ComfortAir seat cushions are seat cushions that have been scientifically designed to evenly spread and dissipate the build up of pressure points resulting from sitting statically on a seat for a length of time. Originally developed to help provide comfort for people who are wheelchair bound, the strategically shaped and positioned network of interconnected air cells instantly shifts pressure from one area of the seat to another less pressurised area. This resulting in a cushion of air, comfortably supporting the entire contact area between bottom and the seat. The shape and position of the seat is different depending on the style of motorcycle you ride. A sports bike's riding position results in more pressure applied to the front area of the seat, while a cruiser's feet-forward riding position often exerts more pressure towards the rear of the seat. Hence the design of the four different ComfortAir seat cushions - each for a different style of motorcycle.
