n our genre of endurance kayaking we choose to sit on our ends, for hours on end. So we need to take the pressure off. High school physics taught us that to reduce pressure points we need to spread the load over a wide area. To make a seat comfortable over the long periods we paddle in endurance racing, we need to reduce any pressure points.
Pressure = Force/Area
Force is paddler’s weight downwards. The area is the surface area of the bum/seat interface. It stands to reason that the pressure (and soreness) will be reduced if we make the area that supports the paddler’s weight as large as possible. I have carefully designed the Bumfortable kayak seat to do this with nice soft, warm foam, including an extended area around the hamstrings. In doing this though I have also been careful to reduce the pressure on known tender spots such as the ischial tuberosities (bum bones).
