Unspecified (community discusses a DIY component build) DIY modular latex mattress (pocket coil base + latex layers + topper)
8/10
Community sentiment favors latex-based modular builds for long service life, with users reporting many years of use and minimal sag when only the top layer is replaced. Failure modes mentioned are mainly heat discomfort with some foams and layer wear/complaints leading to replacement, but modularity is repeatedly framed as cost-controlling.
