Scouring the internet, I'm seeing lots of measure this and that. but I'm trying to find the "formula" of how to measure the elevator clearance etc. Isn't there some sort of formula I could plug into Excel to do this??? Any suggestions would be greatly appreciated! (That's our old sofa, sadly sitting on the loading dock of our apartment. Had to donate it. Ouch!)
