I love my sheet! I also bought a pillow cast from another company. My sleep has been so good!! I remember the first morning after waking, I found myself talking to myself. lol!! Saying “OMG that was some good sleep!! I love getting 6-8 hours in whenever I can! My joint pains seem to be going away. I have stairs and for a while now it’s been becoming more and more painful to use them. But now it seems to not be much of a problem at all. I’ve had them for about two weeks now. After washing, they still work great!! My pillow case came with a pen to test it. Both products work perfectly fine, before and after washing. Laundry detergent only, no softeners can be used! Great product!!
