Verdict: Community sentiment is that modular latex/coil mattresses can be durable for many years, mainly because worn comfort layers can be replaced instead of discarding the whole unit. Longevity is less consistent with all-foam designs due to heat retention and sagging in the comfort layers.

Multiple brands (community discusses DIY components and brands like Talalay latex, Saatva, Silk&Snow, Purple, Nectar) Mattress (DIY/modular build using latex/coil layers and replaceable toppers) — In-Depth Analysis

Users describe DIY/modular mattresses built from durable latex layers and/or pocket coil bases, with comfort layers (topper or upper foam) treated as replaceable parts. Several commenters report latex layers staying supportive for long periods (around 7–10+ years), while sagging is reported primarily for cheaper memory foam mattresses (sag in the middle after ~6.5 years). A recurring failure mode for foam mattresses is heat retention and/or a comfort-layer dip that prompts layer swapping. Some mention warranties and modularity as key to extending service life, while others note that even well-performing setups can require layer replacement after several years.
