Multiple brands (mostly DIY latex + topper; references to Saatva Classic, Silk&Snow, Nectar, Sleep Number) Mattress (DIY modular latex/pocket coil build)
7/10
Reddit consensus in these threads favors modular latex-based mattresses/toppers because users report long usable life and component-level replacements instead of replacing the entire mattress. Some commenters report foam heat and layer sag with cheaper memory-foam builds, so lifespan depends heavily on construction and material choices.
