My husband and I are very different weights but we've always preferred the same firmness in an innerspring mattress.  I assume the same mattress is supporting us differently; I'm lighter and don't sink in as much as he does, but my back likes the firmer support.

If we order from flobeds or sleepez we now have the option of choosing different levels of support.  But from reading here it seems that latex might have a very different response to our difference in weights.  So I'm wondering whether I should get the two sides with similar levels of support, as we've done in the past, or increase the firmness on his side, as flobeds recommends.  Can anyone help with this?  I'm not sure how latex compares to innersprings in this respect.
