Multiple (community discusses DIY builds and specific brands) Mattress (DIY modular latex/pocket-coil construction)
7/10
Community sentiment is that latex-based modular mattresses (latex base plus replaceable topper(s)) hold up far longer than typical all-foam beds, with many reports of ~7–10+ years. However, heat retention and layer replacement are recurring caveats, and at least one user reports sag/back-pain leading to swapped layers.
