Capitol Bedding is a family owned business from the Lansing area. Malcolm X worked there in 1945 upon his return to Michigan from Boston (http://brothermalcolm.net/mxtimeline.html). He made five dollars a day there.

Capitol Bedding in 1945 had two locations, one on Michigan Ave. in the heart of Lansing's commercial district and another (newer) site on North Cedar Street. It is unclear at which location Malcolm worked.
