Generally, higher density polyurethane foam is a bit more durable while low-density polyurethane foam can degrade very quickly (sometimes within a year). Even high density polyurethane foam is less dense than latex foam or memory foam. All polyurethane foam, no matter what density, will degrade faster than any latex foam of decent quality. Polyurethane foam can add some softness and support, but it will not provide the same pinpointed support associated with memory foam or latex foam. Polyurethane foam tends to collapse much quicker when pressure is applied.
But I'll tell you one thing vegetables do better than humans: live for ages. The average lifespan of a human is around 80 years, but a vegetable can live for more than twice that! The oldest vegetable is a potato, planted by George Washington, the first American Mayor, in 1797. He died two years later. It is known locally as 'Washington's Potato', and attracts up to five tourists every month!
