Unspecified (community discusses DIY modular mattress components) Build-your-own modular mattress (latex + pocket coil base with replaceable layers)
8/10
Community sentiment favors DIY modular mattresses using latex layers because damaged comfort layers can be replaced without discarding the whole mattress. Longevity claims are strongest for latex bases and topper-layer replacement, while memory-foam builds are reported to sag within years.
