A four poster be is a bed with four vertical columns, one in each corner, that support a tester, or upper (usually rectangular) panel. There are a number of antique four poster beds extant dating to the 16th century and earlier; many of these early beds are highly ornate and are made from oak. An example of such an early 16th century four poster resides in Crathes Castle, which was made for the original castle owners in the Burnett of Leys family.
