This is a four poster bed in some hotel in England. Posters are usually ornate and decorative to support the canopy but these posters are rough and organic which gives its charm.
According to the history the canopy bed came into existence in the thirteenth century more for utilitarian means rather than for extravagance or decadence. Later adding posters in each corners to support it.
Canopy beds with curtains that could completely enclose the bed were used by lords and noblemen in medieval Europe for warmth and privacy, as their attendants often slept in the same room.
These days you don’t see four poster beds being used in many houses apart from the museum, stately homes and some large hotels. They are like a room in itself.
