A canopy bed is an ornamental bed somewhat much like a 4-poster bed. A typical canopy bed usually features posts at every of the 4 corners extending 4 ft high or more above the mattress. Ornate or decorative fabric is usually draped throughout the higher area between the posts and a solid swath of material may create a ceiling, or canopy straight over the bed.
A 4-poster bed is a bed with 4 vertical columns, one in every corner, that support a tester, or higher (usually rectangular) panel. This tester or panel will often have rails to allow curtains to be pulled across the bed. There are a variety of vintage 4-poster beds extant dating 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 4-poster resides in Crathes Fort, which was made for the original castle owners in the Burnett of Leys family.
