In Finland, a pefletti is a simple device used in a sauna. It is a sheet of paper, cardboard, cloth, foam rubber or other soft material that is placed on the sauna bench and then sat on. Its purpose is to maintain sanitary conditions in a sauna with a wide user base by preventing genital contact with the bench. Another reason is to prevent uncomfortable feeling because of the heat. The pefletti come in both disposable and re-usable varieties. The word pefletti is a combination of the Finnish word "peffa", which is a mild slang word for one's behind, and the Swedish word "tablett".
