How long should a cot last?

I'm curious, how long can we realistically expect a cot to last? Is it a one-time investment that should last for years, or something that needs to be replaced frequently? And if so, what factors contribute to its longevity? Do materials play a role? Or is it more about proper usage and maintenance? I'm looking for guidance on how to make the most of my cot investment and ensure it stands the test of time.
