What is a cot called in America?

Excuse me, I've come across a term that I'm not entirely familiar with, and I'm hoping you might be able to shed some light on it for me. I'm curious to know, what exactly is a "cot" referred to as in American English? Is it a term that has a specific meaning or usage in the United States that differs from other regions? I'd greatly appreciate any clarification you can offer on this matter.
