So I have a full sized Naturepedic EOS with 8” firm base coils and 3”mini coils and it has started sagging recently and it’s not covered under warranty. I’m 5’3” about 160 lbs and the bed sinks so much when I lay on it that I had to roll up a cotton blanket and use it as lumbar support until I can fix this, I bought this mattress in February this year 2026. I saw that TPS has quad mini coils that are also 3” but says it’s 6” compressed into 3” casing, so hopefully these will be firmer and last longer? I love latex but it sleeps to hot for me so I prefer coils. Any advice would be great. Also what difference does “zoning” make in coils?
