Before purchasing sheets, make sure you know the depth of your mattress. The depth of your mattress is the thickness and size of your mattress from top to bottom. This is very important to know when shopping for new sheets as it may alter the fit of standard sheets. Mattress depth can be categorized in the following ways:
In the 18th century, although usually made from wood, bedframes also started to be constructed using metal. Mattresses were stuffed with cotton and maids and personal valets no longer slept on trundles on the floor. The bed was not used for receiving visitors, but rather as a private space. In the 19th century, the four-poster beds were less lavish, and metal bedsprings were invented. It was during the 20th century when the water bed was created, as well as the air, innerspring, and memory foam mattresses, and now in the 20th century, we are spoilt for choice!
