A mattress that matches the firmness preferences of my wife and me has been difficult to find. She prefers a softer mattress and I prefer a firmer one. That is a tall order, and we have finally found a mattress that fulfills both of our needs. The Serta Alleene King-size Plush Mattress Set is the best compromise that we have found. It is truly firm enough for my tastes but not too firm for my wife's comfort, and soft enough to satisfy her but not too soft for me. If any other couples have similar situations, I would sincerely recommend that you try this mattress set. Service personnel that delivered the mattress set were in and out in no time, very efficient, and also took my old set when they left. Couldn't ask for more.
