With foam mattresses, you need to look at the density of the high-resilience foam (HR foam) that they use. Generally the higher it is, the firmer the mattress will be and less prone to sagging.
It also means it will be a lot heavier and difficult to move around. If the density info is not provided, you can just look for ones they claim are for people who are heavier than your own weight.
