A cover mattress is an ornamental mattress somewhat just like a 4-poster bed. A typical canopy mattress normally features posts at each of the 4 corners extending 4 ft excessive or more above the mattress. Ornate or decorative cloth is commonly draped throughout the higher area between the posts and a strong swath of material might create a ceiling, or canopy instantly over the bed.
A 4-poster mattress is a mattress with 4 vertical columns, one in each nook, that assist a tester, or higher (normally rectangular) panel. This tester or panel will typically have rails to permit curtains to be pulled across the bed. There are a number of vintage 4-poster beds extant dating to the 16th century and earlier; many of those early beds are highly ornate and are created from oak. An example of such an early 16th-century 4-poster resides in Crathes Fort, which was made for the original fort homeowners within the Burnett of Leys family.
