hi eltampa,
Some of the better options and possibilities I’m aware of (including two local factory direct manufacturers) in the kansas City area are in post #2 here.
They have some stiff “competition” if you are considering any of the Dreamfoam mattresses but there is also value in being able to test a mattress locally as well. No matter what … they will give you some reference points for various firmness levels with latex which will be helpful no matter which way you decide to go.
