ABSTRACT:
A mattress ventilator is formed by a disk of sheet metal drawn with an array of tubular protuberances having tubular cross-sections which are very small compared with the area of the disk, open ends of the tubular protuberances being retrovertable by a die into roses for holding the disk in a mattress border. Such a ventilator can be applied to a mattress border by pressing the tubular protuberances through the border from an outer surface and retroverting the distal ends of the protuberances to form roses crimped against an inner surface of the border. The penetrations of the material of border are limited to the size of the tubular protuberances, and the perforated areas are supported and covered by the disk and act as stress reliefs for each other.
