Today’s pocket spring mattresses were invented over 100 years ago by
English-born James Marshall, a machinist and engineer who eventually settled in Canada. The invention of the pocket spring system was originally known as Marshall coils.
Marshall established the Marshall Mattress Company in Toronto, Canada,
which has continued to operate for over 100 years. Early on he licensed rights to this design in the United Kingdom to his former employees. This company operated under the name of Marshall Mattress
of England until the early 1930s when they changed their name to VI-Spring.
Marshall conceived of a mattress whereby internal independent springs
would provide both support and comfort within the mattress itself. Marshall produced pre-compressed cylindrical coil springs, each sewn inside an individual cotton fabric pocket, which provided
uplifting support on its own.
When fitted together, the coils became an independent suspension system
that contoured to each person’s form and weight, providing unsurpassed support and comfort. When upholstered, a finished Marshall mattress not only reduced physical pressure under the sleeper, but
actually relieved it as well.
Today the invention is widely used in the World’s finest mattresses. It
is the only type of mattress we at Cotton&Co. would consider selling.
In our view the pocket spring system provides the greatest level of
support and comfort available. It is not just us who think so – the British Royal family and Swedish Royal family all sleep on pocket sprung mattresses.
