A canopy mattress is an ornamental mattress considerably much like a 4-poster bed. A typical canopy mattress normally features posts at every of the 4 corners extending 4 ft high or extra above the mattress. Ornate or decorative fabric is usually draped throughout the higher house between the posts and a solid swath of fabric could create a ceiling, or canopy straight over the bed.
A 4-poster mattress is a mattress with 4 vertical columns, one in every corner, that support a tester, or higher (normally rectangular) panel. This tester or panel will usually have rails to allow curtains to be pulled across the bed. There are a variety of vintage 4-poster beds extant relationship to the sixteenth century and earlier; many of these early beds are highly ornate and are comprised of oak. An example of such an early sixteenth-century 4-poster resides in Crathes Fortress, which was made for the unique citadel owners in the Burnett of Leys family.
