I think that the inventions was important because in a time where travel was done primarily via train or horse-drawn carriage, a smooth ride was not something one could count on. Even minor outings could last some time, since available modes of transportation were not quite as swift as they are today. As a result, many people needed to get work done whilst commuting. This stabilizing device allowed for just that: it attached to a person’s seat and let them write without trouble in any moving vehicle.
