Hi ddt972,
I think you are certainly making a good quality/value choice … and congratulations on your new mattress
There is more about the different types of support systems that are generally suitable for different types of mattresses and some good sources for each of them in the foundation post here. The wire grid platform/foundations (such as the one that Dreamfoam sells here) have storage under the bedframe and can be disassembled and reassembled for moving and may be worth considering.
