Marshall coil
Marshall coils, also known as encased coils or encased springs, (most commonly known in North America as "pocketed springs") are component parts of a mattress in which each coil is separately wrapped in a textile material.
==History==
Marshall coils were invented in 1899 by English-born James Marshall, a machinist and engineer who settled in Canada. He received a Canadian patent〔Marshall, James. "CA 68628." Canadian Intellectual Properties Office. Canadian Intellectual Properties Office, n.d. Web. 5 May 2014. .〕 in 1900 for his unique invention. He received patents in the United States〔http://pdfpiw.uspto.gov/.piw?PageNum=0&docid=00698529&IDKey=266E78ED093B%0D%0A&HomeUrl=http%3A%2F%2Fpatft.uspto.gov%2Fnetahtml%2FPTO%2Fpatimg.htm〕 and United Kingdom.〔http://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=1&ND=3&adjacent=true&locale=en_EP&FT=D&date=19020429&CC=US&NR=698529A&KC=A〕〔Careless, J.M.S.

This company operated under the name of Marshall Mattress England until the early 1930s when they changed their name to VI-Spring. James Marshall established the Marshall Mattress Company in Toronto, Canada, which has continued to operate for over 100 years.〔.〕
