A canopy mattress is an ornamental mattress considerably much like a 4-poster bed. A typical cover mattress often options posts at every of the 4 corners extending 4 ft high or extra above the mattress. Ornate or ornamental fabric is usually draped throughout the upper house between the posts and a solid swath of cloth could create a ceiling, or cover directly over the bed.
A 4-poster mattress is a mattress with 4 vertical columns, one in every corner, that assist a tester, or upper (often rectangular) panel. This tester or panel will usually have rails to permit curtains to be pulled across the bed. There are a number of antique 4-poster beds extant dating to the 16th century and earlier; many of these early beds are extremely ornate and are created from oak. An instance of such an early 16th-century 4-poster resides in Crathes Castle, which was made for the original fort house owners in the Burnett of Leys family.
