We've been disappointed with this purchase. We had heard great things about your mattresses, my sister has purchased 2! My husband complains that it's not hard enough and cannot make it through the night on the mattress. I am still having issues with soreness as a side sleeper, it's better than before, but I would rather not have any soreness from sleeping, especially from an expensive mattress! I had hoped that the medium would be that "just right" support for both of us.
