Sanforized is the only recognized trademark for Textile Shrinkage Control. Sanforized basically refers to sheets which have been pre-shrunk using a controlled shrinkage process that is purely mechanical (including steam and pressure treatment), without any addition of chemicals. The end result is a fabric that meets special test requirements and conforms to a precise standard of shrinkage established by the Sanforized Company. For further information refer to

Pre-wash optional

As no harsh chemicals are used in the manufacturing process and the packaging is naturally breathable cotton (No PVC) you can save time by opening your bed sheets and placing them straight onto your bed.
