Reprieve features a fairly normal rear end that supports the rider's "sit bones" much like any other saddle. Its mid-section, however, drops down by three-quarters of an inch (19 mm). This is to relive pressure on the rider's perineum, by not requiring it to take as much of the rider's weight as it would otherwise. Additionally, the rider's soft tissues are supported by an inflatable polyurethane bladder in the nose of the saddle. This allows the seat surface to deform in response to pressure applied by the perineum (and by ... other things), instead of simply pressing back against it.
A 3/4" dropped midsection, aligns with the true shape of the body. The shape allows the sit bones to absorb the majority of your weight. It also allows the perineal area to keep its shape, touching nothing until the sit bones rest on the saddle.
The design is evident the moment you sit on the saddle.
