Hi Marthago,
Welcome to the Mattress Forum!
Iām sorry to hear that your Tempurpedic had a warranty defect. But Iām glad you were taken care of with a warranty replacement.
Tempurpedic has certainly changed their specifications over the past eight years (even though theyāre quite secretive about things ). Additionally, the mattress you replaced had gone through eight years of use and was sagging in the center. Also, your body has changed over the past eight years. It is quite possible that the new Contour Supreme is very close in overall feel to your original mattress when you purchased it eight years ago, and that you are simply used to the feel of the older mattress that was broken-in and sagging. Itās also possible that the new Contour Supreme (which was always a bit of a āfirmerā mattress) is a little firmer than the old version was eight years ago. Itās also possible that you like a softer mattress now more than you did eight years ago. I would tell you to focus on the here and now and start from there.
Usually a mattress that feels to āfirmā (hard) will result in pressure points and soreness. One that is too soft will usually result in low back pain, for lack of proper alignment. I canāt tell from your description exactly which you are experiencing, but your judgment of it being too hard feeling is what weāll use. At three months old, this mattress will still soften a bit as time goes on, but if youāre approaching the limit of a trial/exchange period with this warranty replacement then I guess youāll have to make a decision on what to do.
There is more about the āpressure mappingā machines like the bed match system in this topic and you can read a little more about pressure mapping systems in general post #2 here and post #4 here. While they can be helpful as a very general guideline ā¦ I would be cautious about overemphasizing their importance compared to what your body tells you and using the testing guidelines in the tutorial because they can help more for pressure testing than spinal alignment (pressure relief is not the same as spinal alignment and a mattress that does a great job relieving pressure is not necessarily the best choice in terms of alignment). They also wonāt tell you anything about the quality and durability of the materials inside the mattress. Overall these machines tend to be a ācrutchā for salespeople and an attempt to add validity and āscienceā to their recommendations, but in the end they are a mostly a sales tool to point you toward products in their store.
If youāre being allowed to exchange your mattress, I would go back to the store and test the mattresses as if you were a new customer. While Tempurpedic isnāt a brand that I recommend to members of the forum due to their overpriced nature, you said you are a Tempurpedic fan so you could try some of the softer Tempurpedic options in that lineup. If youāre not being allowed to do an exchange and you desire extra comfort, you could always investigate a memory foam topper for your mattress.
I donāt keep track of what mattresses people switched to when they made a new purchase (it would be too cumbersome and in the end wouldnāt provide any meaningful data for people here to use), but even if I did I would tell you to trust your own opinion of comfort. I canāt speak to how any mattress will āfeelā for someone else in terms of firmness, ācomfortā, or PPP because this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances ā¦ outside of PPP (which is all about how well you will sleep on a mattress) the most important part of the value of a mattress purchase is itās durability and in terms of durability a mattress is only as good as its construction and the type, quality, and durability of the materials inside it (which is all about how long you will sleep well) regardless of the name of the manufacturer or the name of the mattress on the label.
Iām not entirely sure of what options you have at your disposal or what youāre considering, but to give a very general answer to your question, there certainly are people who go from firmer to softer mattresses over time. However, Iām not sure if that applies in your situation. I would focus less on what you used to like and more on what is appropriate for you right now and make that choice within the scope of the options that are being presented to you by your retailer.
I hope that information is helpful!
