I used to be into the high thread count sheets but after trying the Tempur Rayon from Bamboo Sheets, we won't go back!! The sheets are cool, warm and soft as ever!! My husband always pulls the sheets off of me but with the added width, NO MORE!!! I have now purchased 3 sets and will definitely purchase more!! THANK YOU TEMPURPEDIC FOR MY TEMPURPEDIC BED AND MATTRESSES! THE BEST EVER!!
