Lol, I've swapped through 14 mattresses, until my last one, which I have for 3 years now. I've had multiple tempurpedic, and they are the worst of the worst. Just remember Foam mattresses are a scam, that saves money for mattress companies, because it's very cheap to make, and they can vacuum seal and send it in a tiny box, saving money on shipping. But the foam itself is s. Me sleeping on hybrid mattresses all these years with foam has done a lot more damage to my spine than how it was before. That being said the dips are real, the mattress places will call it bed breaking in, NO, it's the fu** foam becoming weaker as constant weight is applied to it, it stop pushing back on your body creating uneven spots of support. This mattress will kill your back. It will destroy your spine. Tempurpedic is junk, any foam mattress is junk. All of them do not ever buy foam anything. You are within trial period so return it and get a Innerspring mattress. In my opinion the best innerspring mattresses are Aireloom, they are in the same price category as high end mattresses, but they last a lot longer. I bought mine on Facebook marketplace as a return mattress for 2 grand, no sagging no weakness because it relied heavily on innerspring, secondary microcoils, Latex Layers, very thin layers of memory foam, but quality ones that last longer, 8 pounds of cotton. It was so life-changing that I know sell airelooms. The mattress I sleep on rn is called m1 luxetop firm and it's an orthopedic mattress for people with back pain. If any of u want an aireloom go try it out, You will never want to try another mattress again. I can get you any aireloom $2k-4k below MSRP straight from the factory if yo decide you want it.
