A canopy bed is an ornamental bed somewhat just like a 4-poster bed. A typical canopy bed often features posts at every of the 4 corners extending 4 feet high or extra above the mattress. Ornate or decorative material is often draped across the higher space between the posts and a solid swath of material might create a ceiling, or canopy straight over the bed.
A 4-poster bed is a bed with 4 vertical columns, one in every nook, that assist a tester, or higher (often rectangular) panel. This tester or panel will often have rails to permit curtains to be pulled across the bed. There are a selection of vintage 4-poster beds extant dating to the sixteenth century and earlier; many of those early beds are extremely ornate and are made from oak. An example of such an early sixteenth-century 4-poster resides in Crathes Fort, which was made for the original citadel house owners in the Burnett of Leys family.
