Early Medieval Standard of Living Was Low

On the material side the life of the feudal class was rough and uncomfortable. The castles were cold and drafty. If a castle was of wood, you had no fire, and if a stone castle allowed you to have one, you smothered in the smoke. Until the thirteenth century [C.E.] no one except a few great feudal princes had a castle providing more than two rooms. In the hall the lord did his business: received his officials and vassals, held his court, and entertained ordinary guests. There the family and retainers ate on trestle tables that at night served as beds for the servants and guests. The chamber was the private abode of the lord and his family. The lord and lady slept in a great bed, their children had smaller beds, and their personal servants slept on the floor. Distinguished visitors were entertained in the chamber. When the lord of the castle wanted a private talk with a guest, they sat on the bed. The lord and his family could have all the food they could eat, but it was limited in variety. Great platters of game, both birds and beasts, were the chief stand-by, reinforced with bread and vast quantities of wine. They also had plenty of clothing, but the quality was largely limited by the capacity of the servant girls who made it. In short, in the tenth and eleventh centuries the noble had two resources, land and labor. But the labor was magnificently inefficient and by our standards the land was badly tilled. Not until the revival of trade could the feudal class begin to live in anything approaching luxury.
