A canopy bed is an ornamental bed somewhat just like a four-poster bed. A typical cover bed often options posts at each of the four corners extending four feet high or extra above the mattress. Ornate or decorative fabric is often draped across the upper space between the posts and a strong swath of cloth may create a ceiling, or cover instantly over the bed.
A four-poster bed is a bed with four vertical columns, one in each nook, that support a tester, or upper (often rectangular) panel. This tester or panel will usually have rails to allow curtains to be pulled across the bed. There are a selection of antique four-poster beds extant relationship to the sixteenth century and earlier; many of those early beds are extremely ornate and are created from oak. An instance of such an early sixteenth-century four-poster resides in Crathes Citadel, which was made for the original fortress owners in the Burnett of Leys family.
