"and I dont have to gain 50 lbs."

Darn, that is what I was going to suggest, think of all the ice cream, cookies, chocolate, pie, etc.

I have read a few threads where it was posted that some other folks having the same problem (light weight) actually made some sort of shim from a small piece of wood (like "popscicle stick" or craft stick) to compensate for low body mass. Some times you might have to bend an actuator arm to affect adjustment if the switch lacks any real adjustment provision.

I was going to suggest beer!

Beer and Ice cream sound a lot better than what I did. There was no adjustment and the switch is under the center of the seat about 1/4 inch below the cushion itself. Its the first one I have seen like this,as in the past the switch was activated by pressure on the seat coil springs. New is not necessarily better.
