For 30 years we developed and tested foam compounds and we have found Comfort Cell® is the best at providing long term resilience, support, shock absorption, shape retention and weight dispersion. Corbin foam is a closed cell type of foam which means the tiny air pockets can't be squeezed out of the material which gives it long lasting properties whereas soft foam breaks down and leaves you with no support. Our Comfort Cell is a purpose built material made specifically for motorcycle saddles. It works in conjunction with our patented integrated molding technology that allows us to cast an ergonomic shape and vary the density of the foam to best suit the requirements of the saddle. Depending on the design, we commonly run our foam almost twice as dense as stock. This is for long term resiliency and rider weight distribution. It really works but you'll never know 'till you spend some time on it.
