To give a super-cozy finish, flannel is brushed on both sides, while brushed cotton is only brushed on the face side. For this reason, flannel is often fuzzier and warmer than brushed cotton.
In the 18th century, although usually made from wood, bedframes also started to be constructed using metal. Mattresses were stuffed with cotton and maids and personal valets no longer slept on trundles on the floor. The bed was not used for receiving visitors, but rather as a private space. In the 19th century, the four-poster beds were less lavish, and metal bedsprings were invented. It was during the 20th century when the water bed was created, as well as the air, innerspring, and memory foam mattresses, and now in the 20th century, we are spoilt for choice!
