Multiple (community discussion; components sourced from different brands) DIY modular latex pocket-coil mattress (layered latex + optional pocket coil base)
8/10
Community consensus is that a modular latex-based mattress system tends to age slowly and can stay comfortable for many years. Durability improves because individual layers (especially toppers) can be replaced instead of discarding the whole mattress, though some report comfort/heat issues depending on foam type and setup.
