More than just a sticker - the AGR seal of approval marks particularly back-friendly products. The AGR (Campaign for Healthier Backs) is an association supported by doctors and therapists which was founded in 1995. The purpose of the association is to foster research into preventing backache and to process the findings from these research efforts in order to make a contribution to dealing with the widespread condition of backache. AGR works together closely with many important medical associations. It also awards back-friendly everyday commodities the "AGR seal of approval" which received the accolade "very good" from the "ÖKOTEST" consumer magazine. https://www.agr-ev.de/en/
