I have the Serta icomfort medium firm hybrid and it's probably what you are looking for. My husband has a terrible back and we both love it. Our last mattress was a pillow top and I can't believe I slept on that for 18 years

My wife and I had bought a Sealy iComfort mattress but after about two years it was softer than a marshmallow and was wrecking our backs. I used to do some contract work for a smallish but nationwide maker of foam memory beds and pillows. I went to my client contact and asked him what he thought about the situation, and if he had any suggestions. He said EVERY memory foam bed (including the ones his company makes) will get softer over time. He said the only ones bed he knew of that didn't do that was Tempurpedic. He said despite where he worked, he actually slept on a Sleep Number bed. My wife and I ended up shelling out for a Tempurpedic, and it's been a pretty darned good mattress for about 10 years. Meanwhile, my mother got a Sleep Number bed that was later passed to our son when she moved into assisted living. That thing is awesome.

First time in my life where I have a mattress dilemma and found myself calling to process a return. During covid I bought a Serta icomfort and it was excellent. Coming up on 6 years I wanted to get a new bed frame and mattress. I ended up buying the Leesa + West Elm Reserve Hybrid Mattress. I tried it in the store and thought it was good but when I received it at home it was a lot more dense and firmer than the one I saw at the store. It’s so padded that it sits too high on the bed frame (also from West Elm). It was so firm I could not get any sleep the first night I tried the bed! I went out the next day to Mattress firm and bought a Sealy posturepedic (blue mattress) and it’s been so much better! All of them cost about the same price.

We have a king endy. We did medium firm. We could’ve gone with plush maybe but overall we are so happy with it. It’s as good for us as, if not better than, our old iComfort when it was new, which cost 3x more than the endy and made us both sweaty. I rotate like a rotisserie chicken all night and it’s perfect for me. Most importantly, we don’t get warm at all. Very happy with it and the price was awesome.
