Box spring beds – There are a lot of them on the market just now, and that means great confusion amongst end consumers. What makes a good box spring? And what should you stay away from? To give customers some guidance, DGM has now introduced a quality label that is only issued to manufacturers whose box spring beds have been examined closely, and also comply with the strict DGM requirements. RUF|Betten is proud to carry this label. All RUF box spring beds have been tested, certified and fully comply with the quality requirements of DGM. A great feeling, right?
