Advice on new mattress that I'm considering, please.

Hi scubamom,

Difference being the Hope has those little micro springs - maybe that really means more springs to sag over time?

Microcoils are a good quality and durable component and are much more durable than lower quality foam materials (see this article and post #10 here).

It’s not normally the springs that are the cause of sagging in a mattress … it’s any lower quality foam on top of the springs. If you take apart a mattress that is sagging you will almost always find that the reason for the sagging is in the foam and that the springs are still fine.

We will probably go with the Black Ava since it is 13" tall and we’d have room for the 2" PLB topper without buying a bunch of new sheets. Our daughter recently purchased a Hope but thought it really felt about the same as the Ava.

You can see the specs of the Ava plush here and the Ava luxury firm here. With the exception of the 1" of 1.65 lb polyfoam which is “borderline” for a one sided mattress … the rest of the comfort materials are low quality. Some of the layers are not just “low quality/density” but “exceptionally low quality/density” (such as .95 lb polyfoam).
