We are Tempurpedic fans. We have had a split king adjustable unit for about seventeen years. The two mattresses finally needed replacing. Our previous mattresses were firm. My husband is not real picky, but after our original purchase in about 2003, said he regretted a little not getting a softer mattress for his side. So when we ordered the two twin long LuxeAdapt mattresses, we ordered one firm for me and one soft for him. He is satisfied with his. I am not with mine. The one I am using is labeled firm, but neither of us can detect any difference between his soft and my firm mattress. I don't know if mine was mislabelled or what, but it is not firm, which I prefer and need. I don't really want to go through the process of exchanging it, but I probably am. I certainly hope Tempur-pedic still makes a firm mattress.
