Community-referenced (no single manufacturer) DIY Modular Mattress (latex + pocket coil base + replaceable toppers)
8/10
Community consensus suggests latex-based modular mattresses can achieve long service life, largely because sagging is often confined to replaceable comfort layers. Users report 6–10+ years of use with minimal degradation when using latex base layers and swapping toppers as needed, though comfort and temperature can vary by material and setup.
