ELI5: What do dryer sheets actually do?

I get that they supposedly make the fabric softer but how do they make it softer? What are they physically doing that softens?

They coat the laundry in chemicals that feel soft. Not actually good for your laundry.

Can wreck some athletic clothing and towels and some types of fabric. 

Dryer balls are better if you feel you need something else in there.
