$1000 is enough to not be very afraid to lose a job, or to fall seriously ill. It would allow to look for a job for a longer time, or to take a lower-paying but nicer job (as in less strain, easier commute, better growth prospects, etc). It may allow to start saving some money.

It's more of a safety net than a comfortable sofa: maybe it's not as nice, but it keeps you from hitting the floor nevertheless.
