It turned out that the firm, which we have bought in the past, seemed a bit too firm. Like Goldilocks we discovered that the medium is just right.... The professionals at Tempurpedic were extremely kind in helping us get to that conclusion.
This mattress is unbelievably comfortable and supportive. I highly recommend the hybrid! It has a very slight bounce which eliminates the sinking feeling of some Tempur-Pedic mattresses. I am a side sleeper with arthritis in my hips. I never wake with pain in my hips with this mattress. This is by far the best bed I've ever slept on. Absolutely worth every dollar I spent!
So far I am satisfied with my mattress. I am hoping that the mattress will soften up somewhat more after it breaks in. I does retain a little body heat. I'm hoping that will not be an issue this summer. Overall, I am happy with my mattress and would recommend it.
My joint and muscle pain had been cut in half. My spouse who didn't necessarily want a different mattress and was happy with our 6yo pillow top has said it's the mattress they didn't know they needed. We are both sleeping our best.
