Wiki article on this topic: A bedroom is a room of a house, mansion, castle, palace, hotel, dormitory, apartment, condominium, duplex or townhouse where people sleep. A typical western bedroom contains as bedroom furniture one or two beds , a clothes closet, a nightstand, and a dresser. Except in bungalows, ranch style homes, or one-storey motels, bedrooms are usually on one of the floors of a dwelling that is above ground level.
In larger Victorian houses it was common to have accessible from the bedroom a boudoir for the lady of the house and a dressing room for the gentleman. Attic bedrooms exist in some houses; since they are only separated from the outside air by the roof they are typically cold in winter and may be too hot in summer. The slope of the rafters supporting a pitched roof also makes them inconvenient. In houses where servants were living in they often used attic bedrooms.
In the 14th century the lower class slept on mattresses that were stuffed with hay and broom straws. During the 16th century mattresses stuffed with feathers started to gain popularity, with those who could afford them. The common person was doing well if he could buy a mattress after seven years of marriage. In the 18th century cotton and wool started to become more common. The first coil spring mattress was not invented until 1871. The most common and most purchased mattress is the innerspring mattress, though a wide variety of alternative materials are available including foam, latex, wool, and even silk. The variety of firmness choices range from relatively soft to a rather firm mattress. A bedroom may have bunk beds if two or more people share a room. A chamber pot kept under the bed or in a nightstand was usual in the period before modern domestic plumbing and bathrooms in dwellings.
Furniture and other items in bedrooms vary greatly, depending on taste, local traditions and the socioeconomic status of an individual. For instance, a master bedroom may include a bed of a specific size ; one or more dressers ; a nightstand; one or more closets; and carpeting. Built-in closets are less common in Europe than in North America; thus there is greater use of freestanding wardrobes or armoires in Europe.
