The nanobionic soft coating on these sheets are made with far infrared emitting natural minerals, and is something that I had never heard about until this product came along. The natural minerals are said to activate with body heat and return back to your body enhancing blood flow. By enhancing blood flow the product claims to help your body recover from the day with a more restful sleep. I do have to say that since I put these sheets on the bed, I have not gotten up in the middle of the night for any reason. I sleep alone and when I rise in the morning, I notice that it looks as if no one has slept in the bed, which makes putting the bed back together extremely easy in the morning. The sheets are made with 100% polyester so they are virtually wrinkle free and are extremely soft on your skin. I normally sleep “hot” and these sheets do trap body heat, so I have not been able to wear my normal long pajamas but have had to switch to my summer sets. I don't mind this at all since I am not getting up in the night. The quality of the fabric is exceptional and the manufacturer says the coating will last through 50 washes. I was especially impressed with the elastic around the entire sheet. This is not just a cheap thin elastic, but one that is at least 1 inch wide and sewn right into the fabric. This allows a firm grip when tucked under the mattress. I would not hesitate to recommend this product and look forward to many more restful night's sleep.
