If you were fortunate to be wealthy in medieval Europe, then you could use your bed to show off your status. Their impressive beds were carved out of wood, raised off the floor, and often encrusted with jewels. Four-poster beds were created during these times, with velvet drapes to keep out the bugs and cold air, and to further show off wealth. However, if you were poor, you slept either on the floor or a small raised platform with hay for a mattress and a scratchy wool blanket.

However, flannel sheets can be made of cotton, wool, or synthetic fibers, leaving brushed cotton a  good balance of breathable and warm.
