A cover bed is a decorative bed considerably similar to a four-poster bed. A typical cover bed usually features posts at each of the four corners extending four ft high or extra above the mattress. Ornate or decorative fabric is often draped across the upper house between the posts and a strong swath of material might create a ceiling, or cover straight over the bed.
A four-poster bed is a bed with four vertical columns, one in each nook, that assist a tester, or upper (usually rectangular) panel. This tester or panel will often have rails to allow curtains to be pulled across the bed. There are a number of vintage four-poster beds extant relationship to the sixteenth century and earlier; many of those early beds are highly ornate and are made from oak. An instance of such an early sixteenth-century four-poster resides in Crathes Citadel, which was made for the unique castle homeowners within the Burnett of Leys family.
