Abstract

This invention discloses a pad and an elastic cylinder for the pad. The pad includes a foam layer and at least one elastic cylinder. The foam layer has a top surface, a bottom surface, and at least one receiving hole penetrating the top and bottom surfaces. The elastic cylinder includes a tube portion received in the receiving hole, an upper baffle disposed at the upper edge of the tube portion and above the foam layer, a lower baffle disposed at the lower edge of the tube portion and below the foam layer, and at least one vent hole disposed in the tube portion. The upper baffle has a first annular portion and a plurality of first extension portions extending outward from the first annular portion, making the outer edge of the upper baffle non-circular. Therefore, the pad eliminates the feeling of foreign objects and provides better breathability. It has excellent support and cushioning properties, and the support of each part can be set or the required firmness can be adjusted as needed.
