The Original Theraline covers are printed or dyed with particularly high-quality and washable reactive dyes. In order to guarantee that the cover fabrics, zips and yarns are free of harmful substances, only Ökotex 100 certified manufacturers are approved as suppliers. The fabrics used are made from sophisticated raw materials to ensure the longest possible durability even under heavy use. Original Theraline covers are always sewn to fit precisely, do not shrink and have an extra-long zip for easy putting on and taking off.
