Why use a cot?

Why would someone choose to use a cot instead of a traditional bed? Is it for portability, space-saving, or perhaps for outdoor activities? Are cots more comfortable than sleeping on the ground, and if so, how do they achieve this? Are there any specific features that make cots stand out, such as durability, ease of setup, or weight capacity? Additionally, are there any drawbacks to using a cot, such as limited storage space or difficulty in finding a comfortable sleeping position? Understanding the benefits and limitations of cots can help individuals make an informed decision about whether or not to use one.
