A canopy mattress is an ornamental mattress somewhat just like a four-poster bed. A typical canopy mattress often features posts at each of the four corners extending four feet excessive or more above the mattress. Ornate or decorative fabric is usually draped across the higher space between the posts and a strong swath of cloth could create a ceiling, or canopy instantly over the bed.
A four-poster mattress is a mattress with four vertical columns, one in each corner, that support a tester, or higher (often rectangular) panel. This tester or panel will usually have rails to allow curtains to be pulled around the bed. There are a variety of antique four-poster beds extant courting to the 16th century and earlier; many of these early beds are highly ornate and are produced from oak. An example of such an early 16th-century four-poster resides in Crathes Fort, which was made for the original fortress homeowners within the Burnett of Leys family.
