Hi wrngway,
[quote]So I’m back for a follow up after 2 years. How’s that for a long term review?
This was the best mattress for me for about a year. The support was perfect for me. After that dips started to form where I my wife and I slept and I started to get some back discomfort.[/quote]
Thanks for taking the time to come back and share an update after 2 years I appreciate it.
I’m sorry to hear that your mattress doesn’t appear to be holding up as well as you hoped for.
It would be hard to know which layer or layer is responsible for any foam softening or sagging without taking the mattress apart and inspecting or testing each layer.
The upper layers of a mattress are generally the weakest link of a mattress in terms of durability and are the layers where the quality/durability of the materials is particularly important. A mattress will tend to soften and break down from the top layers down because the regular deflection/compression of the upper foam materials and components when you sleep on the mattress is what softens or breaks down the materials over time and the softer upper layers of a mattress will deflect and compress more deeply and more often than the firmer deeper layers and components in a mattress. On the other hand … latex in general is more durable than polyfoam so it’s also possible that even though it isn’t compressing as much the deeper support layers could be part of the issue as well.
It’s also possible that the mattress was “on the edge” of being too soft for you so that even relatively small amounts of foam softening or impressions could have taken you outside the comfort/support range that is suitable for you (see post #2 here).
Firmness is also a durability factor so if you are in a higher weight range then softer layers won’t last as long as firmer layers and even with latex ultra soft layers won’t tend to hold up as well over time.
There is more about the many variables that can affect the durability and useful life of a mattress relative to different people in post #4 here.
If you tend to prefer sleeping on softer layers that don’t hold up as well then a component mattress or a firmer mattress with a softer topper can be a good strategy because in both cases the top layer can be replaced without replacing the complete mattress.
There are also some suggestions for a mattress that is too soft or is sagging in post #4 here that may also be helpful.
