We got these sheets in white, queen size, as a wedding gift, and three months later are pretty happy with them overall. VERY soft and luxurious-feeling; fitted sheet stays on the mattress without straps. I heard that the essential amino acids found in silk is said to delay wrinkling of the skin, be good for the hair, and help calm you to help you get a restful night's sleep. Overall these sheets were the softest sheets I had ever slept on.
