Users describe DIY/modular mattress builds using latex layers (often Talalay) and pocket coil bases, emphasizing replaceability of the comfort layer rather than replacing the entire mattress. Several comments claim latex components hold up for long periods (e.g., 7–8 years) and that sag usually concentrates in top comfort layers, which can be swapped later. Memory foam is frequently reported to sag in the middle after several years (about 6.5 years in one case) and to run hot for some sleepers. Construction-specific durability themes include modular layer replacement (topper/comfort layer) and coil bases with tighter edge/middle support. Reported downsides include stiffness/firmness complaints for some latex builds and practical issues like difficulty moving flexible mattresses and occasional back pain when the wrong configuration is chosen.
