables the sleeper to maintain an ideal sleeping posture. The elongated padding members may be provided with small projections to give a moderate stimulus to the human body, and may be formed with perforations for ventilation. The elongated padding members may be provided on both sides of the base member and the elongated padding members provided on one side may be offset from those provided on the other side to increase cushion effect.
