A spring element unit for a padding element, especially a mattress, comprises a plurality of spring elements. The spring element consists of an open-cell polyurethane flexible foam material and comprises at least one recess. Such a spring element unit is used in a padding element, especially a mattress, which comprises a base body for receiving the spring element unit. Such a spring element unit prevents a build-up of heat and humidity between the body and the supporting padding element.
