A cover bed is a decorative bed considerably much like a four-poster bed. A typical cover bed often options posts at each of the four corners extending four feet excessive or extra above the mattress. Ornate or decorative material is commonly draped across the higher area between the posts and a stable swath of fabric might create a ceiling, or cover immediately over the bed.
A four-poster bed is a bed with four vertical columns, one in each corner, that support a tester, or higher (often rectangular) panel. This tester or panel will typically have rails to allow curtains to be pulled across the bed. There are a variety of vintage four-poster beds extant courting to the sixteenth century and earlier; many of these early beds are extremely ornate and are made out of oak. An example of such an early sixteenth-century four-poster resides in Crathes Citadel, which was made for the original citadel owners in the Burnett of Leys family.
