Various (community discussion) Mattress (DIY/modular latex + coil base concept)
8/10
Community sentiment favors modular latex/coil mattresses because individual layers can be replaced instead of discarding the whole unit. Multiple users report multi-year durability (often 7–10+ years) with sag localized to comfort layers, though some report heat issues with foam/latex and some complaints about DIY/assembly practicality.
