This link shows a talk with Chase Voelker from fusion who gave detailed information about how to select the right sheet for our bed. He describes about the selection of sheets based on the thread count, tensile strength and fabric hand etc. He had described about these concepts and had illustrated some approved brands of bed sheets. Suphima supreme luxury, Beech etc. are the example of branded sheets. Depending on how we like to sleep we can select sheets of different thread count (400 to 500), tensile strength indicating different durability and fabrics ranging from crispy to soft touch sheets.
