I just bought an Indy 3i through the online store of BIKELINE (a chain of Delaware/Pennsylvania bike shops). The Electra website specs the seat as: "Electra Custom Low Profile w/Double Coil Springs". I added a retro tail light, a Roadmaster repop headlight, and a small 12 volt siren on the handle bar powered by a Milwaukee Tool M12 Li battery in a red leather bag. Screaming red and screaming loud!
