The canopy bed came into being more for a practical solution rather than for extravagance or decadence. In fact, the earliest canopies for canopy beds were probably beds of common people seeking an additional layer of shelter beyond that of a less-than-impenetrable organic roof. Canopy beds with curtains that could completely enclose the bed were used by wealthier families in medieval Europe for warmth and privacy, as their servants often slept in the same room. Until the 16th century, these beds, even those of the upper class, were fairly plain and understated. But during this period, carved work on the headboard and posts became popular and more ornate canopy beds followed. Todays canopies for beds generally fit into one of two categories: traditional or contemporary. Most of the traditional canopy beds will have a Victorian look, with either metal rod frames or intricately carved wood frames and posts. Bed canopies will also often feature ruffled, pleated or other elaborate draping, sometimes with simple cottons, voile, lace or eyelet. In contrast, modern canopy bed canopies generally employ a cleaner, simpler design. For canopy beds wood, metal, or a combination of the two is used in the construction, usually have little to no detail on the foot and headboards and often feature sharp, geometric designs. Bed canopies are often used in styles of Moroccan bedding, retro bedding and bohemian bedding but fit equally well into country bedding designs and elegant bedding decors.
