Multiple component makers; discussed as a DIY build DIY modular mattress (latex/pocket coil hybrid with replaceable layers)
8/10
Community consensus is that modular latex-based mattresses have strong lifespan characteristics, with many reports of 7–8+ years still feeling close to new. Sag and heat issues are reported mainly with cheaper memory-foam builds, while latex durability is repeatedly contrasted with full-mattress replacement when only top layers degrade.
