Unspecified (various DIY/mattress-layer systems discussed) Mattress (DIY modular build with latex layers and/or pocket coil base)
8/10
Community sentiment favors modular latex (often Talalay) and/or pocket coil bases because individual layers can be replaced rather than discarding the whole mattress. Reported lifespan is commonly multi-year to decade-scale when the base latex stays intact, though some users report heat or eventual sag requiring topper replacement.
