Not specified (community discusses DIY builds from multiple retailers) DIY modular latex mattress system (latex base + latex topper, optional pocket coil base)
8/10
Community consensus is that modular latex mattress systems have strong longevity, with users reporting ~7–8 years of minimal degradation and long-lived bases. The key durability advantage is replaceable comfort layers (topper) rather than full mattress replacement, though some foam builds show sag in the middle over ~6–7 years.
