What is the softest bedding material?

There are many fabrics available in the market, among which cotton is the most popular one. Cotton bedsheets are known for their softness and their bright colours. Among all the types of cotton, Egyptian cotton is of premium quality and softest among all. Egyptian cotton and silk both are close competitors for the title of \'softest bedding material.\' They both have premium qualities and more costly than others. Technology is developing fast, and day by day, we reach closer to building and replacing natural items. Microfiber is one such fabric. It has properties very similar to cotton and as soft as that only. Though there is a scope of improvement, there is a chance that it will make its place in the market and replace cotton completely.
