Its is time to buy

Hi Jdavis,

A “standard” innerspring mattress will usually have several inches of polyfoam in the comfort layers and possibly some synthetic fibers although of course I don’t know the construction for certain (it could even use cotton but this would be much less common) and after that long it would normally be well past it’s useful lifetime and it would be unusual if they hadn’t softened.

You would most likely feel a difference between having one layer of latex and two yes (the upper layers contribute to “feel” more than the deeper layers) but it would depend to some degree on how deeply you sink into the mattress and on what you tend to “feel” on a mattress. This would partly be based on your body type and sleeping positions and partly on the “type” of softness/firmness you are most sensitive to (see post #15 here). The difference between two layers and an all latex mattress would be less obvious initially but it could also make a difference in how you feel in the morning because latex is much more adaptive and has more elasticity and can do a better job of contouring to your body in all your sleeping positions and maintaining firmness and support as it compresses more which helps to maintain the natural alignment of your spine. In terms of durability a mattress will tend to soften and break down from the top down so the deeper layers are not the major issue in the durability of a mattress.
