RFM’s “ergonomics first” commitment is evident in the Carmel. The unique design with the narrow upper back shell encourages a “shoulders back” posture, which is the way the body was naturally designed to sit. Body-cradling thoracic support is created by adding a special thoracic ridge for optimal comfort. With tractor seats included as standard options, your body will feel the difference Carmel’s ergonomic seating provides.
