ProW can be used on top of conventional rowing seats, however, its optimal function is on top of a regular Concept2 rowing seat.
The shape of the ProW is designed to remedy problems from conventional rowing seats by redistributing the pressure to a larger area resulting in significant less pressure on a single area. This makes it possible to row for a much longer time without irritation and pain making the ProW especially valuable during long training sessions.
In the beginning it may feel quite different and unexpected using the ProW. This is due to the redistribution of the weight and pressure. It takes a little while to get used to rowing with ProW, but once accustomed to the shape, it is highly unlikely that you will ever row without your ProW again.
A unique advantage of the ProW is the fact that it adapts to your bottom with 10-20 per cent simply by use just like a pair of running shoes.
