What is the difference between a spring reformer and a gravity reformer?
Basically they are the same concept. Joseph Pilates invented the spring resistance idea when interned as a German POW in England during WW1. At that time resources where not available to build and design complex machines, so Pilates utilized what was available and it is believed he used bed springs from under the mattresses to provide resistance. The Gravity Reformer concept ironically was first patented in Germany in 1892 when Joseph Pilates was just 12 years old. The manufacturer of the new Reformer had been manufacturing its traditional products in the USA for the last 25 years.
