If Konrad Lightner and his wife, Jennifer had not been stuck in an elevator for 30 minutes earlier in the day, they would not have been at exactly the right place to rescue a child who fell from a third-story window.

It was moving day for the Burbank, California couple, when they were exiting the apartment carrying another load — this time, the box spring mattress to their bed.

They saw a toddler dangling from something like a television cable and placed the mattress under the window just before he fell.

Konrad guided the boy to fall on the mattress instead of the pavement. Paramedics who were called to the scene said it saved the boy's life.
