And finally, brushed cotton is for those looking for something in the middle in terms of cooling/heat-retaining qualities. To turn cotton into brushed cotton, the fabric undergoes a couple of extra treatments that result in the softest flannel-like bedlinen. While both percale and sateen sheets may take a few washes to become more supple and soft, a new set of brushed cotton bedding feels like you’ve slept in it forever. It is a great year-round option because it won’t warm or cool you down excessively.
