recumbent machine seats
On a real recumbent bike, the seat MUST be comfortable or it won't sell. Those semi-recumbent exercise machines at the gym, though, are not bought by the people who will ride them. Or, as in the home versions, they're not bought by cyclists who know better. The wife's Schwinn has lots of bells and whistles and is very quiet, but it's nowhere near as comfortable as the recumbent bike she sold to pay for it. But the bike intimidated her. (And it was too small for me.)
