Recently I contacted the staff at Natur regarding my need for more sleeping comfort for sore, aching shoulders and knees caused by arthritis. I also had experienced a severe reaction to a synthetic foam mattress topper from another company. I was pleased with the Natur solution of a custom made 2 layered (4 inch) latex mattress topper that is most comfortable plus has not caused a reaction from my body. Now I can snuggle in and sleep in comfort. I would certainly recommend Natur and their many products that I have purchased and used.
