My preference for sheets is 100% cotton, 600+ thread count. I purchased these because of the price. These are not weighty, luxe sheets. These are thinner, but very soft and comfortable to sleep on. The elastic on the bottom sheet is not sewed to the sheet (like most sheets) it is a big circle inside the casing. Probably a much cheaper way of designing the fitted sheet but it works well. Bottom line - I would buy these again.
